I have used Safari as a foliage spray, but just learned it does not work on adult whiteflies. Will this product kill adult whiteflies? Is yes, how much per gallon of water?
Yes, Hi-Yield 38-Plus Insect Control 38% Permethrin can be applied as a foliar spray to control whiteflies. The rate per the product label on ornamentals is: 0.04 to 0.08 fl. ozs. (1/8 to 1/4 tsp.) (1 to 2 ml.) per gallon
