psyllid captures continue to be moderate; no new Lso positives

potato psyllid
Posted on: July 25, 2024 by Tasha Stanzak
• 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 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.
Nevertheless, we urge growers across the state to have their IPM programs in place. More information on management can be found here:

• This week we received traps from 57 of the 58 fields that we are monitoring.
• We captured a total of 14 psyllids across 11 fields.
• Captures were from the following counties: Canyon (2 fields), Owyhee, Jerome (2 fields), Twin Falls (4 fields), Cassia, and Bingham.
• One more psyllid collected last week in Twin Falls County tested positive for Lso.
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 3 Lso-positive psyllids so far, which is lower than the Lso incidence we found at this time over the last few years.

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 18th – 19th 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.

psyllid captures similar across the state
Potato All Locations
potato psyllid
Posted on: July 12, 2024 by Tasha Stanzak
• 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.
We urge growers across the state to have their IPM programs in place. More information on management can be found here: https://www.uidaho.edu/extension/ipm/ag-pests/arthropods/psyllids

Cercospora Leaf Spot in Sugarbeet
Sugarbeets All Locations
Cercospor Leaf Spot
Posted on: July 12, 2024 by Oliver Never
Sugarbeets - Treasure Valley, Western Magic Valley
University of Idaho and Amalgamated Sugar Company personnel have identified Cercospora leaf spot in fields near Parma ID, Wilder ID, and Glenns Ferry ID. Incidence is still low, however, most fields have closed rows, Cercospora spores have been detected in spore traps deployed in the Treasure Valley, and environmental conditions have been conducive for infection for a couple of weeks now.
If fungicide applications have not yet occurred, we strongly encourage everyone to start spraying against Cercospora leaf spot.
Several fungicides are available but be aware of multiple fungicide-resistant strains of Cercospora. Depending on the disease pressure and chemistry used, applications with different chemistries should be repeated every 14 days. Using a protectant such as copper products, EBDCs, or hydrogen peroxide with every spray is strongly recommended.[https://www.srcoop.com/articles/2024_Fungicide_Recommendations.pdf ]
Contact your crop consultant from the Amalgamated Sugar Company to discuss suitable fungicides for your area, to report a loss of fungicide efficacy, or if you have any questions.

2024 Potato psyllid monitoring program underway in Idaho
Potato All Locations
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:

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

Psyllid captures dropped this week

potato psyllid
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.
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

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.

Posted on: July 25, 2024 by Tasha Stanzak
• 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 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.
Nevertheless, we urge growers across the state to have their IPM programs in place. More information on management can be found here:

• This week we received traps from 57 of the 58 fields that we are monitoring.
• We captured a total of 14 psyllids across 11 fields.
• Captures were from the following counties: Canyon (2 fields), Owyhee, Jerome (2 fields), Twin Falls (4 fields), Cassia, and Bingham.
• One more psyllid collected last week in Twin Falls County tested positive for Lso.
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 3 Lso-positive psyllids so far, which is lower than the Lso incidence we found at this time over the last few years.

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 18th – 19th 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.

Posted on: July 12, 2024 by Tasha Stanzak
• 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.
We urge growers across the state to have their IPM programs in place. More information on management can be found here: https://www.uidaho.edu/extension/ipm/ag-pests/arthropods/psyllids

Cercospora Leaf Spot in Sugarbeet
Sugarbeets All Locations
Cercospor Leaf Spot
Posted on: July 12, 2024 by Oliver Never
Sugarbeets - Treasure Valley, Western Magic Valley
University of Idaho and Amalgamated Sugar Company personnel have identified Cercospora leaf spot in fields near Parma ID, Wilder ID, and Glenns Ferry ID. Incidence is still low, however, most fields have closed rows, Cercospora spores have been detected in spore traps deployed in the Treasure Valley, and environmental conditions have been conducive for infection for a couple of weeks now.
If fungicide applications have not yet occurred, we strongly encourage everyone to start spraying against Cercospora leaf spot.
Several fungicides are available but be aware of multiple fungicide-resistant strains of Cercospora. Depending on the disease pressure and chemistry used, applications with different chemistries should be repeated every 14 days. Using a protectant such as copper products, EBDCs, or hydrogen peroxide with every spray is strongly recommended.[https://www.srcoop.com/articles/2024_Fungicide_Recommendations.pdf ]
Contact your crop consultant from the Amalgamated Sugar Company to discuss suitable fungicides for your area, to report a loss of fungicide efficacy, or if you have any questions.

2024 Potato psyllid monitoring program underway in Idaho
Potato All Locations
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:

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

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.

Psyllid trapping ends for the season.

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

Psyllid captures dropped this week

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.

Psyllid captures per field similar to last week

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

Psyllid captures tick up slightly, but still relatively low

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.
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
