------- 122 W VOLUMEWEED AND BRUSH APPLICATIONS WITH THE THINVERT® SYSTEM R. R. Johnson and J. E. Waldrum 1 ABSTRACT The Thinvert Application System utilizes the combination of a thin invert emulsion with a unique new nozzle design to produce small uniform droplets of pesticid sprays. These small uniform droplets permit the accurate applicat'on of herbicides to control many invasive, exotic plant species with little or no exposure to desirable vegetation in natural plant areas, wildlife habitat, environmentally sensitive areas, or landscaped areas. Various availab e nozzle configurations will apply spray patterns as narrow as two to three i ches or as wide as 20 feet, at total spray volumes of 3 to 5 gallons per acr These low volumes allow vegetation managers, wildlife managers, or landsca ers to apply herbicide sprays extensively and economically using backpac sprayers, ATV's equipped with small electric spray units, or with other v hicles that produce minimum physical disturbance to the spray site. Si ce numerous herbicides and herbicide combinations are available which will co trol many undesirable invasive exotic plant species, an application techniq e which will control these exotics with low impact application equipme t, accurate placement, and control of spray drift and evaporation can be a va uable environmental management tool. Beginning in 1991, applications of appr priate herbicides were made to non-native plant species to determine whether applications of these herbicides using the Thinvert Application System would p ovide control of problem non-native species, and to observe effects on non-tar et vegetation. Since product labels may provide rate per acre or spray c ncentration recommendations, efforts were made to reproduce the rate per acr recommendations. Because Thinvert applications apply less total spray v lume, spray concentration recommendations were increased about threemaintain suggested herbicide rates per fold to acre. herbici Thinver approxi control applica 1.
