I want to use this product to prevent borers on my larage shade trees. How many ounces should I use per gallon...
Mixing Hi-Yield 38-Plus Insect Control - 38% Permethrin at 1.6 fl uid ozs. (3 1/4 Tablespoons) per 1 gallon of spray solution to make a 0.5% spray emulsion.
To prevent infestation of Ornamental Trees and Woody Shrubs, spray the bark to the point of saturation, but do not let runoff occur. Repeat treatment every 21 days during early Spring until Mid-Summer
