• This week we received traps from 48 fields that we are monitoring.• We captured a total of 38 psyllids across 13 fields.• Captures were from the following counties: Payette, Canyon, Jerome, Gooding, and Twin Falls.• Among the 13 psyllids captured last week, none tested positive for Lso. Psyllid captures this week ticked up from…
• This week we received traps from 47 fields that we are monitoring.• We captured a total of 9 psyllids spread across 8 fields.• Captures were from the following counties: Payette, Canyon, Jerome, Gooding, and Twin Falls.• The 3 psyllids captured last week all tested negative for Lso.• For psyllids captured this week, we expect…
The University of Idaho and our crop consultant collaborators across the state are once again monitoring potato psyllids, zebra chip disease (ZC), and liberibacter (Lso), the bacterium associated with ZC. The monitoring program covers commercial potato fields throughout southern Idaho and is funded largely by the Idaho Potato Commission and generous in-kind contributions by our…
This is the final report of the 2024 potato psyllid / Lso monitoring season. One psyllid from last week’s samples tested positive for Lso, the bacterium associated with zebra chip disease (ZC). About 4% of all psyllids tested positive for Lso this year compared to about 6% last year and around 1% in most recent…
• 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…
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…
• 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…
• This week we received traps from 58 of the 58 fields that we are monitoring.• We captured a total of 30 psyllids across 14 fields.• Captures were from the following counties: Payette, Canyon, Gooding, Twin Falls, Minidoka, and Bingham.• None of the psyllids collected last week tested positive for Lso. Psyllid captures continue to…
Psyllid captures have been ticking down slightly over the last two weeks. Captures this week were similar to what we found at this time over the last two years. So, after seeing moderately high captures at the start of the monitoring season, we are now seeing relatively low captures. We have captured a total of…
• This week we received traps from all 58 fields that we are monitoring.• We captured a total of 34 psyllids across 15 fields.• Captures were from the following counties: Canyon (4 fields), Owyhee, Twin Falls (6 fields), Gooding, Jerome, Bannock, and Bingham.• One more psyllid collected from the Kimberly Research & Extension Center last…
