August 1, 2019 Psyllid captures declined a bit this week

Potato Psyllid
Posted on: August 1, 2019 by Lucy Standley
This week we had traps deployed in 81 of the 82 fields (98.7%) monitored this year, and we found a total of 67 psyllids across 27 (32.9%) of the 82 monitored fields. However, we are still waiting to receive traps from 19 sites in eastern Idaho. One of the 82 total fields that we 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, we continue to urge growers to maintain their IPM programs, especially given that we 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.
