Psyllid captures remain low; no new positives

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 we continue to see quite low numbers this season.

All of the psyllids captured last week were negative for Lso, the bacterium associated with zebra chip disease (ZC). We still urge growers to have their IPM programs in place given the prevalence of Lso earlier in the season.
