Insecticides for Control of Leafhoppers in Dry Beans

Updated March 11, 2003 by Gary Hein and John Thomas

Economic Threshold:
Potato leafhopper is potentially a serious problem in dry beans. Normally immigration of the leafhopper into Nebraska reduces its potential for damage, but in some years significant populations can develop. The threshold for potato leafhoppers is one leafhopper (adult or immature) per trifoliate leaf.
