*Application methods on each site will vary depending on species density, size, and chemical used. For example, one acre may have 3 different species to treat, so you may have 3 different applications and/or methods
Environmental Protection Agency (EPA) approved herbicides will be used. The herbicide concentration applied per acre must adhere to and not exceed the label directions for the appropriate techniques used by the applicator. Contractor will apply herbicide at a sufficient interval and concentration to meet or exceed the kill rate on target NNIS infestations.
Kudzu The methods of control for kudzu shall include the application of a clopyralid herbicide using the foliar spray method with a water soluble surfactant. Spray all vines to the point of runoff and climbing vines with TranslineTM as a 0.5-percent solution in water (2 ounces per 3-gallon mix). Spray all climbing vines as high as possible. Cut large vines and immediately apply the herbicide to the cut surfaces in dilutions as specified on the herbicide label. Inert dye (blue) provided by the contractor shall be added into all herbicide mixes for ease of inspection. Treat during the months of July thru September.
In riparian areas, the methods of control for kudzu shall include the application of a glyphosate herbicide with an aquatic label using the foliar spray method with a 2 percent solution in water (8 ounces per 3 gallon mix) with a surfactant during the growing season. Spray all vines to the point of runoff and climbing vines with a solution of glyphosate with a water soluble surfactant. Spray all climbing vines as high as possible. Cut large vines and immediately apply the herbicide to the cut surfaces. Inert dye (blue) provided by the contractor shall be added into all herbicide mixes for ease of inspection. Treat during the months of July thru September.

Oriental bittersweet The methods of control for oriental bittersweet shall include the application of triclopyr herbicide in water with a surfactant to freshly-cut stumps of plants greater than or equal to 6 feet in height or to the foliage of plants less than 6 feet in height. The contractor shall cut oriental bittersweet plants greater than or equal to six feet in height to the ground without covering other live NNIS plants then immediately and fully apply a 25-percent solution (32 ounces per 1-gallon mix) of Garlon 4 to the cambium layer of the freshly-cut stumps. The contractor shall completely spray to saturation all green foliate on oriental bittersweet plants less than six feet in height with Garlon 4 as a 3-percent solution. Inert dye (blue) provided by the contractor shall be added into all herbicide mixes for ease of inspection. Treat during the months of July thru October.
