Objective:
Assess feeding deterrence effects of Cyazypyr on potato psylllid to prevent or minimize transmission of zebra chip potato disease.

Approach:
Cyazypyr, a DuPont product has been shown to deter feeding and oviposition in Hemipteran insect vectors (e.g., whiteflies and thrips) and preventing disease transmission to vegetable crops. Potato plants in the greenhouse and small field cages will be treated with Cyazypyr and exposed to liberibacter-infective potato psyllids. After insect exposure, the plants will be monitored for zebra chip symptoms to estimate disease incidence.
