final report of the 2024 potato psyllid / Lso monitoring season.

potato psyllid

Posted on: September 12, 2024 by Tasha Stanzak

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 years (with the exception of 2022 in which 22% were positive).

It was another
interesting year with moderately high Lso incidence, but relatively low overall
psyllid captures. Captures were only slightly higher than last year. Thus, the
risk of ZC likely was mitigated somewhat by low psyllid captures despite
relatively high Lso.

Please remember
that our research with Russet Burbank shows that ZC can develop during storage
if infection occurs as late as two weeks before vine kill. Please maintain your
IPM programs, especially in areas with higher captures of Lso-positive
psyllids.

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 captures increase a bit; no new Lso positives

potato psyllid

Posted on: September 5, 2024 by Tasha Stanzak

• 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 to their highest level overall this season; however, captures are still relatively low and similar to the season-long totals from last year. Thankfully, no new Lso-positive psyllids were collected last week. Although psyllid captures have been relatively low this season, Lso incidence was slightly higher than in most recent years, which may slightly elevate risk of ZC. Please maintain you IPM programs, especially in areas with higher captures of Lso-positive psyllids.

This is our last week of retrieving traps from the field and reporting on captures. Next week we will report on Lso testing results from the psyllids collected this week and wrap up the season.

Psyllid captures still low; one new Lso positive

potato psyllid

Posted on: August 29, 2024 by Erik Wenninger

• This week we received traps from 53 of the 58 fields that we are monitoring; 5 sites are finished for the season.

• We captured a total of 19 psyllids across 5 fields.

• Captures were from the following counties: Payette, Canyon, and Twin Falls.

• One of the psyllids collected last week tested positive for Lso.

Psyllid captures continue to be relatively low overall—slightly lower than last week and similar to the low captures we saw over the last two years at this time. We did find another Lso-positive psyllid last week so—despite the low captures—we are seeing some positives, which may slightly elevate the risk of ZC. A psyllid from a set of sticky traps that arrived late to us could not be tested, so we will have those results by next week. As we get into vine kill, remember that our research with Russet Burbank shows that ZC can develop during storage if infection occurs as late as two weeks before vine kill.

Posted on: August 23, 2024 by Tasha Stanzak

·        
This week we received traps from 57 of the 58
fields that we are monitoring

·        
We captured a total of 30 psyllids across 14 fields.
Four of these psyllids were from traps that were in the field for two weeks.

·        
Captures were from the following counties:
Payette, Canyon, Owyhee, Jerome, and Twin Falls.

·        
None of the psyllids collected last week tested
positive for Lso.

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 shown that ZC can develop during storage if
infection occurs as late as two weeks before vine kill.

Posted on: August 15, 2024 by Erik Wenninger

• This week we received traps from 38 of the 58 fields that we are monitoring; two of our crop consultant collaborators were not able to get to their fields this week but we expect to get those traps next week. 

• We captured a total of 16 psyllids across 5 fields.

• Captures were from the following counties: Payette, Canyon, Owyhee, and Twin Falls.

• One of the psyllids collected last week tested positive for Lso.

Psyllid captures were relatively low again this week and similar to the captures observed at this time during the last two years. Of course, we did not receive traps from several fields, but last week most of those fields showed zero psyllid captures (and a few had one capture), so we may expect to see only a slight increase in the total captures when we get those trap captures added to the tallies. One Lso-positive psyllid from last week was from Payette County. We continue to see a smattering of Lso-positives psyllids over this season; however, the relatively low psyllid captures overall should mitigate risk of ZC.

• This week we received traps from 58 of the 58 fields that we are monitoring. 
• We captured a total of 21 psyllids across 11 fields.
• Captures were from the following counties: Payette, Canyon, Owyhee, and Twin Falls.
• Four of the psyllids collected last week tested positive for Lso.

Psyllid captures declined this week relative to last week. Captures overall continue to be moderately low and similar to the last two years. One Lso-positive psyllid was from Payette County, one from Elmore County, and two from Twin Falls County. Incidence of Lso usually diminishes over the season, though it is not unheard of to see a few positive psyllids in July to August. Thankfully overall captures have been relatively low this year, which should mitigate risk of ZC even with slightly higher Lso incidence in psyllids.

Psyllid captures continue to be moderate. Captures this week were only slightly higher than what we found at this time over the last two years. Captures in the Treasure Valley and Upper Snake were similar to last week; captures in the Magic Valley ticked up only slightly relative to last week. We have captured a total of only 3 Lso-positive psyllids so far, which is lower than the Lso incidence we found at this time over the last few years. Typically we find the highest incidence of Lso in psyllids early during the season, so this low incidence so far is a good sign that overall Lso incidence for this season may be low.

Yellow rust (stripe rust), Bacterial leaf streak / black chaff, FHB, frost damage in wheat, barley

Yellow (stripe) rust, Bacterial leaf streak, FHB

Posted on: July 17, 2024 by Juliet Marshall

The early season for Idaho was cool and unusually rainy. The weather was good for growth of winter and spring cereals. Stripe rust started developing in winter wheat (LCS Jet in production south of American Falls.) The season was mostly quiet until June 18^th – 19^th when there were significant frosts and freezing conditions throughout eastern Idaho. 

As a result, bacterial infections took off, significantly damaging durum (Tiburon) and spring wheat. 

Stripe rust started to show up at very low levels at the end of June, around heading of spring wheat. Initially the hard red spring wheat WB9707 was the first to show infection. Within 2 weeks, WB7696 (hard white spring), WB7313 (hard white spring), and now Holmes (hard red spring wheat) are also showing significant symptoms in production fields. Many other varieties are showing infections and will be rated soon in the Extension Variety Trials. Spring wheat is currently in early grain fill.

There is some BLS in spring barley as well, although it (black chaff) seems much more severe in spring wheat.

Some FHB has been collected in production fields of winter barley. Low levels of FHB are starting to show in spring wheat production fields around Idaho Falls. Night time temperatures and humidity are higher than usual due to cloud cover. Skies are hazy due to smoke from western fires.  I am keeping an eye out for the development of additional FHB.

• 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 week tested positive for Lso.

• None of the other psyllids collected last week tested positive for Lso. We are still waiting on results from 4 psyllids that were delivered to us late last week.

Psyllid captures this week were higher than at this time in the last two years; however, captures have not been as high as 2020-2021. It is noteworthy that we are now seeing similar numbers of psyllids per field across the state. We typically see higher captures in the Treasure Valley before captures increase across the rest of the state, so these observations are unusual. Thankfully we did not see an uptick in Lso-positive psyllid captures this week.

2024 Potato psyllid monitoring program underway in Idaho

potato psyllid

Posted on: July 4, 2024 by Erik Wenninger

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 at least 10 weeks. We have 58 fields across the state this year, using 4 sticky traps per field at all sites. 

• This week we received traps from all 58 fields that we are monitoring. 

• We captured a total of 53 psyllids across 19 fields.

• Captures were from the following counties: Payette, Canyon (3 fields), Owyhee, Twin Falls (10 fields), Jerome, Cassia, Minidoka, and Bingham. 

• Sites in Twin Falls County had a total of 43 psyllids. 

• We also captured 1 psyllid from the Kimberly Research & Extension Center last week that tested positive for Lso.

• For psyllids captured this week, we expect to have results on Lso incidence next week. 

Psyllid captures this week were higher than at this time in the last two years. It is noteworthy that most of the captures came from the Magic Valley, and most of those from one field (though captures in Twin Falls County were widespread). We typically see higher captures in the Treasure Valley before the Magic Valley, so these observations are unusual. It is not uncommon to see a few Lso-positive psyllids early in the season and fewer as the season progresses. However, if we continue to see relatively high captures in addition to more Lso-positives, this will represent higher ZC risk. 

Given the potentially higher ZC risk, we strongly urge growers to have their IPM programs in place. More information on management can be found here:
