16. Abstract Field experiments were conducted over a four-year time period (1995-1998) to evaluate herbicides for the control of weeds
on roadside grasses, woody ornamentals, and wildflowers. Imazapic (Imazapic Applicators Concentrate, Plateau) was found to be a suitable alternative to MSMA for bahiagrass management on bennudagrass roadsides. Depending upon the application rate, . imazapic controlled or suppressed bahiagrass growth and seedhead development. Bennudagrass displayed acceptable tolerance to imazapic. MaN 37536 effectively controlledjohnsongrass, and in a related experiment MaN 37536 did not adversely injure bahiagrass and common bennudagrass.
No herbicide mixture evaluated provided significant winter weed control advantages over the use of glyphosate (Roundup
Pro) + sulfometuron (Oust) + chlorsulfuron (Telar). However, the inclusion of dicamba (Vanquish), clopyralid (Transline), or
(triclopyr) Garlon 3A with glyphosate alone or with glyphosate in combination with sulfometuron was effective for winter weed control and should be utilized as components ofa long-tenn herbicide rotation strategy.
Hairy fleabane was effectively controlled with March applications of glyphosate + sulfometuron, glyphosate + sulfometuron + chlorsulfuron, clopyralid alone, or clopyralid in various mixtures with glyphosate, sulfometuron, or chlorsulfuron. Late May
applications of triclopyr, clopyralid alone, or clopyralid tank-mixed with MSMA or glyphosate were the only herbicides that provided greater than 80% control of hairy fleabane.
Three crimson clover cultivars exhibited excellent tolerance, including no effect on seed production, to DE-564 (diclosulam) applied at the vegetative growth stage. Crimson clover was not tolerant to imazapic. Wildflower species tolerant to prodiamine (Endurance) applied immediately after seeding were cornflower, California poppy, annual gailliardia, blackeyed susan, scarlet flax, scarlet sage, baby blue-eyes, annual coreopsis, and cosmos. Non-tolerant species included yarrow, baby's breath, com poppy, and lanceleaf coreopsis.

INTRODUCTION
Grass shoulders on roadsides play an important, ifnot irreplaceable, role in providing vehicle operators a safe and effective surface for emergency maneuvers. Additionally, roadside grasses prevent soil erosion, improve sight distance and improve the aesthetic appeal ofthe road.
Bermudagrass (Cynodon dactylon), a low growing, creeping warm-season perennial, is the most commonly found grass on roadsides in Georgia. The low mowing requirement of bermudagrass, combined with its ability to grow over a wide range ofenvironmental conditions, make it the preferred grass species for roadsides in Georgia.
Well-maintained bermudagrass is considered to be highly competitive with weeds. However, certain weed species have the ability to compete with bermudagrass for soil moisture, nutrients and sunlight. Additionally, bermudagrass becomes dormant during the late fall and winter months. As bermudagrass enters dormancy, winter annual weeds emerge and thrive due to the lack ofcompetition from dormant bermudagrass. The presence ofa high population oftallgrowing winter annual weeds decreases the attractiveness ofthe roadside and can also thin stands ofbermudagrass by providing competition during the spring green-up ofbermudagrass.
The Georgia Department ofTransportation (GDOT) currently utilizes a combination of herbicides and mowing to manage vegetation on 120,000 acres ofroadsides. Herbicide costs in 1994 averaged $8.25 per acre, while mowing costs averaged $28.35. Grass roadsides managed by GDOT are mowed an average of 1.8 times per year, and depending upon the location average 3 to 4 herbicide applications per year. The approach ofintegrating the use ofmowing and
herbicides has been successful in reducing the expenses associated with maintaining grass
roadsides in Georgia. . .
Vegetation management programs in Georgia were developed and implemented to gradually eliminate bahiagrass (Paspalum notatum), prevent seedhead production by tall fescue (Festuca arundinacea), and convert the species composition of the roadside to bermudagrass. These programs have been successful; however, information is needed on the efficacy and fit of newly registered herbicides for weed control. Additionally, because certain weed species are tolerant to the current herbicide program, new weed problems have developed. Therefore, additional research is needed to develop control programs for the various weed species that have recently begun to emerge as problem weeds on Georgia roadsides.
Objectives:
(1) To develop new control programs for winter annual and summer annual weeds, and address "new" problem weeds, such as Florida paspalum (Paspalumj/oridanum), musk thistle (Carduus nutans), annual sowthistle (Sonchus spp.) and hemp dogbane (Apocynum cannabiniJm):_' .
2

(2) To develop vegetation management programs that cause minimal injury ("brown-out") to bermudagrass.
(3) To provide consultation to GDOT on present and future roadside vegetation management programs and issues.
(4) Due to the need expressed by GDOT, additional research was conducted on the efficacy of herbicides for weed control in woody ornamentals and wildflowers. This research objective was not included in the original proposal to GDOT.
Since the inception of this project (January 14, 1995),43 weed control experiments have been conducted. A summary of the results is presented for each experiment on pages 7 -22, with the corresponding data located on pages 26 - 206. Refer to the table ofcontents for the page number of each summary and coinciding data. Specific recommendations to GDOT, based largely upon these experiments, are shown on pages 23 - 24.
Methodology
All grass roadside and ornamental weed control experiments were conducted either on GDOT or county roadsides and ornamental beds or on Experiment Station properties. Application methods and dates oftreatment are noted for each experiment. Most data are presented using the format ofthe Pesticide Research Manager (PRM) software. Due to limited field lengths, this software uses a 5 letter code name (the Bayer code) for weed species. For example, the 5 letter code for bahiagrass is PASNO. An abbreviation section which lists the common and scientific name for each Bayer code weed name is shown on page 6.
Weed control and roadside grass and ornamental injury ratings were recorded at various time
intervals following herbicide application on a scale of 0 to 100. For weed control, 0 = no control,
and ioo = complete control ofa problem weed species. For most weed species, a rating of80%
would be considered acceptable control. For either roadside grass or ornamentals, injury was
recorded on a scale of 0 to 100, where 0 = no injury and 100 = complete death of the roadside
grass or ornamental. An injury rating of > 30, would not generally be acceptable in most situations. In some wildflower experiments, either percent (%) stand ratings or wildflower species counts were recorded. Additionally, bahiagrass seedhead suppression ratings are reported
on a scale of 0 to 100, where 0 = no seedhead suppression and 100 = no bahiagrass seedheads
present in plot area.
Data from replicated experiments were statistically analyzed with ANOVA (analyses of variance procedures). LSD (least significant difference) at the 0.05 level was used to compare treatment means.

SUMMARY
Roadside Grass Experiments - 1995
1. Evaluation of Cadre for bahiagrass growth regulation. At the time this experiment was conducted Cadre was the trade name for imazapic, the active ingredient currently being marketed under the trade names of Plateau and Imazapic Applicators Concentrate. Cadre is now registered for use on peanuts. Cadre at all rates evaluated provided2: 83% bahiagrass seedhead suppression at the July 18, 1995 (11 weeks after treatment) evaluation. However, at Cadre rates 2: 0.063 lbs. ai/acre, the stand (density) ofbahiagrass was reduced 2: 20% at this evaluation. Tank-mixes of Cadre with Roundup, pendimethalin, Vanquish, 2.4-n, and Arsenal also effectively reduced bahiagrass growth. This experiment showed that the active ingredient in Cadre, imazapic, can be used to manage bahiagrass growth; however, rates < 0.063 lbs. ai/care should be used unless the objective was to reduce the stand or density ofbahiagrass. Data shown on p. 26.
2. MSMA alternatives on roadsides. This non-replicated experiment was conducted utilizing a GnOT spray truck to evaluate potential replacements to the current GnOT summer herbicide, MSMA. Tank mixtures ofRoundup at rates of 0.25 to 0.375 lbs. ai/acre with MSMA provided better control of crabgrass and yellow foxtail than MSMA applied alone. However, the addition of Roundup to MSMA increased injury to bermudagrass over that obtained by MSMA. Plateau at 0.63 lbs. ai/acre injured bermudagrass more than MSMA at 14 and 30 days after treatment. Weed populations were not uniform; however, it was observed that Roundup at 0.3125 + MSMA at 1.5 lbs. a/acre and Roundup at 0.375 + MSMA at 1.0 Ibs. a/acre effectively controlled hairy fleabane. Data shown on p. 32.
3. Musk thistle control on grass roadsides. This non-replicated experiment showed that
Roundup + Oust + Telar, Garlon 4 + Tordon, and Oust + Telar + Tordon effectively controlled musk thistle and Japanese honeysuckle when applied in mid-March. Roundup + Oust + Telar injured bermudagrass, as expressed as delayed greenup, more than Garlon 4 + Tordon, and Oust + Telar + Tordon. Garlon 4 + Tordon did not injure tall fescue; however, severe injury occurred with Roundup + Oust + Telar and Oust + Telar + Tordon. A combination of Tordon with Garlon 4 or with Oust + Telar provided better blackberry control than Roundup + Oust + Telar. No
herbicide combination effectively controlled trailing dewberry. Data shown on p. 35.
4. Winter weed control on grass roadsides. This experiment was conducted to determine the efficacy of various combinations ofTordon, Garlon 4, Transline and Vanquish in combination with Roundup for winter weed control. Bermudagrass injury was < 22% for all herbicide combinations at the May 16, 1995 evaluation. Fescue control ranged from 50 to 88% at the May 16, 1995 evaluation; however, by June 26, 1995 tall fescue had completely recovered and no injury was apparent. At the June 26, 1995 evaluation, buckhorn plantain (pLALA) was controlled with all herbicide combinations with the exception of Roundup + Vanquish (67% control). Carolina horsenettle (SOLCA) populations were highly variable on this site and control ranged from 43 to 98% at the June 26, 1995 evaluation. Because of the variable Carolina
7

horsenettle populations, no statistically significant difference between treatments were detected. All herbicide combinations effectively controlled horseweed (ERICA). Data shown on p. 37.
Roadside Grass Experiments -1996
5. Eyaluation of Plateau and Oust for winter weed control on grass roadsides. The objective of this experiment was to compare the effect ofPlateau and Oust, applied at high labeled rates, on the spring green-up of roadside bermudagrass when applied during the late fall to early spring time frame. Plateau at 0.094 and 0.156Ibs. ai/acre did not affect the spring green-up of bermudagrass (CYNDA) except when applied on March 14, 1996. In contrast, with exception of Oust applied at 0.046Ibs. ai/acre applied on November 9, 1995, Oust decreased bermudagrass green-up. At the April 26, 1996 evaluation, bermudagrass green-up was still being delayed by Oust applied in mid-November at 0.074Ibs. ai/acre, or when applied at either rate in midDecember, mid-January, mid-February and mid-March. However, by the May 29, 1996 evaluation or approximately 30 days later, bermudagrass had recovered from Oust injury and no delayed green-up was apparent. This experiment showed that Plateau affects bermudagrass green-up less than Oust. Both Plateau and Oust provided acceptable control of wild garlic (ALLVI), except when applied in mid-March. Additionally, both Plateau and Oust controlled Carolina geranium (GERCA). Venus lookingglass (TJDPE) control tended to be higher when Plateau and Oust were applied from mid-December through mid-March than when applied in midNovember. Annual sowthistle (SONOL) was not effectively controlled with Oust. Control of annual sowthistle with Plateau ranged from 47 to 85%. Data shown on p. 41.
6. Evaluation ofR6447 for winter weed control on bermudagrass roadsides. R6447 is an experimental preemergence herbicide being developed by DuPont for use on grass roadsides and other noncropland areas. R6447 at rates that ranged from 0.25 to 0.75 lbs. ai/acre provided good control of wild garlic (ALLVI), excellent control of annual sowthistle (SONOL) and did not affect the spring green-up of bermudagrass. Oust at rates of 0.046 and 0.092Ibs. ai/acre controlled wild garlic, but did not control annual sowthistle. Additionally, Oust at 0.092 lbs. ai/acre decreased the spring green-up of bermudagrass. Data shown on p. 46.
7. Eyaluation ofMON37555 on bermudagrass roadsides. MON37555 is an experimental postemergence herbicide currently under development by Monsanto. The objective of this experiment was to determine the tolerance of bermudagrass and bahiagrass to mid-June applications ofMON37555 applied alone or in combination with Roundup and Plateau. Both bermudagrass (CYNDA) and bahiagrass (PASNO) exhibited acceptable tolerance to MON37555. Injury to these roadside grasses was higher when MON37555 was tank-mixed with Roundup or Plateau than when MON37555 was applied alone. MON37555 provided only short term (34 days) suppression ofbahiagrass seedheads. A tank-mix ofPlateau at 0.063 lbs. ai/acre + MON37555 at 0.03 lbs. ai/acre was highly effective for bahiagrass seedhead suppression. Data shown on p. 49.

8. Efficacy of Thrdon K in Roundup + Oust and Roundup + Telar tank-mixes for winter weed control on bennudagrass roadsides. The objective ofthis experiment was to compare the effectiveness of Tordon K applied in combination with Roundup + Oust or Roundup + Telar to the current GDOT winter weed control standard, Roundup + Oust + Telar, for winter weed control and effect on spring green-up of bermudagrass. All herbicide combinations provided excellent control of Japanese honeysuckle (LONJA), Carolina geranium (GERCA), marsh bedstraw (GALT!), goldenrod spp. (SOOZZ) and horseweed (ERICA). The addition of Oust to various tank mixtures improved the control ofwild garlic (ALLVI). Nodding spurge (EPHNU)
and tropic croton (CVNGS) was controlled by all herbicide combinations except Roundup +
.Tordon. Annual sowthistle (SONOL) was controlled by all herbicide combinations except Roundup + Oust + Telar. No herbicide combination significantly affected the spring green-up of bermudagrass. All herbicides injured tall fescue at the April 25, 1996 evaluation; however, by May 31, 1996 tall fescue had completely recovered and no injury was apparent. Data shown on p.53.
9. Comparisons of commercial mixtures of Roundup. Oust. Telar with additions of Tordon 101M for winter weed control on bermudagrass roadsides. Tordon 101M is a Dow AgroSciences product that contains picloram and 2,4-D. The objective ofthis experiment was to compare the effectiveness ofTordon 101M applied in combination with Roundup + Oust or Roundup + Telar to the current GDOT winter weed control standard, Roundup + Oust + Telar, for winter weed control and effect on spring green-up ofbermudagrass. All herbicide combinations provided equivalent control of Japanese honeysuckle (LONJA), Carolina geranium (GERCA), goldenrod spp. (SOOZZ) and horseweed (ERICA). The addition of Oust to various tank mixtures improved the control ofwild garlic (ALLVI). At the final evaluation on June 27, 1996, only Roundup + Oust + Tordon 101M effectively controlled nodding spurge (EPHNU). Tropic croton (CVNGL) was controlled by all herbicide combinations except Roundup + Tordon 101M and Roundup + Telar +Tordon 101M. Annual sowthistle (SONOL) was controlled by all herbicide combinations except Roundup + Oust + Telar and Roundup + Oust + Telar +Tordon 101M. Prickly sida (SIDSP) control ranged from 43 to 75% and no statistically significant differences in control were detected among the various herbicide treatments. No herbicide combination significantly affected the spring green-up of bermudagrass. All herbicides injured tall fescue at the April 25, 1996 evaluation; however, by May 31, 1996 tall fescue had completely recovered and no injury was apparent. Data shown on p. 59.
10. Winter weed control evaluations on bennudagrass roadsides. The objective of this experiment was to determine if the addition ofVanquish or Gadon 4 to Roundup + Oust + Telar, Roundup + Telar or Roundup + Oust would improve the control of winter broadleafweeds. Due to the spatial variability of Japanese honeysuckle (LONJA) on the experimental site, it was not
possible to collect data for Roundup + Oust + Vanquish and Roundup + Oust + Garlon 4. All
other herbicide combinations effectively controlled Japanese honeysuckle. Good to excellent control of Carolina geranium (GERCA), goldenrod spp. (SOOZZ), marsh bedstraw (GALT!), horseweed (ERICA), tropic croton (CVNGS) and prickly sida (SIDSP) occurred with all herbicide combinations. Compared to the current GDOT winter weed control tank mix of
9

Roundup + Oust + Telar, there was no advantage of tank mixing either Vanquish or Garlon 4 with Roundup + Oust + Telar, Roundup + Telar or Roundup + Oust for the previously mentioned
group of weeds. Roundup + Telar tank mixed with Vanquish or Garlon 4 provided less control of wild garlic (ALLYl) than the other herbicide combinations at the May 25, 1996 evaluation. All herbicide combinations provided equivalent levels of nodding spurge (EPHNU) control. When compared to the current GDOT standard tank mix of Roundup + Oust + Telar, only the tank mix of Roundup + Telar + Vanquish improved the control of annual sowthistle (SONOL). With the exception of annual sowthistle, the use of either Vanquish or Garlon 4 in combination with
Roundup + Oust + Telar, Roundup + Telar or Roundup + Oust did not improve winter broadleaf weed control over that obtained with Roundup + Oust + Telar. No herbicide combination
significantly affected the spring green-up of bermudagrass. All herbicides injured tall fescue at the April 25, 1996 evaluation; however, by May 31, 1996 tall fescue had completely recovered and no
injury was apparent. Data shown on p. 65.
11. Plateau for bahiagrass growth suppression in unimproved turf and roadsides using sequential applications. The objective of this experiment was to determine the length of bahiagrass growth reduction and seedhead suppression from single and sequential applications of Plateau. A single application ofPlateau at 0.048 and 0.063 lbs. ai/acre on May 6, 1996 provided 77 and 80 %, respectively, bahiagrass (PASNO) seedhead suppression on August 28, 1996 (114 days after application). Height decrease, which is a direct reflection ofgrowth reduction, averaged approximately 34% for the two previously mentioned rates of Plateau. Due to the excellent seedhead suppression provided by Plateau at 0.048 or 0.063 Ibs. ai/acre, applied on May 6, no mowing would have been necessary on this site during the summer months. Repeating the Plateau application on July 29, 1996 increased bahiagrass seedhead suppression and vegetative height reduction over that obtained with a single early May application. However, the severe bahiagrass color decrease (injury expressed as yellowing ofbahiagrass foliage) and stand decrease observed on August 28, 1996 indicates that the use of repeat applications of Plateau on bahiagrass during the growing season may not be advisable if bahiagrass is the desired roadside grass. However, in mixed stands ofbermudagrass and bahiagrass, the use of repeat applications of
Plateau would be an effective strategy for reducing bahiagrass infestations. Data shown on p. 73.
12. Plateau for common bermudagrass growth suppression in unimproved turf and roadsides using sequential applications. The objective of this experiment was to determine the tolerance of roadside bermudagrass to single and sequential applications of Plateau during the summer months. The experimental site was located in Pike County and was under severe drought stress during the majority of the duration of the experiment. Bermudagrass (CYNDA) displayed
acceptable tolerance 30% color decrease) to Plateau at the July 22, 1996 (34 days after the
initial application). At this same evaluation Plateau at all rates provided 92 to 100% bahiagrass (PASNO) seedhead suppression. The repeat application ofPlateau was not made until August 19, 1996. Repeating the application ofPlateau improved bermudagrass seedhead suppression on September 20, 1996 when compared to single applications. However, seedhead suppression ranged only from 30 to 36% for the repeat applications ofPlateau. Plateau is more effective in suppressing seedhead emergence on bahiagrass than on bermudagrass. At the September 20,

1996, bahiagrass seedhead suppression ranged from 98 to 100% for both single and sequential applications ofPlateau. This experiment showed that bermudagrass has sufficient tolerance to Plateau to permit either single or sequential (2) applications during the summer months, and that Plateau effectively suppressed bahiagrass seedhead development and vegetative growth. Data
shown on p. 78 .
13. Highway 41/19 winter weed control comparisons. This non-replicated experiment was conducted utilizing a GDOT spray truck to evaluate potential replacements to the current GDOT winter herbicide tank mix, Roundup + Oust + Telar. Percent bermudagrass green-up, tall fescue injury, and the presence (yes) or absence (no) of three weed species were assessed at five randomly selected areas within a specific treatment area. Roundup + Oust + Telar (treatment 1) will be referred to as the GDOT standard for brevity purposes in this summary. Compared to the GDOT standard, Roundup Pro + Tordon (treatment 2) , and Roundup Pro + Telar + Tordon (treatment 3) affected bermudagrass green-up less and injured tall fescue less at 42 days after treatment (DAT). No differences in bermudagrass or tall fescue tolerance was evident by 78 DAT. Roundup Pro + Tordon and Roundup Pro + Telar + Tordon provided better control of sowthistle and prickly lettuce than the GDOT standard. None of these herbicide combinations provided acceptable control ofbuckhorn plantain. Roundup Pro +Telar + Garlon 4 (treatment 4) and Roundup + Telar + Vanquish (treatment 5) affected bermudagrass green-up less and injured tall fescue less than the GDOT standard at 42 DAT. No differences in bermudagrass or tall fescue tolerance was evident by 78 DAT. There was essentially no difference in sowthistle, prickly lettuce and buckhorn plantain control between Roundup Pro + Telar + Garlon and Roundup + Telar + Vanquish and the GDOT standard. Plateau at 9.0 oz. product/acre (treatment 6) and at 4.5 oz. product/acre (treatment 7) decreased bermudagrass green-up more than the GDOT standard at both 42 and 78 DAT. Additionally, Plateau at 9.0 oz. product/acre killed tall fescue (100% injury). At the 4.5 oz. product/acre rate ofPlateau tall fescue injury ranged from 40 to 60 % at 78 DAT. Weed populations were highly variable, and no clear differences in control were readily evident between the Plateau treatments and the GDOT standard. This nonreplicated experiment, in which herbicide treatments were applied with a GDOT spray truck, showed that combinations of Tordon with Roundup Pro, or with Roundup Pro + Telar and combinations of Vanquish or Garlon 4 with Roundup + Telar have less effect on the spring green-up of bermudagrass than the current GDOT standard, and provide better or equivalent control ofsowthistle, prickly lettuce and buckhorn plantain. Data shown on p. 84.
Roadside Grass Experiments - 1997
14. Evaluation of DE-564 (diclosulam) in actiyely-growing bermudagrass. DE-564 is a Dow AgroSciences experimental herbicide that is being investigated for use on grass roadsides. DE564 contains the active ingredient diclosulam, and will probably be registered for use first in peanuts under the trade name of StrongArm. The objective of this experiment was to determine the tolerance of roadside bermudagrass and weed control efficacy ofDE-564 when applied during the summer months. DE-564 injured bermudagrass (CYNDA) less at 11 and 26 days after application (DA-A) than Plateau and Oust. However at 56 DA-A, DE-564 at 52 and 70 g ai/ha
11

injured, as expressed by foliage discoloration, bermudagrass more than Plateau and Oust. In contrast, bermud~grass growth suppression was decreased more by Plateau and Oust than by DE564 at both 56 and 82 DA-A. DE-564 at all rates and Plateau at both rates provided good (>80%) control of marsh bedstraw (GALT!) at 26 DA-A. Oust and MSMA did not control marsh bedstraw. No herbicide effectively controlled buckhorn plantain (pLALA). At 82 DA-A, all herbicides, except Plateau at 105 g ai/ha controlled horseweed (ERICA). Knotroot foxtail (SETGE) and nodding spurge (EPHNU) was not controlled by any herbicide at 82 DA-A. DE564 demonstrated excellent (>90%) of slender copperleaf(ACCGR) and pitted morningglory
(IPOLA) at 82 DA-A. Data shown on p. 88.
15. Evaluation 0(E-564 (diclosulam) for use (or highway ROW weed control and grass release program compared to Roundup. Oust and Telar. DE-564 is a Dow AgroSciences experimental herbicide that is being investigated for use on grass roadsides. DE-564 contains the active ingredient diclosulam, and will probably be registered for use first in peanuts under the trade name of StrongArm. The objective ofthis experiment was to determine the tolerance of roadside bermudagrass and weed control efficacy ofDE-564 when applied in March. The GDOT
winter herbicide tank-mix, Roundup + Oust + Telar, was included for comparison purposes.
Herbicides were applied on March 21, 1997 when bermudagrass was in the 50% green-up growth stage. At 28 DA-A (days after application), DE-564 applied alone affected bermudagrass
(CYNDA) green-up less than Roundup + Oust + Telar, Oust + Telar, and DE-564 combinations
with Roundup. At both 61 and 83 DA-A, no herbicide affected bermudagrass green-up. All herbicides provided excellent control oflarge hop clover (TRFCA) at 28 DA-A. At 61 DA-A,
DE-564 applied alone, or in combination with Roundup, Roundup + Oust + Telar, and Oust +
Telar, effectively controlled tall lettuce (LACCA). Marsh bedstraw was controlled at 61 DA-A
with the previously listed herbicides, with the exception of Oust + Telar which provided only 10%
control. Horseweed (ERICA) was controlled by all herbicides. At 110 DA-A, southern crabgrass
(DIGSP) density was greater in all herbicide plots than in the untreated check. Data shown on p. 93.
16. Evaluation 0(E-564 (diclosulam) in actively-growing roadside bahiagrass. DE-564 is a Do_w AgroSciences experimental herbicide that is being investigated for use on grass roadsides. DE-564 contains the active ingredient diclosulam, and will probably be registered for use first in peanuts under the trade name ofStrongArm. The objective ofthis experiment was to determine the effectiveness ofDE-564 in regulating the growth and seedhead emergence of roadside bahiagrass. DE-564 at all rates injured bahiagrass (PASNO) less at 26 DA-A (days after .
application) than Plateau and Oust. However, at 26 DA-A, DE-564 was ineffective 15%) in
suppressing bahiagrass seedhead emergence. In contrast, Plateau and Oust provided >99% bahiagrass seedhead suppression at 26 DA-A. It was not possible to collect bahiagrass seedhead suppression at 59 DA-A, since the test site was inadvertently mowed by the county roadside department. At 59 DA-A, only Plateau and Oust decreased bahiagrass stand density. This experiment showed that DE-564 would not be an effective herbicide for bahiagrass growth regulation. However, bahiagrass exhibited good tolerance to DE-564 which indicates that this
herbicide could be used for weed control in bahiagrass roadside turf Data shown on p. 97.

17, Evaluation of MON37536 for johnson&rass control in roadside bermudagrass . MON37536 is a postemergence herbicide that is being developed by Monsanto for use on roadside turf Previous research has shown that bermudgrass has excellent tolerance to this herbicide. The objective of this experiment was to determine the effectiveness ofMON37536 for the control ofjohnsongrass. At 56 DA-A, MON37536 at 1.33 oz. product/acre provided the highest level (92%) control ofjohnsongrass. At 56 DA-A, MSMA at 3.0 pts. product/acre provided only 67% johnsongrass control.. MON37536 and MSMA did not control southern crabgrass (DIGSP) at 56 DA-A. The addition ofRoundup Pro at either 8 or 12 oz. product/acre significantly increased the control of southern crabgrass over that obtained with MON37536 or MSMA. This experiment showed that MON37536 is an effective herbicide for johnsongrass control; however, it will be necessary to include low rates of Roundup Pro or another suitable herbicide in order to control southern crabgrass. Data shown on p. 101.
18, Control of winter weeds usin& veteran. Veteran lOG is a granular herbicide that contains 10% dicamba. Veteran 2010 Contains 1.25 and 2.5Ibs. ofdicamba and MCPA, respectively, per gallon of formulated product. The objective of this experiment was determine the efficacy of Veteran and Veteran 2010 for winter weed control on a grass roadside. At 44 DA-A (days after application), Veteran, Veteran 2010 and Roundup + Oust +Telar provided equivalent control of wild garlic (ALLVI), Carolina geranium (GERCA), cudweed spp. (GNAZZ), yellow thistle (CIRHO) and goldenrod spp. (SOOZZ). No differences in bermudagrass (CYNDA) or bahiagrass (PASNO) green-up was observed among these treatments at 44 DA-A. Excellent control oflarge hop clover (TRFCA) and wild lettuce (LACZZ) was observed with all herbicides 70 DA-A. Data shown on p. 104.
19, R6447 tank-mixes for winter weed control on bermudagrass roadsides. R6447 is an experimental preemergence herbicide being developed by DuPont for use on grass roadsides and other noncropland areas. The objective of this experiment was to determine the efficacy of various R6447 tank mixtures for the control ofweeds on a mixed tall fescue, bermudagrass and bahiagrass roadside. For purposes of brevity, weed control data will be discussed for only the 84 and 162 days after application (DA-A) evaluations. R6447 applied alone or in combination with Roundup did not affect the spring green-up of bermudagrass at 59 DA-A. However, Oust, and R6447 + Oust tank-mixes decreased bermudagrass green-up at 59 DA-A. All herbicides moderately to severely injured tall fescue (FESAR) at 59 and 84 DA-A. Oust applied alone, or in combination with R6447, generally injured bahiagrass (PASNO) more than R6447 applied alone or in combination with Roundup. R6447 applied alone did not control goldenrod spp. (SOOZZ) as this weed had already emerged at the time oftreatment on January 27, 1997. Roundup, Oust and tank-mixtures ofR6447 with these two previously mentioned herbicides provided equivalent levels of goldenrod spp. control at 84 DA-A. At 162 DA-A, tank-mixtures ofR6447 with Roundup or Oust provided better control of horseweed (ERICA) than R6447 applied alone. R6447 applied at rates that ranged from 0.125 to 0.5 lbs. ai/acre provided 78 to 97% southern crabgrass (DIGSP) control at 162 DA-A. However, control of knotroot foxtail (SETGE) was poor with R6447 applied alone or in combination with Oust or Roundup. Compared to the untreated check no herbicide affected the density ofbahiagrass, tall fescue or bermudagrass at 162
13

DA-A. Data shown on p. 109.
20. Evaluation of Plateau and Oust for winter weed control on grass roadsides - 1997. The objective of this experiment was to compare the effect ofPlateau and Oust, applied at high labeled rates for two consecutive years on the spring green-up of roadside bermudagrass when applied during the late fall to early spring time frame. Plateau at 0.094 and 0.156 lbs. ai/acre did not affect the spring green-up of bermudagrass (CYNDA) except when applied on March II, 1997 [see CYNDA green-up at 152 DA-A (days after application)]. In contrast, with exception of Oust applied at 0.046 or 0.92Ibs. ai/acre applied on November 20, 1996, Oust decreased bermudagrass green-up at 152 DA-A. At the May 21, 1997 evaluation or 182 DA-A, bermudagrass green-up was still being delayed by Oust applied in mid-January or mid-February at 0.074Ibs. ai/acre, or when applied at either rate in mid-March, and by Plateau applied in midMarch. This experiment showed that Plateau affects bermudagrass green-up less than Oust. However, Plateau applied in mid-March to plots that had received the same treatment the year before affected bermudagrass green-up for a longer period of time than was observed the previous year. This two year experiment showed that high labeled rates of Plateau and Oust could be used for winter weed control on bermudagrass roadsides. However, to avoid delays in bermudagrass spring green-up, Oust at these rates should only be applied in November or December. Plateau could be applied from November through mid-February; however, applications during March should not be used unless some delay in bermudagrass spring green-up is acceptable. Both Plateau and Oust provided acceptable control of wild garlic (ALLYl).. Additionally, both Plateau and Oust controlled Carolina geranium (GERCA). Plateau provided better Venus lookingglass (TJDPE) control than Oust. As was observed the previous year, annual sowthistle (SONOL) was not effectively controlled with Oust. Control of annual sowthistle with Plateau ranged from 57 to 85%. Oust provided better control of horseweed (ERICA) than Plateau at 182 DA-A. MidNovember through mid-January applications ofPlateau were not as effective as Oust applied during the same time frame in controlling common ragweed (AMBEL) at 182-DA-A. However, when applied either in mid-February or mid-March, Plateau and Oust were equally effective in controlling this weed. Data shown on p. 115.
21. Efficacy of the "Weed-Bug" applicator for selective weed control in bermudagrass. The Weed-Bug is a new type of tractor-mounted application equipment that was designed by an Australian company to improve the selective application ofRoundup on grass roadsides. The Weed-Bug uses hydraulically spinning disks with a radial arrangement of porous ropes to uniformly apply Roundup. Wiping height of the spinning disks may also be hydraulically controlled. A non-replicated experiment was conducted on June 3, 1997 with representatives of the Weed-Bug company to evaluate the potential ofthe Weed-Bug for the selective removal of weeds on a grass roadside. A 50% v/v solution of Roundup was used. On July 8, 1997, or approximately 35 days after application (DA-A), and on August 8, 1997, or approximately 65 DA-A, Roundup, applied with the Weed-Bug provided good to excellent control of prickly lettuce, panicum spp., Florida paspalum, hemp dogbane, knotroot foxtail and weeping lovegrass. However, tall fescue was severely injured (> 85%) at both 35 and 65 DA-A. The severe tall fescue injury can be attributed to the fact the experimental sites had not been mowed before
14

treatment, and thus tall fescue foliage and seedhead were contacted by Roundup. Bermudagrass injury ranged from 30 to 80% at 35 DA-A, and from 10 to 75% at 65 DA-A. The slight to severe injury to bermudagrass occurred due to contact of bermudagrass foliage by the spinning disk, and transfer ofRoundup from treated weed foliage to desirable grasses by tractor tires. This nonreplicated experiment showed that Weed-Bug could be used for the control of problem weeds such as hemp dogbane, Florida paspalum and weeping lovegrass. However, careful attention to wiping height of the spinning disks needs to be carefully monitored in order to avoid severe injury to desirable roadside grasses. Data shown on p. 122.
22. Evaluation of Plateau and Roundup Pro for summer weed control on Highway 82. This non-replicated experiment was conducted to evaluate the efficacy of tank-mixtures of Plateau and Roundup Pro for summer weed control on a grass roadside. MSMA at 3.0 pts.lacre, the standard GDOT summer herbicide, was included for comparison purposes. All herbicides were applied with a GDOT spray truck on June 19, 1997. MSMA was reapplied by GDOT personnel on July 25, 1997. Weed control, bahiagrass seedhead suppression, and bermudagrass tolerance was evaluated at 25 days after application (DA-A) on July 14 and at 53 DA-A on August 11, 1997.
Plateau + Roundup Pro tank mixtures and Roundup Pro injured bermudagrass more than MSMA at 25 DA-A. The injury from Plateau + Roundup Pro at 4.0 + 4.0 oz.lacre and Roundup Pro at 8.0 oz.lacre was < 20% and would be acceptable. The injury from other Plateau + Roundup Pro
treatments was 30% which would be marginally acceptable. By 53 DA-A no injury was evident for any herbicide treatment. Two applications ofMSMA provided excellent (> 90%) control of knotroot foxtail at 53 DA-A. However, a single application of Plateau + Roundup Pro at 4.0 +
4.00z.lacre, Plateau + Roundup Pro at 4.0 + 8.0 oz.lacre, and Roundup Pro at 8.0 ozlacre also
provided excellent (> 90%) knotroot foxtail control. No herbicide effectively controlled hairy fleabane. Weed populations were not uniform at the site; however, it was observed at 53 DA-A
that Plateau + Roundup Pro at 4.0 + 8.0 oz.lacre provided 100% bahiagrass seedhead suppression. Data shown on p. 123.
23. Evaluation of Plateau tank-mixes on bermudagrassroadsides. The objective of this experiment was to determine the efficacy ofPlateau tank mixtures with Roundup Pro and Garlon 3A or Transline for winter weed control on a grass roadside. The GDOT standard winter herbicide tank mix, was included for comparison purposes. There was no differences in bermudagrass green-up, wild lettuce (LACCA), and Carolina geranium (GERCA) control among herbicide combinations at 44 DA-A. At 70 DA-A, there was no differences among herbicide combinations for the control of large hop clover (TRFCA) and venus lookingglass (TJDPE). All
Plateau tank-mixtures controlled horseweed (ERICA) to that achieved with Roundup Pro + Oust + Telar at 70 DA-A, with the exception of Roundup Pro + Plateau + Garlon 3A at 0.25 + 0.063 +
0.5 lbs. ai/acre. Plateau tank-mixtures with Roundup Pro and Garlon 3A were not effective in
controlling (pHYCA) at 70 DA-A. Roundup + Oust + Telar and all combinations of Plateau and
Transline provided excellent (> 90%) control of Carolina falsedandelion at 70 and 99 DA-A. At
99 DA-A, control of wild lettuce with all Plateau tank mixtures was equivalent to Roundup Pro + Oust + Telar with the exception of Roundup Pro + Plateau + Transline at 0.25 + 0.032 + 0.045 Ibs. ai/acre. Roundup Pro + Oust + Telar provided 100% control of horseweed at 99 DA-A.
15

Only the tank mixtures of Roundup Pro + Plateau with Transline at a rate ofO.09Ibs. ai/acre
controlled horseweed equivalent to that achieved with Roundup Pro + Oust + Telar. Overall, this
experiment showed that Roundup Pro + Plateau + Transline tank mixtures provide a level of weed control similar to that of Roundup Pro + Oust + Telar. However, Transline should be used at a
rate ofO.09Ibs. ai/acre. Data shown on p. 125.
Roadside Grass Experiments - 1998
24. Hairy fleabane (ERlBO) control in roadside bermudagrass (CYNDA). This experiment was conducted to evaluate herbicides for the control of hairy fleabane (ERIBO). Herbicides were applied in late March to hairy fleabane that was 2 to 3 inches in diameter. All herbicides, with the exception ofRoundup Pro + Sencor, or Roundup Pro + the low rate ofKarmex, provided 2: 85%
hairy fleabane control at all evaluations. The GnOT standard winter treatment of Roundup + Oust or Roundup + Oust + Telar was-as effective as the other herbicides in controlling hairy
fleabane. No herbicide combination effectively controlled Italian ryegrass. However, Roundup
Pro alone or in combination with Oust, Telar, Oust + Telar, Transline, Oust + Transline, or Telar
+ Transline provided 2: 90% suppression ofItalian ryegrass seedheads. Additionally, all
herbicides except Roundup Pro + the low rate of Sencor controlled 2: 80% spiny sowthistle.
Bermudagrass was at the 10% spring green-up growth stage when herbicides were applied. However, no herbicide, including Roundup Pro alone or in combination with herbicides adversely injured bermudagrass. This experiment showed that when applied to hairy fleabane at the 2 to 3 inch diameter growth stage, that several herbicides, including the GnOT standard treatment, will effectively control hairy fleabane. Data shown on p. 133.
25. Summer herbicide programs for hairy fleabane (ERlBO) control.
This experiment was conducted to evaluate early summer herbicide applications for the control of hairy fleabane (ERIBO). Herbicides were applied in late May to hairy fleabane that was 5 to 7
:s inches in height. Common bermudagrass injury was 8% with all herbicides, including Roundup
Pro alone or in combination with other herbicides. Only Garlon 3A provided> 80% control of hairy-fleabane at the June 10, 1998 (12 days after application) evaluation. However, at the June 29 evaluation (31 days after application), Garlon 3A at both rates, Escort at 0.02 lbs. Ai/acre, MSMA + Garlon 3A at 0.5 lbs. Ai/acre, MSMA + Transline at 0.094 lbs. Ai/acre and Roundup Pro with either Garlon 3A or Transline controlled 2: 80% of the hairy fleabane. The previously mentioned herbicides, plus both rates of Transline applied alone also provided> 80% hairy fleabane control at the August 12 evaluation (75 days after application). This experiment showed that early summer applications of GarIon 3A, Transline, MSMA + high rates of Garlon 3A or Transline, and Roundup Pro + Garlon 3A or Transline will provide acceptable levels of hairy fleabane control. Data shown on p. 139.
26. Efficacy of sulfoanilide herbicides for use on grass roadsides. This experiment was conducted to evaluate sulfonanilide herbicides currently being developed by nowAgrosciences for use on grass roadsides. Plateau (imazapic), MSMA and fluroxypyr were also included in this
16

experiment. Herbicides were applied to a grass roadside (mixture of common bermudagrass, tall fescue and bahiagrass) on May 23, 1998. With the exception of Plateau (27%) on May 26, 1998 (13 days after application), no herbicide adversely injured common bermudagrass. Plateau also caused significant injury to tall fescue and bahiagrass at all evaluations. However, Plateau is labeled for the control of tall fescue and bahiagrass and should not be used on grass roadsides unless the management objective is to control these species. Low rates of Plateau are also labeled for suppression ofbahiagrass seedheads. MSMA also caused severe injury to bahiagrass. Only fluroxypyr [a herbicide in the same chemical family as triclopyr (Garton) and Transline (clopyralid)] provided good to excellent control of marsh bedstraw (GALTI). At the July 7, 1998 evaluation (55 days after application), all herbicides except MSMA and the high rate ofDE-498 controlled spotted spurge (EPHNU). However, by August 26 (105 days after application) only DE-570 at 70 gm ai/ha, DE-498 at 35 and 70 gm ailha, and Plateau provided ~ 90% control of spotted spurge. Herbicides that effectively controlled (~85%) prickly sida (SIDSP) were DE564, DE-498, fluroxypyr, DE-511, DE-565 and Plateau. Only DE-564 at the high rate, and fluroxypyr controlled tropic croton (CVNGS). Red morningglory (IPOCC) was controlled (> 85%) by DE-564, DE-570, DE-498 at 70 gm ai/ha, fluroxypyr at 140 gm ai/ha, DE-511, DE-565 and Plateau. Pineweed (HYPGE) was controlled only by fluroxypyr. Data shown on p. 133.
27. Tolerance of crimson cloyer varieties to imazapjc and DE-564. Field observations showed in an earlier grass roadside herbicide trial that crimson clover appeared to be tolerant to D&564. An experiment was conducted in 1998 to evaluate the tolerance of three crimson clover varieties ('Tibbee', 'Dixie' and 'Robin') to DE-564 and Plateau (imazapic). Herbicides were applied on March 19, 1998 to crimson clover in the vegetative growth stage. Herbicides were also applied on April 13 to crimson clover that was in the mid-bloom (Tibbee, Dixie) and full bloom (Robin) growth stage. Both rates ofPlateau severely injured all crimson clover varieties when applied at the vegetative growth stage. At the May 11, 1998 evaluation (81 days after application), Plateau injury ranged from 60 to 96%. This amount of injury would be unacceptable and is quite surprising as Plateau is labeled for use on crimson clover. In contrast, when applied at the vegetative growth stage, injury from DE-564 was:S 13% at any evaluation. Both Plateau and DE-564 injured crimson clover varieties when applied at the mid- to full-bloom growth stage. However, at the May 11 evaluation injury from DE-564 ranged from 7 to 12%, while injury from Plateau ranged from 25 to 27%. Crimson clover seed yield was obtained by harvesting the plots. Plateau applied at the vegetative growth stage severely reduced crimson clover seed yields. In contrast, DE-564 applied at the vegetative growth stage did not significantly reduce crimson clover seed yield. Both Plateau and DE-564 reduced crimson clover seed yield when applied at the mid- and full-bloom growth stage. However, DE-564 reduced crimson clover seed yield approximately 30 to 50% in contrast to the> 95% crimson clover seed yield reduction recorded for Plateau. This experiment showed that crimson clover is more tolerant to DE-564 than to Plateau. Plateau caused severe injury to crimson clover and essentially eliminated seed production. Crimson clover is a reseeding winter annual. DE-564 caused only slight injury to crimson clover when applied at the vegetative growth stage and did not reduce crimson clover seed yield. DE-564, applied at the mid- and full-bloom growth stage injured crimson clover and reduced seed yield more than when applied at the vegetative growth stage. But, relative to
17

Plateau, DE-564 is inherently less injurious to crimson clover. Buckhorn plantain (pLALA) was not effectively controlled with either Plateau or DE-564. Additionally, Plateau was more effective than DE-564 in controlling Italian ryegrass. Data shawn on p. 149.
28. Tolerance of tall fescue (FESAR) to Plateau and DE-564. In north Georgia, tall fescue (FESAR) is an important roadside grass. Similar to common bermudagrass, tall fescue can be overseeded with crimson clover. Research has shown that crimson clover at the vegetative growth stage and common bermudagrass is tolerant to DE-564. This experiment was conducted to determine the tolerance of tall fescue to Plateau (imazapic) and DE-564. Herbicides were applied to established tall fescue at the vegetative growth stage on February 19, 1998. Herbicides were also applied to separate plots on April 13, 1998 when tall fescue was in the seedhead growth stage. Plateau at both rates was more injurious to tall fescue than DE-564. These results were to be expected as Plateau is labeled for the control oftall fescue in roadside bermudagrass. DE-564 at 14.2 glacre was less injurious than at 28.4 glacre to tall fescue when applied at both tall fescue growth stages. Tall fescue density ratings on July 30, 1998 showed that DE-564 at both rates did not reduce tall fescue density. DE-564 was more effective than Plateau in controlling vetch species (VICZZ). Neither herbicide provided acceptable control of buckhorn plantain (pLALA). Both Plateau and DE-564 effectively controlled hop clover (TRFAU). This experiment showed that DE-564 could be used to control weeds in roadside tall fescue. As crimson clover is tolerant to DE-564, this herbicide could also be used on tall fescue roadsides overseeded with crimson clover. Data shown on p. 157.
Wildflowers and Annual Flowers - 1995
29. Evaluation of Prodiamine and Metolachlor in established wildflowers. This experiment was conducted to determine the tolerance of established cornflower (Centaurea cyanus), California poppy (Eschscholzia californica), gaillardia, coreopsis spp., and yarrow (Alchemilla millefolium) to prodiamine (Endurance) and metolachlor (pennant) applied in the spring months. All wildflowers exhibited excellent tolerance to prodiamine and metolachlor. Control ofyellow nutsedg.e (CYPES) with metolachlor ranged from 60 to 80% at the August evaluation. Prodtamine did not control yellow nutsedge, but did provide excellent control of southern crabgrass (DIGSP). This experiment showed that these five established wildflower species were tolerant to prodiamine and metolachlor. Data shawn on p. 161.
30. Tolerance of newly-seeded wildflowers to preemergence herbicides. This experiment was conducted to determine ifprodiamine (Endurance) and metolachlor (pennant) could be applied at the time of seeding wildflowers for the control of weeds. Both herbicides initially reduced the establishment of all wildflower species at the May 5, 1995 evaluation. However, by July 6, 1995, actual stand counts of wildflower species per plot showed that cornflower (Centaurea cyanus), California poppy (Eschscholzia californica), annual gailliardia (Gaillardia pulchella), blackeyed susan (Rudbeckia hirta), scarlet flax (Doom rubrum), and scarlet sage (Salvia coccinea) establishment was not affected by prodiamine at rates that ranged from 0.75 to 1.5 lbs. ai/acre, and to metolachlor at rates that ranged from 2.0 to 4.0 lbs.ai./acre. Prodiamine reduced the
18

establishment ofyarrow (Alchemilla millefolium) approximately 50 to 75%. Metolachlor did not reduce yarrow establishment. Both prodiamine and metolachlor effectively controlled southern crabgrass. Prodiamine did not control yellow nutsedge; however yellow nutsedge control with metolachlor ranged from 57 to 62% at the mid-August evaluation. This experiment showed that certain species ofwildflowers were tolerant to prodiamine and metolachlor at the time of seeding. Data shown on p. 163.
Wildflowers and Annual Flowers - 1996
31. Efficacy of Endurance and Endurance combinations for weed control during wildflower establishment. This experiment was conducted to determine if tank-mixes of sulfentrazone
(sold for use in tobacco as Spartan by FMC), isoxaben (Gallery) and imazapic (Plateau) with prodiamine at 1.5 lbs. ai/acre could be used for weed control during wildflower establishment. In most instances the addition of sulfentrazone, oxyflourfen. isoxaben or imazapic to prodiamine reduced the establishment of California poppy, lanceleaf coreopsis and sulfur cosmos (Cosmos sulphureus). Thus, the use of these herbicides at the time seeding would not be advisable for these species. Data shown on p. 168.
32. Efficacy of Endurance and Pennant for weed control during wildflower establishment. This experiment was conducted to obtain additional data on the efficacy of prodiamine (Endurance) and metolachlor (pennant) applied immediately after seeding wildflowers. Wildflower species that were tolerant to prodiamine at rates that ranged from 0.5 to 0.97Ibs. ai.lacre were baby blue-eyes (Nemophila insignis), California poppy and cornflower. Similar to the 1995 experiment prodiamine severely reduced the establishment of yarrow. Baby's-breath (Gypsophila elegans) and com poppy (Papaver rhoeas) were not tolerant to prodiamine, regardless ofthe rate. Lanceleaf coreopsis stands (Coreopsis lanceolata) were reduced approximately 50% by prodiamine at the rates previously mentioned. California poppy, cornflower and baby's-breath establishment was not reduced by metolachlor at 2.0Ibs. ai/acre. At 4.0 lbs. ai/acre metolachlor reduced the establishment California poppy and baby's-breath. Baby blue-eyes, yarrow, and corn poppy stand establishment was reduced by metolachlor at both 2.0 and"4.0 lbs. ai/acre. No reduction in yarrow establishment was observed in 1995 from metolachlor. Weed population density in this experiment was very low, and no weed control data was recorded. This experiment showed that direct-seeded wildflower species vary in their tolerance to prodiamine and metolachlor. For example, baby blue-eyes, California poppy and cornflower to were tolerant to prodiamine. However, prodiamine severely reduced the establishment ofbaby's-breath, corn poppy, and lanceleaf coreopsis. Data shown on p. 172.
Wildflowers and Annual Flowers - 1997
33. Weed control and tolerance of direct-seeded wildflowers to Endurance. This experiment was conducted to determine if Gallery and Plateau could be tank-mixed with Endurance and used at the time of seeding wildflowers. Unlike that observed in 1995 and 1996, prodiamine at rates that ranged from 0.75 to 1.5 lbs. ai/acre did not affect yarrow establishment. Cornflower,
19

California poppy, annual coreopsis and cosmos also showed good to excellent tolerance to prodiamine at the previously listed rates. The addition of Gallery at 0.38 lbs. ai. acre or Plateau at 0.094Ibs. ai/acre (6.0 oz. product/acre) to prodiamine at 0.97Ibs. ai/acre reduced the establishment ofyarrow, cornflower, California poppy, and annual coreopsis. Prodiamine at all rates provided excellent control ofbroadleaf signalgrass, but did not control yellow nutsedge.
The tank-mix ofprodiamine + Plateau provided excellent yellow nutsedge control; however, the
low tolerance of wildflower species used in this study to Plateau would preclude its use at the time of seeding (establishment). Data shown on p. 175.
34. Tolerance of annual ornamentals to Bas32ran and Mana2e. This experiment was conducted to determine ifBasagran and Manage could be used over-the-top of annual vinca, annual begonia, and annual salvia. Basagran was applied to the same plots on May 12 and May 26, 1997. Manage was applied as a single application on May 12, 1997. Foliage injury was recorded at 14,28 and 42 days after application (DA-A). At 45 DA-A, ornamental above-ground foliage was harvested and dry weights of 6 plants/plot were determined. Annual vinca, annual begonia and annual salvia exhibited only minor injury (:5 21%) to two applications ofBasagran at 2.0 or 4.0 pts./acre. Additionally, Basagran did not reduce the above-ground dry weight of these annual flowers. At 42 DA-A, Manage at both rates caused moderate to severe injury of annual begonia and annual salvia, and dry weights of above-ground foliage was severely reduced at 45 DA-A Annual vinca injury from Manage at 1.33 and 2.67 oz. product/acre was 12.5 and 26.3%, respectively at 42 DA-A Above-ground dry weights of annual vinca were not reduced by Manage. This experiment showed that Basagran could be used over-the-top of annual vinca, annual begonia, and annual salvia for control ofweeds such as yellow nutsedge. In contrast, Manage should only be used over-the-top of annual vinca, as it severely injured annual begonia and annual salvia. Data shown on p. 180.
Woody Ornamentals - 1995
35. Winter annual weed control in Georgia nOT ornamentals. This experiment was conducted to determine the efficacy of preemergence herbicides applied in the fall and spring months'for weed control in an established bed ofjuniper. Herbicides evaluated were Surtlan, Gallery, Snapshot 80DF (a mixture of the active ingredients in Surtlan and Gallery), and Snapshot TG (a mixture of the active ingredients in Treflan and Gallery). No herbicide injured established
junipers. At the April 4, 1995 evaluation, Gallery, Surtlan + Gallery, and the Snapshot
formulations provided good control ofvetch spp. Carolina geranium control was acceptable (>80%) for all herbicides except Surtlan at 2.25 lbs. ai/acre and Gallery at 1.0 lbs. ai/acre. No herbicide effectively controlled goldenrod spp. However, this weed was established at the time of treatment and control would not be expected with these preemergence herbicides. At the August evaluation, all herbicides except Gallery, provided good control of yellow foxtail and crabgrass spp. At this same evaluation only Surtlan at 3.0 lbs. ai/acre applied alone or with Gallery at 1.0 lbs. ai/acre and Snapshot GR at 5.0 lbs. ai/acre provided 2: 90% control of nodding spurge. Data shown onp. 184.
20

Woody Ornamentals - 1996
36. A comparison of Surtlan + Princep ys. Derby for winter weed control in Andorra juniper. This non-replicated experiment was conducted to evaluate the efficacy of a late August
applioation ofSurflan + Princep and Derby [a granular formulation of metolachior (4%) and
simazine (1%)] for winter annual weed control in established 'Andorra' juniper. Derby and Surtlan + Princep provided 95% control of prickly lettuce at 7 months after treatment (MAT). Overall, Derby provided higher levels of control of common chickweed, vetch. spp and henbit at 7 MAT. Andorra juniper was not injured by these herbicides. Derby is no longer commercially available. However, the active ingredients in Derby, metolachlor and simazine, are available for use on roadside ornamentals under the trade names of Pennant and Princep, respectively. Data shown on p. 188.
37. Evaluation of Derby and OHrr for winter weed control in Andorra juniper. This nonreplicated experiment was conducted to evaluate the efficacy of a late August application of Derby [a granular formulation ofmetolachlor (4%) and simazine (1%)] and amI [a granular formulation of oxyfluorfen (2%) and pendimethalin (1%)] for winter annual weed control in established'Andorra' juniper. At 4.5 months after treatment (February 21, 1996), no injury was observed on Andorra juniper. Populations of common chickweed and henbit in the untreated check area were very low and averaged only a 1.0% ground cover and it was not possible to collect weed control data. The August application of4 inches of hardwood mulch by GDOT personnel provided excellent control of these two weeds in the untreated check area. Data shown on p. 190.
38. Eyaluation of OBIT for winter weed control in PUtzer juniper. This non-replicated experiment was conducted to evaluate the efficacy ofa late August, 1995 application of OHII [a granular formulation of oxyfluorfen (2%) and pendimethalin (1%)] for winter annual weed control in established 'Pfitzer' juniper. At 4.5 months after treatment (MAT), no injury was observed on Pfitzer juniper. No weeds were present in the area treated with 000 or the untreated check area. At 7.0 MAT (April 2, 1996), 000 provided 95% control of hairy bittercress, Carolina geranium and Vetch spp. Weed populations at the site were very low due to the September application of hardwood mulch by GDOT personnel. Data shown onp. 191.
39. Efficacy of August applications of preemergence herbicides in woody ornamentals. This experiment was conducted to evaluate the efficacy of a late August, 1995 application of Surflan,
Gallery, Princep, and tank-mixes ofSurflan + Gallery or Surflan + Princep for winter annual weed
control in established 'Andorra' juniper. No herbicide injured Andorra juniper. Weed populations were not sufficiently high enough on this site to rate until April 2, 1996. All herbicides provided excellent (>90%) control of prickly lettuce, common chickweed, and vetch spp. on April 2, 1996. Data shown on p. 192.
40. Winter weed in Georgia DOT ornamentals - second year. This experiment was a continuation of Experiment 30 and was conducted to determine the efficacy of preemergence
21

herbicides applied in the fall and spring months for weed control in an established bed ofjuniper. Herbicides evaluated were Surflan, Gallery, Snapshot 80DF (a mixture of the active ingredients in Surflan and Gallery), and Snapshot TG (a mixture of the active ingredients in Tretlan and Gallery). These herbicides were applied to the same plots on September 13, 1994, February 24, 1995 and September 20, 1995. Only data from the April 2, 1996 evaluation will be discussed. No herbicide injured established junipers on April 2, 1996 (data not shown). Thus, this experiment showed that junipers were tolerant to multiple applications of preemergence herbicides over a 12 month period of time. All herbicides provided 2: 80% control of vetch spp.
on April 2, except Gallery at 1.0 lbs. ai/acre, Surflan + Gallery at both rates, and Snapshot DF at
3.0 lbs. ai/acre. Carolina geranium control was >80% for all herbicides except Gallery at 1.0 lbs. ai/acre, and Surflan + Gallery at 3.0 and 1.0 lbs. ai/acre, respectively. Data shown on p. 194.
Woody Ornamentals - 1997
41. Effect of fall preemergence herbicides on yellow n"tsedge control in ornamentals. This experiment was conducted iffall applications ofsulfentrazone (sold for use in tobacco as Spartan by FMC) and metolachlor (pennant) would control yellow nutsedge the following spring. 'Clarissa' holly was tolerant to both herbicides at all evaluations. However, yellow nutsedge was not effectively controlled by fall applications of either sulfentrazone or metolachlor. Data shown onp.197.
42. Efficacy of fall + winter preemergence herbicides for winter weed control in roadside ornamentals. This experiment was conducted to determine if a mid-winter (January) application of preemergence herbicides was necessary to control winter annual weeds following a fall
application of the same herbicides. Surflan, Gallery, Princep, Surflan + Gallery and Surflan +
Princep were applied as a single application in in September 1996, or as repeat application to the same plots in September 1996 and January 1997. 'Clarissa' holly was tolerant to all herbicides. At 225 days after application (DA-A), Surflan at 4.0 lbs. ai/acre applied in September and January provided better annual sowthistle (SONOL) control than when applied only in September.
However, September applications of all other herbicides were as effective as September + January
appli~tions in controlling annual sowthistle. There was no advantage (in terms of increased control) in the control of prickly lettuce (LACSE) from reapplying the herbicides in January compared to a single September application. Yellow nutsedge (CYPES) was not controlled by
any herbicide. This experiment showed that September + January applications of the same
preemergence herbicide generally did not increase control of weeds obtained with only a September application of preemergence herbicides. Data shown on p. 200.
43. Fall preemergence herbicide combinations for roadside ornamentals. The objective of this experiment was to determine the efficacy of fall applied preemergence herbicides for winter annual weed control in 'Clarissa' hollies. No herbicide injured Clarissa holly at any evaluation. All herbicides provided excellent control of Carolina geranium (GERCA) and prickly lettuce (LACSE). Vetch. spp. control was variable and there was essentially no statistically significant differences in control at either 167 or 225 days after application (DA-A). No herbicide provided control of yellow nutsedge (CYPES) at 225 DA-A. Data shown on p. 203.

RECOMMENDATIONS TO GEORGIA DOT
(Not listed in priority order)
1. Imazapic (Imazapic Applicators Concentrate, Plateau) was found to be a suitable alternative herbicide to MSMA. Depending upon the rate, imazapic may be used to control and/or suppress bahiagrass in common bermudagrass roadsides. Additionally, imazapic, at low rates (2.0 to 3.0 fl. oz./acre), is highly effective for regulating the growth (foliage and seedhead development) of bahiagrass. With the introduction of imazapic, GDOT should consider the use of bahiagrass as the preferred roadside grass on dry, sandy sites.
2. Numerous herbicide mixtures for winter weed control were compared to the current GDOT
standard of Roundup Pro + Oust + Telar. No herbicide mixture provided significant weed control
advantages over the current GDOT standards. GDOT should continue to use present standard weed control mixture; however, the inclusion oftriclopyr (Garlon 3A), clopyralid (Transline) or dicamba (Vanquish) with Roundup Pro alone or Roundup Pro + Oust should be utilized as components of a long-term herbicide rotation management strategy. For example, Roundup Pro + Oust + Transline (or Vanquish or GarIon 3A) should be used on a 1 in 3 or 4 year herbicide rotation strategy.
3. Several effective herbicide combinations can be used for the control of hairy fleabane. Late March applications ofRoundup Pro + Oust, Roundup Pro + Oust + Telar, Transline alone or in
combination with Roundup Pro, Oust, Telar, Roundup Pro + Oust or Roundup Pro + Telar
effectively control hairy fleabane with no effect on common bermudagrass spring transition. Late May herbicide applications to hairy fleabane were not as effective as March applications. Herbicides applied in late May that provided 80% hairy fleabane control 75 days after applications
were Garlon 3A, Transline, MSMA + Garlon or Transline, and Roundup Pro + Garlon or
Transline. The current GDOT summer-herbicide, MSMA, does not control hairy fleabane.
4. DE-564, a low rate sulfonanilide postemergence herbicide being developed for roadside grass use, ~as identified as a viable herbicide option for weed control in common bermudagrass, tall fescue, and crimson clover. Research showed that 3 different varieties of crimson clover treated at the vegetative growth stage (mid-March) had outstanding tolerance to DE-564. Imazapic, while labeled for this use, was highly injurious to crimson clover and essentially prevented crimson clover seed production. This research clearly showed that a herbicide program could be developed with DE-564 that would enable the reintroduction of crimson clover on GDOT roadsides. However, this herbicide is not currently labeled as of October, 1998 for this use. However, Dow AgroSciences is highly interested in pursuing a federal registration for this use. Additional research is need to identify tank-mix partners for DE-564 that would control Italian ryegrass.
5. GDOT should consider the use of preemergence herbicides such as Snapshot TG, OHIIor Rout on woody ornamentals, particularly in the first five years after planting. The previously mentioned herbicides are granular formulations which facilitates application by GDOT personnel. Four experiments were conducted to evaluate the use of preemergence herbicide applied at the
23

time of seeding wildflowers. Wildflower species tolerant to Endurance applied immediately after seeding included cornflower, California poppy, annual gailliardia, blackeyed susan, scarlet flax, scarlet sage, baby blue-eyes, annual coreopsis, and cosmos. Non-tolerant species to Endurance were yarrow, baby's breath, corn poppy, and lanceleafcoreopsis. The use ofa preemergence herbicide applied at the time of seeding is desirable. However, the use of a preemergence herbicide should be limited only to seed mixes that contain tolerant wildflower species. Additional research on wildflower species tolerance to preemergence herbicides is needed. 6. A selective glyphosate applicator, Weed-Bug, was identified that could be used for the control of hemp dogbane and other tall growing weeds such as vaseygrass and Florida paspalum. However, wiping height must be carefully monitored or severe injury to roadside grasses will occur. 7. Although it was not an objective of this study, GnOT should equip all spray trucks with herbicide injection systems. The use of herbicide injection systems would enable the operator to spot spray infestations of problem weeds such as hemp dogbane with an effective herbicide. Otherwise, it will be necessary for GnOT personnel to hand spray infestations of weeds that are not controlled by herbicide mixtures used on a wide-scale basis. Other advantages of herbicide injection spray trucks include: a) reduced exposure by operators during mixing and loading, b) precise herbicide applications, and c) enable the operator to stop spraying one or more herbicides that may be injurious to adjacent non-GnOT vegetation but still make an application of a noninjurious herbicide. Herbicide injection systems tied to an on-vehicle computer will also enable GnOT to automatically record herbicide application information.

TRIAL COMMENTS Seedheads just starting to emerge in untreated plots. Seedheads emerged only in untreated check. Centipedegrass (ERLOP) very tolerant to all rates ofPlateau. Carpetgrass (MOLVE) intermediately tolerant Centipede and Carpetgrass showed excellent tolerance to all rates ofPlateau. No seedhead suppression on Carpetgrass was observed. Injwy to Bahiagrass from Plateau may have released Carpetgrass and Centipedegrass. The following plots have Carpetgrass with seedheads and Centipedegrass: Plot # 105, 106, 201 206,301 - 304, and 306. The following plots have released Carpetgrass and Centipcidegrass: Plot # 102 - 106, 20 I, 202, 204, 206,301 - 304.

TREATMENT APPLICATION COMMENTS 3-9-98: Not rated on this date, since application had not yet been made. 4-1-98: Not rated on this date, since application had not yet been made.
Plateau at both rates caused severe stunting and necrosis to Crimson Clover (TRFIN).

TREATMENT APPLICATION COMMENTS DE-564 injury was stunting Clover. Italian Ryegrass (LOLMU) in rep.3 only. 4-23-98:Photographs made ofall treatments in 3rd rep. Plateau (mid-bloom treatments only) caused light colored (greenish yellow to white) flower color at tip ofseedheads on Tibbee. Only a few plants in DE-564
treatments (mid-blooom series only) showed this effect 5-12-98:Sprayed Paraquat at 2 ptJac over all of plots to dessicate clover hor harvesting seed.

A COMPARISON OF SURFLAN + PRINCEP vs. DERBY FOR WINTER WEED CONTROL IN ANDORRA JUNIPER
Tim R. Murphy, Extension Weed Scientist

A non-replicated demonstration was conducted to evaluate the effectiveness of Derby [a granular formulation ofmetolachlor (4%) and simazine (1%)] and a tank-mix ofSurflan + Princep for winter weed control in 'Andorra' juniper.

Treatment particulars were:

Location: Interstate 20 west ramp to Capitol Avenue, Atlanta

Plot Size:

Approximately 200 ft. by 80 ft. Planting was located on a 40% slope adjacent to the interstate.

Cultivar: Andorra juniper

Cultivar Growth Stage: Established, 3 ft. diameter, 1 to 2 ft. mulched area between plants

Application Method:

Derby - hand-held rotary spreader
Surflan + Princep - applied at 25 gpa, with a 5 ft. spray boom
equipped with 11004 nozzle tips.

Herbicide Rate:

Derby - 4.0 lbs. ai/acre metolachlor + 1.0 lb. ai/acre simazine
Surflan 4AS - 4.0 lbs. ai/acre + Princep 4L - 1.0 lb. ai/acre

Application Date:

August 30, 1995

Environmental Conditions: Air temperature - 90 F. Soil temperature - 84 F. Soil moisture - good Sun - bright Wind speed - 0 mph

Mulch Cover:

Site was mulched by GA DOT personnel in September 1995 with 4 inches of shredded hardwood.

CONCLUSIONS:

No herbicide injured Andorra juniper when evaluated at 4.5 and 7.0 months after treatment (data not shown). Weed control data is shown in Table 1.

Evaluation of Derby and OHII for Winter Weed Control in Andorra Juniper
Tim R. Murphy, Extension Weed Scientist

A non-replicated demonstration was conducted to evaluate Derby [a granular formulation of metolachlor (4%) and simazine (1%)] and OIDI [a granular formulation of oxyfluorfen (2%) and pendimethalin (1 %)] for weed control and phytotoxicity to 'Andorra' juniper.
Treatment particulars were:

Location: Interstate 20 east exit to Interstate 75/85 north, Atlanta

Plot Size: Approximately 8,000 sq. ft. for OIDI site; 6,000 sq. ft. for Derby treatment

Cultivar: Andorra juniper

Cultivar Growth Stage:

Established, 12 to 18 inches tall; 3 ft. diameter, 1 to 2 ft. mulched (shredded hardwood bark) area between plants

Application Method:

Hand-held rotary spreader

Herbicide Rate:

2.3 pounds OIDI per 1,000 square feet (equal to 2.0 lbs. ai/acre
oxyfluorfen + 1.0 lb. ai/acre pendimethalin)
2.3 pounds Derby per 1,000 square feet (equal to 4.0 Ibs. ai/acre metolachlor + 1.0 lb. ai/acre simazine

Application Date: August 30, 1995

Environmental Conditions:

Air temperature - 88 F. Soil temperature - 84 F. Soil moisture - good Sun - bright Wind speed - 0 mph

CONCLUSIONS: At 4.5 months after treatment (February 21, 1996), no injury was observed on Andorra
juniper. Weed populations in the untreated check area were very low and averaged only 1.0% ground cover. Both Derby and OIDI were estimated to provide 99% control of henbit and common chickweed. The August application of 4 inches of hardwood mulch was also providing excellent control of these two weeds in the untreated check area.

EVALUATION OF OHII FOR WINTER WEED CONTROL IN PFITZER JUNIPER
Tim R. Murphy, Extension Weed Scientist

A non-replicated demonstration was conducted to evaluate OHII [a granular formulation of oxyfluorfen (2%) and pendimethalin (1%)] for weed control and phytotoxicity to 'Pfitzer' Jumper.

Treatment particulars were:

Location: Boulevard exit off of Interstate 20 east, Atlanta

Plot Size: Approximately 400 ft. by 30 ft.

Cultivar: Pfitzer juniper

Cultivar Growth Stage: Established, 2 to 6 ft. tall, 1 to 2 ft. mulched area between plants

Application Method:

Hand-held rotary spreader

Herbicide Rate:

2.3 pounds OHII per 1,000 square feet (equal to 2.0 lbs. ai/acre oxyfluorfen + 1.0 lb. ai/acre pendimethalin)

Application Date: August 30, 1995

Environmental Conditions:

Air temperature - 85 F. Soil temperature - 75 F. Soil moisture - good Sun - bright Wind speed - 0 mph

Mulch Cover:

Site was mulched by GA DOT personnel in September 1995 with 4 inches of shredded hardwood.

CONCLUSIONS:
At 4.5 months after treatment (February 21, 1996), no injury was observed on Pfitzer
juniper. No weeds were present in area treated with OHII or the untreated check area. At 7.0
months after treatment (April 2, 1996), amI did not injure Pfitzer juniper. At this evaluation,
percent weed cover in the untreated check averaged: hairy bittercress - 10%, Carolina geranium -
5%, vetch spp. - 5%. Over the entire test site, amI provided an estimated 95% control of these
weeds. The September application of mulch probably decreased weed emergence in the untreated
check area.
