No new positive psyllids

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 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). This is good news considering the prevalence of positive psyllids the last two weeks, but we still urge growers to have their IPM programs in place.
