I have a hydrangea tree that I cannot rid of cottony scale. I've tried contact insecticides as well as soaps but I'd like to treat the soil also - will Merit be appropriate for that?
Merit 75 WP - 2 oz. jar will treat scale insects. You can apply this product as a soil injection or soil drench around the base, for the root system to soak up and translocate up. Please refer to the Merit 75 Wp product page, as we have listed the applications to trees and shurbs. Also, be sure to refer to the product label for application as well.
