The University of Idaho and our crop consultant collaborators across the state are once again monitoring for potato psyllids, zebra chip disease (ZC), and liberibacter (Lso), the bacterium associated with ZC. The monitoring program covers commercial potato fields throughout southern Idaho and is funded in part by the Idaho Potato Commission and generous in-kind contributions…
The primary purpose of our aphid monitoring efforts in southeast Idaho is to inform seed potato growers when aphid flights are occurring. Seed potato growers are interested in this information because many aphid species can vector Potato virus Y (PVY), an economically impactful virus for the seed potato grower since seed potatoes becomes ineligible for…
Although spores were detected, no diseased plants were reported for Idaho in 2022 or 2023. There were no spore detections for 2020 or 2021.
This is the final report of the 2023 potato psyllid / Lso monitoring season. All of the psyllids tested last week were negative for Lso, the bacterium associated with zebra chip disease (ZC). About 6% of all psyllids tested positive for Lso this year compared to around 1% in most recent years (and 22% last…
