Potato Insecticide Evaluation
The Colorado potato beetle (CPB) and the potato leafhopper (PLH) are two important insect pests that need to be controlled to achieve profitable potato production. The CPB, in particular, is troublesome because it has developed resistance to insecticides in the carbamate, organophosphate, and pyrethroid chemical groups. Currently, insecticides in the neonicotinoid group provide effective control of CPB, but there are concerns that with continued use of neonicotinoids this resilient pest will also develop resistance against this group of insecticides. The goal of this project was to evaluate potato insecticides with different modes of action for use in a CPB resistance management program.
