Psyllid captures this week were slightly lower than last week and similar to the moderately low captures we saw during this period in the last three seasons. Although we captured a few Lso-positive psyllids last week, the modest overall captures should mitigate ZC risk. We saw similar patterns last year (i.e., relatively low captures with…
Psyllid captures this week were similar to the relatively low captures during this period in the last 2-3 seasons. With relatively low psyllid captures and only two Lso-positive psyllids detected so far, ZC risk appears to be relatively low this year. That could change as the season progresses and temperatures rise, so stay tuned.
Psyllid captures continue to be relatively low overall—slightly lower than last week and similar to the low captures we saw over the last two years at this time. We did find another Lso-positive psyllid last week so—despite the low captures—we are seeing some positives, which may slightly elevate the risk of ZC. A psyllid from…
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…
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…
This week we received traps from 31 of the 55 fields that we are monitoring. Twenty-two fields have been vine killed or are senescing and are no longer being monitored. We captured a total of 15 psyllids across 7 fields. Five of the fields were in Canyon County, and the other two fields were in…
This week we received traps from 49 of the 55 fields that we are monitoring. We captured a total of 44 psyllids across 14 fields. Ten of the fields were in Canyon County; the remaining 4 fields were in Payette, Elmore, and Twin Falls counties. Total psyllid captures ticked up slightly, at least in the…
This week we received traps from 50 of the 55 fields that we are monitoring. We captured a total of 30 psyllids across 12 fields. Seven of the fields were in Canyon County, the remaining 5 fields were in Payette, Owyhee, Elmore, and Twin Falls counties. Total psyllid captures were similar to last week, and…
This week we received traps from 53 of the 55 fields that we are monitoring. We captured a total of 21 psyllids across 9 fields. Six of the fields were in Canyon County, the remaining 3 fields were in Payette, Owyhee, and Twin Falls counties. Total psyllid captures were slightly higher than last week, but…
