The Pacific Northwest Pest Alert is reporting that psyllid captures are slightly down.
This week they had traps deployed in 81 of the 82 fields (98.7%) monitored this year, and they found a total of 67 psyllids across 27 (32.9%) of the 82 monitored fields. However, they are still waiting to receive traps from 19 sites in eastern Idaho. One of the 82 total fields that they were sampling has been vine-killed.
Psyllids were collected on sticky traps in potato in the following counties: Payette (3 fields), Canyon (12 fields), Owyhee (1 field), Elmore (3 fields), Twin Falls (6 fields), Cassia (1 field), and Minidoka (1 field).
All psyllids collected last week tested negative for Lso (liberibacter), the bacterium that causes zebra chip.
Psyllid captures dropped a bit relative to last week; however, they continue to urge growers to maintain their IPM programs, especially given that they have historically seen an increase in captures during August.
“Heat maps” of this week’s results will soon be included on the UI and WSU websites (see links below), pending resolution of technical difficulties we are currently having with them.
