What is the application rate for 4' English Boxwood to control white flies?
I live in Alabama
Merit Granules are not labeled for white flies. We would recommend using Adonis 2F Insecticide. You will mix 0.1 to 0.2 fl. oz. per inch of the trunk diameter. You will mix this in at least 10 gallons of water. Remember when using a product like this, the amount of water is not as important as using the correct amount of product.
