Research Project: Management of Potato Psyllid and Zebra Chip Disease

Location: Fruit and Vegetable Insect Research

Project Number: 2092-22000-020-04
Project Type: Specific Cooperative Agreement

Start Date: Sep 06, 2011
End Date: Sep 05, 2016

Objective:
To assess impact of 1) liberibacter-free and liberibacter-infected psyllids on plant emergence, viability, disease incidence, and yield; 2) zebra chip on potato seed quality of different potato varieties; and 3) zebra chip on potato seed quality depending on timing of plant disease infection.

Approach:
Tubers produced by potato plants of different cultivars exposed to liberibacter-free and liberibacter-infected psyllids will be planted in small field cages. Cages will be monitored for plant emergence, seed viability, zebra chip incidence, yield, and tuber processing quality. In addition, tubers produced by potato plants inoculated with liberibacter at different plant growth stages will be planted in similar small field cages and evaluated as above.
