3 Lso positive psyllids; captures tick up only slightly

• 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 only slightly this week relative to last week. Captures overall continue to be moderate and similar to last year. One Lso-positive psyllid was from Payette County and two from Twin Falls County. Incidence of Lso usually diminishes over the season, though it is not unheard of to see a few positive psyllids in July to August. Thankfully overall captures have been moderate this year, which should mitigate risk of ZC even with slightly higher Lso incidence in psyllids.

Nevertheless, we urge growers to have their IPM programs in place. More information on management can be found here:
