Prior to this project, there was no available experimental information on insecticide toxicity against the leafhopper X-disease vectors Colladonus Reductus and C. geminatus  In 2020 we performed lab bioassays to screen various insecticide products against the most abundant of these two species in Washington cherries, C. reductus. Five insecticide materials achieved 100% mortality of C. reductus: 3 conventional and 2 organic. We will continue these screenings in 2021, with added focus on residue degradation and strategic spray timings.
