• This week we received traps from 52 of the 58 fields that we are monitoring.
• We captured a total of 40 psyllids across 11 fields.
• Captures were from the following counties: Payette, Canyon, Owyhee, Elmore, and Twin Falls.
• None of the psyllids collected last week tested positive for Lso.
Psyllid captures increased this week to their highest level overall this season; however, captures are still relatively low and similar to the season-long totals from last year. Thankfully, no new Lso-positive psyllids were collected last week. Although psyllid captures have been relatively low this season, Lso incidence was slightly higher than in most recent years, which may slightly elevate risk of ZC. Please maintain you IPM programs, especially in areas with higher captures of Lso-positive psyllids.
This is our last week of retrieving traps from the field and reporting on captures. Next week we will report on Lso testing results from the psyllids collected this week and wrap up the season.

Psyllid captures still low; one new Lso positive

• This week we received traps from 53 of the 58 fields that we are monitoring; 5 sites are finished for the season.
• We captured a total of 19 psyllids across 5 fields.
• Captures were from the following counties: Payette, Canyon, and Twin Falls.
• One of the psyllids collected last week tested positive for Lso.
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 a set of sticky traps that arrived late to us could not be tested, so we will have those results by next week. As we get into vine kill, remember that our research with Russet Burbank shows that ZC can develop during storage if infection occurs as late as two weeks before vine kill.

Homeowners, growers, dealers, and professional applicators storing unusable or unwanted pesticides will have a safe and free opportunity to dispose of them at an ISDA pesticide disposal site.
ISDA pesticide disposal sites will take most pesticides including herbicides, insecticides, fungicides, rodenticides or anything ending with “cide.” No high-pressure canisters, fertilizer, micronutrients, paint, solvents, motor oil, or rinsates other than seed treat rinsates will be accepted. Loads exceeding 1,000 pounds must be pre-registered.

Psyllid captures still low; no new Lso-positives

·
This week we received traps from 57 of the 58
fields that we are monitoring
·
We captured a total of 30 psyllids across 14 fields.
Four of these psyllids were from traps that were in the field for two weeks.
·
Captures were from the following counties:
Payette, Canyon, Owyhee, Jerome, and Twin Falls.
·
None of the psyllids collected last week tested
positive for Lso.
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 shown that ZC can develop during storage if
infection occurs as late as two weeks before vine kill.

IPM programs in place. More information on management can be found here:

Psyllid captures remain relatively low; one more Lso positive

• This week we received traps from 38 of the 58 fields that we are monitoring; two of our crop consultant collaborators were not able to get to their fields this week but we expect to get those traps next week.
• We captured a total of 16 psyllids across 5 fields.
• Captures were from the following counties: Payette, Canyon, Owyhee, and Twin Falls.
• One of the psyllids collected last week tested positive for Lso.
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 only a slight increase in the total captures when we get those trap captures added to the tallies. One Lso-positive psyllid from last week was from Payette County. We continue to see a smattering of Lso-positives psyllids over this season; however, the relatively low psyllid captures overall should mitigate risk of ZC.
