What would be a good choice for an insecticide to spray to control western corn rootworm beetles to keep them from silk feeding? Would probably be applied with a ground rig. Corn ranges from probably 10 days till silking to currently silking right now.
Whats a good threshold as far as number of beetles per plant or how much silk they can eat before they harm pollination?
