Determine susceptibility of different potato plant growth stages to BLTVA phytoplasma under field conditions using leafhopper exclusion and exposure studies. Determine susceptibility of different potato plant growth stages to BLTVA phytoplasma under field conditions by timing applications of selected insecticides targeted against the beet leafhopper. Assess the impact of the timing of BLTVA infection on the potato yield, tuber processing quality, and phytoplasma transmission rate in daughter tubers. Develop treatment (action) thresholds for the beet leafhopper to reduce incidence of purple top disease in Columbia Basin potatoes.
