Objective:
Develop integrated pest management of the potato psyllid and Liberibacter in a multicrop system.

Approach:
Conduct insect transmission studies under laboratory conditions to determine Liberibacter acquisition and inoculation access time required for the potato psyllid to effectively transmit the bacterium and induce diseases. Determine the impact of Liberibacter on different plant growth stages under controlled field cage conditions. Determine density of potato psyllid required for this insect pest to effectively cause diseases in potato, tomato, and pepper.
