final report of the 2023 potato psyllid / Lso monitoring season.

potato psyllid
Posted on: September 21, 2023 by Tasha Stanzak
This is the final report of the 2023 potato psyllid / Lso monitoring season.
All of the psyllids tested last week were negative for Lso, the bacterium associated with zebra chip disease (ZC).
About 6% of all psyllids tested positive for Lso this year compared to around 1% in most recent years (and 22% last year).
It was another interesting year with somewhat high Lso incidence, but relatively low overall psyllid captures. Captures were only slightly higher than last year, which was among our lowest years ever. Thus, the risk of ZC likely was mitigated somewhat by low psyllid captures despite relatively high Lso.
Thanks again to all of our cooperators who helped to deploy and retrieve so very many yellow sticky traps! And thanks to the growers who let us use their fields for this work!

Psyllid trapping wrap up

potato psyllid
Posted on: September 14, 2023 by Tasha Stanzak
We officially ended the monitoring season last week, but we received a bonus week of sticky traps from two fields in Canyon County this week. We captured a total of 12 psyllids across these 2 fields.
None of the six psyllids captured last week was positive for Lso, the bacterium associated with zebra chip disease (ZC). Next week we will report Lso results for the 12 psyllids submitted this week and provide an end-of-season wrap up.
About 7% of all psyllids tested positive for Lso this year compared to around 1% in most recent years (and 22% last year). It is too soon to tell what this low psyllid / somewhat high Lso season means for ZC in tubers at harvest. Our studies in Russet Burbank showed that ZC can develop during storage if infection occurs as late as two weeks before vine kill. Please consider this in your late-season IPM programs. Risk could be mitigated by processing tubers from fields at higher risk sooner rather than later.

potato psyllid
Posted on: September 7, 2023 by Tasha Stanzak
This week we received traps from 20 of the 55 fields that we are monitoring. Thirty-three fields have been vine killed or are senescing and are no longer being monitored. We captured a total of 6 psyllids across 3 fields. The three fields were in Canyon, Elmore, and Twin Falls counties.
This is our last week of actively trapping psyllids. We will post the final results next week to finish out the monitoring season.
One psyllid tested from last week’s Canyon County captures was positive for Lso, the bacterium associated with zebra chip disease (ZC); the rest of the psyllids captured last week were negative for Lso. This is the first Lso positive we have detected since early July.
With harvest season upon us, it is worth remembering that our studies in Russet Burbank showed that ZC can develop during storage if infection occurs as late as two weeks before vine kill. Please consider this in your late-season IPM programs. More information on management can be found here: https://www.uidaho.edu/cals/potatoes/news/psyllid-management

Posted on: September 1, 2023 by Erik Wenninger
This week we received traps from 31 of the 55 fields that we are monitoring. Twenty-two fields have been vine killed or are senescing and are no longer being monitored. We captured a total of 15 psyllids across 7 fields. Five of the fields were in Canyon County, and the other two fields were in Elmore and Twin Falls counties.
Total psyllid captures dropped notably from last week. The slightly cooler temperatures and precipitation likely contributed to lower captures.
All psyllids tested from last week’s captures were negative for Lso, the bacterium associated with zebra chip disease (ZC); however, the results from the psyllids that arrived to us late are still pending. Interestingly, we still have not had a positive psyllid since early July.

Posted on: August 25, 2023 by Tasha Stanzak
This week we received traps from 35 of the 55 fields that we are monitoring. One field was vine killed and we are still waiting on traps from 19 sites. Many of these fields could not be entered earlier in the week so traps were shipped to us late. We captured a total of 30 psyllids across 10 fields. Four of the fields were in Canyon County; the remaining 6 fields were in Elmore, Gooding, and Twin Falls counties.
Total psyllid captures per field were similar to last week, though several of the fields still unaccounted for are sites where we’ve seen relatively high captures this season. Updated results will be posted on the sites (below) early next week, and we’ll send out another alert if anything unexpected is observed.
All psyllids tested from last week’s captures were negative for Lso, the bacterium associated with zebra chip disease (ZC). We have not had a positive psyllid since early July.
Nevertheless, we urge growers to have their IPM programs in place. More information on management can be found here: https://www.uidaho.edu/cals/potatoes/news/psyllid-management

This week we received traps from 49 of the 55 fields that we are monitoring. We captured a total of 44 psyllids across 14 fields. Ten of the fields were in Canyon County; the remaining 4 fields were in Payette, Elmore, and Twin Falls counties.
Total psyllid captures ticked up slightly, at least in the Treasure Valley; however, captures were still relatively low compared to previous years. This is the time of year that we typically see captures increase, so this uptick is not surprising.
All psyllids tested from last week’s captures were negative for Lso, the bacterium associated with zebra chip disease (ZC); results are pending for seven psyllids that were shipped late. Although we saw relatively high prevalence of Lso in early samples, we have not had a positive psyllid since early July.

Total psyllid captures were similar to last week, and we continue to see relatively low numbers this season.
However, 12 of the 14 psyllids we captured last week were positive for Lso, the bacterium associated with zebra chip disease (ZC). In addition, one of the three psyllids from the previous week that was shipped late also tested positive. Thus, 15 of the 19 psyllids tested this season have been positive.
It is not unusual to see more Lso-positive psyllids early in the season, but this level of Lso is higher than we typically see. It is fortunate that psyllid numbers are quite low, but the high prevalence of Lso suggests that we should be vigilant. We strongly urge growers to have their IPM programs in place.

First Lso-positive psyllid of the season
Potato All Locations
potato psyllid
Posted on: July 14, 2023 by Erik Wenninger
Apologies! This alert was posted on Friday, but an alert was not sent.
This week we received traps from all 55 fields that we are monitoring. We captured a total of 14 psyllids across 10 fields. Seven of the fields were in Canyon County; the remaining 3 fields were in Owyhee, Twin Falls, and Minidoka counties.
One of the psyllids we collected last week from Canyon County was positive for Lso, the bacterium associated with zebra chip disease (ZC). The other psyllids from last week were shipped to us late, so results are expected by Monday (and will be posted to the Idaho Pest Monitoring Dashboard, below). A positive psyllid this early in the season is somewhat concerning. ZC risk is in part a function of psyllid numbers and Lso incidence, so it is fortunate the psyllid numbers have been low so far. Nevertheless, we urge growers to watch psyllid captures closely and to have their IPM programs in place.

2023 Potato psyllid monitoring program underway in Idaho
Potato All Locations
potato psyllid
Posted on: July 7, 2023 by Tasha Stanzak
The University of Idaho and our crop consultant collaborators across the state are once again monitoring for 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 in part by the Idaho Potato Commission and generous in-kind contributions by our cooperators.
Our official monitoring season began with wide deployment of traps last week and will continue for 10 to 12 weeks. We have 55 fields across the state this year, using 4 sticky traps per field at all sites.
This week we received traps from 52 of the 55 fields that we are monitoring. We captured a total of four psyllids across three fields, all in Canyon County. In addition, a limited number of fields was monitored prior to the official start of the monitoring program. We captured one psyllid in a field in Canyon County last week and zero so far over four weeks of monitoring at the Kimberly Research & Extension Center.
It is still early, but thus far we are seeing relatively low numbers of psyllids, similar to the numbers we observed in 2022.
We expect to have results on Lso incidence next week.
Please visit our new site, the Idaho Pest Monitoring Dashboard, for graphical summaries of our psyllid captures for this season and the previous three seasons: https://idahopestmonitoring.org/
We will be posting and archiving our weekly updates on this site. So in addition to the graphical summaries, you will be able to look back on all the weekly “blog” summaries and easily compare this year’s captures to previous years.

Yes, it's true - come learn about the wheat and barley varieties that available to our area producers, cropping systems, fertility management and yes, those dang pests! What can be more fun that talking about smut? (Dwarf, loose, flag and cover your smut!) Scalds? Head blight?
Representatives from private industry, commissions and University of Idaho will be there, so hope to see you at one of the events!

2023 Fruit Thinning – June 21, 2023
Cultural Alert
Fruits which are crowded on limbs should be thinned. Apples, pears, Asian pears, apricots, plums, and peaches all respond positively to thinning. Cherries and nut trees are usually not thinned. Thinning fruit will 1) increase fruit size, 2) improve the trees productivity in the year to come, and 3) reduce limb breakage as fruits begin to size. Too many fruits on a tree translates into small fruit that is often of poor quality.
General rules for thinning: 1) the earlier the better, 2) remove smaller fruits and leave the larger ones, 3) remove fruits with disease spots, hail damage, or other defects, 4) aim for even spacing.
General guidelines by fruit – see links below for additional detail.
Apples & pears: Almost always need thinning. Should be thinned to one fruit per spur with a good spacing of one fruit per 6” of branch. Asian pears spaced at one fruit per 6-8” of branch. Be careful not to break off spurs while thinning – spurs produce flowers and fruit for many years if not broken. Recommend to thin apples within 40 days of full bloom and pears within 60 days of full bloom.
Peaches & nectarines: Should be spaced at one fruit per 6-8” of branch. Fruits that are joined should be removed. Recommend to thin peaches about 70 days past full bloom.
Plums: Should be thinned to have spacing at 6” between fruit along the branch.
Apricots: If tree experiences heavy fruit set thin fruit spaced to 3” along branch.
Trees will exhibit “June Drop” which is when the tree will naturally drop fruit. Some prefer to wait until this event happens to thin, however there are great advantages to thinning early. More details can be found in the links below.
