16. Abstract

Currently, exotic species are the onlychoice in the Georgia Department of Transportation (GDOT) specifications for grassing

non-mowable slopes, mowable slopes, and areas outside the clear zone. Establishing and maintaining native plants in

targeted areas along the right of way would allow GDOT to provide a more sustainable approach to right of way

management, reduce the quantityof invasive and exotic species, and reduce maintenance costs.

Eight experiments with native grass establishment, maintenance, and release were performed over a three year period. From

these experiments it was determined that establishment of native grasses, such as broomsedge (Andropogon virginicus),

would be difficult to establish from seed. According to the data, a far better approach would be to attempt to shift the

population of native grasses with herbicides.

EXECUTIVE SUMMARY The objectives of this research was to (1) determine whether it might be possible to
establish broomsedge (Andropogon virginicus) in place of the current exotic species specified for erosion control purposes and for treatment on non-mowable slopes of less than 3:1, and (2) to establish a method of removing and/or reducing non-native vegetation located outside the clear zone on mowable areas of 3:1 or flatter; methods which may allow native grasses and/or wildflowers to establish.
The work included three experimental approaches. The first approach was native grass release with herbicides. In these experiments, areas with established populations of native grasses were treated with various herbicides to determine if you could increase the native grass cover simple with herbicide treatments. None of the experiments provided good control of exotic grass species with a single application of select herbicides. The second approach was vegetation management at the time of seeding broomsedge (Andropogon virginicus). In these experiments select herbicides were chosen to determine the best application timing for weed control in seeded broomsedge. Do to the extremely dry summers the past 3 years, reliable information is difficult to attend for these experiments. The final approach was to determine the best herbicide for vegetation management in newly germinated broomsedge. In these experiments herbicides were applied after the germination of broomsedge (3 to 4 leaf). Due to an extremely dry seasons, little to no broomsedge germinated. Little information was obtained from this experiment.

INTRODUCTION:
Currently, exotic species are the only choice in the Georgia Department of Transportation (GDOT) specifications for grassing non-mowable slopes, mowable slopes, and areas outside the clear zone. In reference to the Federal Highway Administration's Guidance on Invasive Plants and the President's Executive Order on native plants, the GDOT is looking for ways to encourage and foster the use of regionally native plants in its construction and maintenance programs. Establishing and maintaining native plants in targeted areas along the right of way would allow GDOT to provide a more sustainable approach to right of way management, reduce the quantity of invasive and exotic species, and reduce maintenance costs.
OBJECTIVES:
To determine which native plants (grasses and/or wildflowers) might be used with or in place of the current exotic species specified for erosion control purposes and for treatment on non-mowable slopes of less than 3:1.
To establish (1) a method of removing and/or reducing non-native vegetation located outside the clear zone on mowable areas of 3:1 or flatter; and (2) methods which may allow native grasses and/or wildflowers to establish.
SIGNIFICANCE OF RESEARCH TO GEORGIA DOT:
This research will help guide GDOT on how to use and re-introduce native species, such as native grasses and wildflowers in a cost effective and ecologically sound approach in its construction and maintenance programs. The research may also discover possible ways of effectively controlling unwanted vegetation in established areas of native species.
WORK PLAN:
All work was completed at the University of Georgia research farms located at Griffin, GA. Eight experiments were performed over a three year period. The principle vegetation in these established areas include invasive non-native herbaceous plants such as bermudagrass (Cynodon dactylon), bahiagrass (Paspalum setaceum), and tall fescue (Festuca arundinacea). Experiments were applied, seeded (if necessary), and rated. Seeded experiments were planted with the native grass broomsedge (Andropogon virginicus). Depending on experiments, areas were evaluated for percent control, percent re-growth of non-native vegetation, percent growth of native vegetation among existing non-native vegetation, percent re-growth of useful natives from seed banks, and percent broomsedge cover. In general, evaluations were performed at 4, 8, 12, 24, and 52 weeks.
Since the inception of this project (June 2005), 8 experiments have been conducted, beginning in 2006. Refer to the table of contents for the page number of each summary and coinciding data. Specific recommendations toGDOT,basedlargelyupon these experiments, are shown on pages 10.

METHODOLOGY: Application methods and dates of treatment are noted for each experiment. Most data are presented
using the format of the Agricultural Research Manager (ARM) 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 7.
Grass control ratings were recorded at various time intervals following herbicide application or seeding and were rated on a scale of 0 to 100. For weed control, 0 = no control, and 100 = complete control. An 80% control of undesirable species undesirable species would be considered acceptable control. Injury of desirable grasses species (i.e. broomsedge (Andropogon virginicus)) was recorded on a scale of 0 to 100, where 0 = no injury and 100 = complete death of the grass. An injury rating of greater than 30, would not generally be acceptable in most situations.

SUMMARIES OF NATIVE GRASS STUDIES
Native Grass Studies - 2006
1. Vegetation Management at the time of seeding broomsedge (Andropogon virginicus) (establishment All treatments applied before seeding). The goal of this experiment was to determine if herbicides applications could help the establishment of broomsedge at the time of seedling. We were particularly interested in imazapic, the active ingredient currently being marketed under the trade name of Plateau and as a mix in the product Journey (both products are available for roadside weed control). Due to an extremely dry season, little to no broomsedge germinated. Little information was obtained from this experiment. Crabgrass had taken over the entire study by the 28 weeks after treatment (WAT) rating. Data shown on pp. 11-13.
2. Vegetation management applied when broomsedge is 3 to 4 leaf stage (New site Planted into glyphosate killed vegetation). The goal of this experiment was to determine if herbicide applications could help the establishment of broomsedge after germination (3 to 4 leaf). We were particularly interested in imazapic, the active ingredient currently being marketed under the trade name of Plateau and as a mix in the product Journey (both products are available for roadside weed control). Due to an extremely dry season, little to no broomsedge germinated. Little information was obtained from this experiment. Crabgrass had taken over the entire study by the 28 WAT rating. Data shown on pp. 14-15.
3. Pre and post vegetation in newly established native plantings (Management). The goal of this experiment was to determine if herbicide applications could help the establishment of broomsedge after germination (2 to 4 weeks after germination). We were particularly interested in imazapic, the active ingredient currently being marketed under the trade name of Plateau and as a mix in the product Journey (both products are available for roadside weed control). Due to an extremely dry season, little to no broomsedge germinated. Little information was obtained from this experiment. Crabgrass had taken over the entire study by the 28 WAT rating. Data shown on pp. 16-17.
4. Native grass release with herbicides. This experiment was designed to help determine if a single application of glyphosate, imazapic, or glyphosate / imazapic combinations could help shift or release already established native grasses. None of the applications provided good control of bermudagrass or tall fescue, and none of the treatments caused injury symptoms greater than 22% to broomsedge. One of the critical issues uncovered by this experiment is that johnsongrass populations would be released by reducing populations of other competitive grasses such as bermudagrass. Other products, such as sulfosulfuron (OutriderTM) would have to be utilized in order to control such invasive grasses. Data shown on pp. 18-20.

Data shown on pp. 21-26.
2. Native grass release with herbicides. This experiment was designed to help determine if a single application of glyphosate, imazapic, or glyphosate / imazapic combinations could help shift or release already established native grasses. None of the applications provided good long term control of bermudagrass or tall fescue with a single herbicide application. None of the treatments caused injury symptoms greater than 20% to broomsedge. As with the 2006 study, johnsongrass populations would be released by reducing populations of other competitive grasses such as bermudagrass. Other products, such as sulfosulfuron (OutriderTM) would have to be utilized in order to control such invasive grasses. Data shown on pp. 27-29.

1. Vegetation Management at the time of seeding broomsedge (Andropogon virginicus) (establishment All treatments applied before seeding). The goal of this experiment was to determine if herbicide applications could help the establishment of broomsedge at the time of seedling. We were particularly interested in imazapic, the active ingredient currently being marketed under the trade name of Plateau and as a mix in the product Journey (both products are available for roadside weed control). Due to an extremely dry season, little to no broomsedge germinated until mid to late fall. Little information was obtained from this experiment. Crabgrass had taken over the entire study by the 28 WAT rating. Data shown on pp. 30-32.
2. Native grass release with herbicides. This experiment was designed to help determine if a single application of glyphosate, imazapic, or glyphosate / imazapic combinations could help shift or release already established native grasses. None of the applications provided good long term control of bermudagrass or tall fescue with a single herbicide application (less than 13%). Data shown on pp. 33-34.

RECOMMENDATIONS TO GEORGIA DOT (Not listed in priority order)
1. The use of broomsedge (Andropogon virginicus) as a replacement for standard turfgrasses (i.e. bermudagrass, bahiagrass, etc.) would be difficult. In situations where turfgrass is needs to be seeded, broomsedge is a poor choice. The seed is expensive, hard to sow, and special equipment is required for proper seeding. The germination window is longer than for standard turfgrasses, and seeding times need to be delegated to rainy periods in the Southeast (November to February). 2. A more logical means of increasing the percent cover of broomsedge (and other native grasses), would be to utilize multiple applications of imazapic (PlateauTM) to help shift existing populations of bahiagrass, bermudagrass and tall fescue to native type grasses. Sequential applications of imazapic applied at 6.0 to 12.0 fl. oz./acre, is highly effective at controlling non-native type grasses (i.e. bermudagrass, bahiagrass, and tall fescue), and allowing native type grasses to thrive. 3. Although minor damage can occur, sequential applications of imazapic applied at 6.0 to 12.0 fl. oz./acre can also be utilized for weed control in broomsedge at early growth stages. However, other herbicides would have to be utilized to control annual grasses (i.e. crabgrass) when trying to establish native type grasses. 4. One of the worst invasive species encountered in many of the experiments was johnsongrass (Sorghum halepanse). If this grass is encountered during establishment of native type grasses, aggressive steps should be taken to control and eliminate the infestation. The herbicide sulfosulfuron (OutriderTM) has been temporarily released on a year by year basis as a Section 18 in the state of Georgia. Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizes EPA to allow an unregistered use of a pesticide for a limited time if EPA determines that an emergency condition exists. Sulfosulfuron provides excellent selective control of johnsongrass in many turfgrass species.
