September 23, 2016 – Potato psyllid monitoring winds down
As many fields have been vine killed and/or harvested, the psyllid sampling season is winding down. Sampling continued in only a handful of fields this week and will all but cease next week.
Potato psyllids were collected this week on sticky traps in potato in the following counties: Gooding (1 field), Twin Falls (1 field), Jerome (2 fields), Minidoka (1 field), and Cassia (4 fields).
This week, we collected 44 psyllids from sticky cards (37 from Light sites and 7 from Intense sites). We found psyllids in 8 of the 10 fields (80%) that were sampled this week. Total captures declined in part because sampling has ceased in most fields and likely also because of cooler weather.
We ran Lso testing on a subset of psyllids collected last week (up to ten psyllids per site). So far, none of the psyllids tested last week was positive for Lso. As always, the online spreadsheets (see below) may be updated at any time during the week as more data are gathered.
As fields are harvested, we urge everyone to familiarize themselves with ZC tuber symptoms. See link below for description and photos of ZC symptoms, and please take suspicious samples to the Kimberly R&E Center or to your local UI Extension Center.
More information and resources on potato psyllids and ZC, including management, scouting recommendations, and ZC symptomology can be found at the links below.
