Objective:
Investigate the role of the potato psyllid and liberibacter in the zebra chip (ZC) potato disease.

Approach:
Conduct laboratory and field studies to 1) increase understanding of potato psyllid feeding and liberibacter transmission biology, 2) continue studies to evaluate the impact of potato planting time on ZC, 3) continue to investigate the impact of liberibacter/ZC infection on different potato plant growth stages, determine timing of liberibacter/ZC translocation into potato tubers, and evaluate postharvest ZC development in tubers, 4) investigate the impact of psyllid feeding and density, as well as environmental factors on liberibacter, ZC incidence, potato yield, and tuber processing quality, and 5) potato variety screening under controlled field cage conditions.
