Psyllid captures ticked up relative to last week but were still relatively low compared to recent years. Thankfully, we found zero Lso-positive psyllids last week. This season’s low overall psyllid captures and moderate Lso incidence (in previous weeks) suggests low to moderate risk for ZC. We still suggest maintaining your IPM programs. Our research has…
Psyllid captures were relatively low again this week and similar to the captures observed at this time during the last two years. Of course, we did not receive traps from several fields, but last week most of those fields showed zero psyllid captures (and a few had one capture), so we may expect to see…
Psyllid captures declined this week relative to last week. Captures overall continue to be moderately low and similar to the last two years. One Lso-positive psyllid was from Payette County, one from Elmore County, and two from Twin Falls County. Incidence of Lso usually diminishes over the season, though it is not unheard of to…
• This week we received traps from 58 of the 58 fields that we are monitoring.• We captured a total of 38 psyllids across 16 fields.• Captures were from the following counties: Payette, Canyon, Owyhee, Elmore, Twin Falls, and Minidoka.• Three of the psyllids collected last week tested positive for Lso. Psyllid captures ticked up…
• This week we received traps from 58 of the 58 fields that we are monitoring.• We captured a total of 30 psyllids across 14 fields.• Captures were from the following counties: Payette, Canyon, Gooding, Twin Falls, Minidoka, and Bingham.• None of the psyllids collected last week tested positive for Lso. Psyllid captures continue to…
Psyllid captures have been ticking down slightly over the last two weeks. Captures this week were similar to what we found at this time over the last two years. So, after seeing moderately high captures at the start of the monitoring season, we are now seeing relatively low captures. We have captured a total of…
• This week we received traps from all 58 fields that we are monitoring.• We captured a total of 34 psyllids across 15 fields.• Captures were from the following counties: Canyon (4 fields), Owyhee, Twin Falls (6 fields), Gooding, Jerome, Bannock, and Bingham.• One more psyllid collected from the Kimberly Research & Extension Center last…
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.
