I have a few semi dwarf citrus trees that I am growing in trees boxes. I am finding Japanese beetle grubs/ larvae in the soil. How much can I apply in a 2.5 gallon watering can to kill these grubs via a drenching method? My tree boxes are 36" boxes. These grubs eats the roots I am told.
Sevin Concentrate is not labeled for white grubs or for use in containerized plants. Bonide Systemic Granules can be use for grubs in ornamental plants (not if you eat the citrus).
