On-line resources to help minimize potato bruise at harvest
Potato All Locations
Posted on: August 10, 2020 by Nora Olsen
Potato harvest is upon us in Idaho and new on-line resources are available at the University of Idaho to help in bruise and quality management. Written and video resources can be found at www.uidaho.edu/cals/potatoes/bruise-management.
A new bulletin on ‘Monitoring tools for a potato bruise prevention program’ is now posted. This bulletin highlights tools or methods to quickly identify where in harvest and handling operation potatoes may experience physical impacts that cause blackspot and shatter bruises. The bulletin outlines a relatively simple and quick way to detect shatter bruises with the use of an iodine solution. The coloration of the shatter bruises makes it easy to determine the number and severity of the bruises. Although blackspots bruises take time to develop, recent research on Russet Burbank, Ranger Russet and Russet Norkotah indicates the ability to see a majority of the bruises within 3-5 hours after harvest. Peeling potatoes to identify early blackspot bruise symptoms is a useful monitoring tool that can help pinpoint equipment that needs to be adjusted. Another option is to run an instrumented sphere though your operation to measure the acceleration of an impact. The shape and size of the instrumented sphere mimics a potato, making it very useful tool to help identify handling equipment that may be at higher risk for bruising. Monitoring shatter and blackspot bruise levels during harvest and handling operations with the tools outlined in this bulletin provides opportunities to modify equipment and conditions; and also to identify lots or fields that have a greater degree of bruise. Training videos are also available on the website. These 3-minutes videos highlight how to run and operate equipment associated with harvest and handling of potatoes in order to prevent bruising and maximize crop quality. Available videos include:
- Windrower operation (English and Spanish)
- Harvester operation (English and Spanish)
- Moving potatoes from truck to piler (English)
- Best practices for piling potatoes (English and Spanish)
- Unloading potatoes out of storage (English)

Potato Psyllid
Posted on: August 6, 2020 by Lucy Standley
This week we had traps deployed in 64 of the 65 fields (98%) monitored this year; one field has been vine killed and will no longer be monitored. We found a total of 132 psyllids across 31 (48%) of the 64 fields, though we are still waiting for traps from one site in Canyon county.
Psyllids were collected on sticky traps in potato in the following counties: Payette (1 field), Canyon (9 fields), Owyhee (2 field), Gem (2 fields), Elmore (4 fields), Jerome (2 fields), Twin Falls (10 fields), and Oneida (1 field).
From last week’s samples, no psyllids tested positive for Lso (liberibacter), the bacterium associated with zebra chip disease (ZC). We are waiting on results for 2 psyllids (1 each from Gem and Minidoka counties), which we should have next week.
“Heat maps” of this week’s results are included on the UI and WSU websites (see links below). “Heat maps” describe predicted psyllid densities across the landscape, based on our trap counts and on predictive models developed over six years of psyllid monitoring in Idaho. The heat maps graphically reflect the relatively high abundance of psyllids collected in some fields in the Treasure Valley and around Twin Falls.
Psyllid captures were slightly higher this week, though similar to total captures during early August last year. We continue to urge growers to have their IPM programs in place.

Potato Psyllid
Posted on: July 30, 2020 by Lucy Standley
This week we had traps deployed in 65 of the 65 fields (100%) monitored this year; we found a total of 114 psyllids across 28 (43%) of the 65 fields.
Psyllids were collected on sticky traps in potato in the following counties: Payette (1 field), Canyon (10 fields), Owyhee (1 field), Gem (2 fields), Elmore (2 fields), Gooding (1 field), Jerome (2 fields), Twin Falls (7 fields), Minidoka (1 fields), and Power (1 field).
From last week’s samples, one psyllid (collected in Twin Falls County) tested positive for Lso (liberibacter), the bacterium associated with zebra chip disease (ZC). This is the second observation of an Lso-positive psyllid in our monitoring program in as many weeks. Overall incidence of Lso still remains relatively low (about 1% through last week).
“Heat maps” of this week’s results are included on the UI and WSU websites (see links below). “Heat maps” describe predicted psyllid densities across the landscape, based on our trap counts and on predictive models developed over six years of psyllid monitoring in Idaho. The heat maps graphically reflect the relatively high abundance of psyllids collected in the Western Treasure Valley.
Psyllid captures were higher this week, though similar to total captures during late July to early August last year. Given this increase and the additional observation of an Lso-positive psyllid, we continue to urge growers to have their IPM programs in place.

Potato Psyllid
Posted on: July 23, 2020 by Lucy Standley
This week we had traps deployed in 59 of the 65 fields (91%) monitored this year (though we have not yet received traps from 6 of these fields); we found a total of 83 psyllids across 28 (53%) of the 53 fields with data.
Psyllids were collected on sticky traps in potato in the following counties: Canyon (12 fields), Owyhee (2 fields), Gem (2 fields), Elmore (3 fields), Jerome (1 field), Twin Falls (7 fields), Minidoka (2 fields), and Oneida (1 field).
From last week’s samples, two psyllids tested positive for Lso (liberibacter), the bacterium associated with zebra chip disease (ZC). These hot psyllids were collected from two different fields: one in Twin Falls and one in Jerome County. This is the first observation of Lso-positive psyllids in our monitoring program this year. This is about one week and two weeks later than the first observation of Lso-positive psyllids during 2019 and 2018, respectively.
“Heat maps” of this week’s results are included on the UI and WSU websites (see links below). “Heat maps” describe predicted psyllid densities across the landscape, based on our trap counts and on predictive models developed over six years of psyllid monitoring in Idaho. These maps, developed in collaboration with WSU, should be used as a guideline, but not a definitive count of the number of insects in any given field at any given point in time. “Low,” “Moderate,” “High,” and “Very High” designations are arbitrary categories that illustrate relative abundance and should not be used as “thresholds.” More details on the “heat maps” can be found in Potato Progress Volume XVII, Number 2, 15 February 2017.
Psyllid captures were a bit higher this week, though similar to total captures during late July to early August last year. Given this increase and the first observation this year of Lso-positive psyllids in Idaho, we urge growers to have their IPM programs in place.

Powdery Mildew, Cercospora Leaf Spot and Spider Mites near Twin Falls
Sugarbeets Magic Valley
Powdery Mildew, Cercospora Leaf Spot and Spider Mites
Posted on: July 22, 2020 by Jerry Neufeld
Powdery mildew and spider mites have been found by The Amalgamated Sugar Company LLC Crop Consultants in sugarbeet fields in the Twin Falls, ID area. There are several fungicides available for use to treat powdery mildew. Depending on the disease pressure and chemistry used, applications with different chemistries should be repeated every 14-21 days. Please be advised that strobilurins could show reduced efficacy due to fungicide resistance. Always tankmix with at least 5 lbs of sulfur for resistance management purposes.
TASCO is also reporting they have confirmed Cercospora leaf spot in a sugarbeet field near Twin Falls. We have reached critical temperatures but relative humidity is still low, however overhead irrigation can artificially increase relative humidity and therefore increase infection potential. Fields in close proximity to last year’s infected fields, or back to back sugarbeet fields are especially at risk. Please contact your local AMSCO agriculturist for fungicide recommendations based on last year’s fungicide resistance survey.
Contact your Crop Consultant from The Amalgamated Sugar Company LLC if you have any questions.

Corn Earworm - 2020
Corn Treasure Valley
corn earworm
Posted on: July 20, 2020 by Jerry Neufeld
I am once again collaborating with Charter Seed Co. and Crookham Co. on a project to trap corn earworm moths. Traps will be set out in corn fields at various locations near Kuna, Melba, Middleton, Wilder, Homedale, and Caldwell. I will check the traps every few days and post the moth counts to this website.
The online Phenology and Degree Day Model (GDD) from Oregon State University is being used to estimate when the summer generation of corn earworm moths will emerge. This is the generation of moths that lay eggs in corn that is silking at the time when they emerge. The link to the GDD calculator for Corn Earworm is below.
The GDD model uses January 1 as a biofix, 55 and 92 as the temperature parameters. Summer moths will emerge after 1300 GDD have accumulated. These moths will then begin laying eggs in fresh corn silk. This model also estimates the eggs will hatch and larvae will begin feeding on corn ears 73 GDD later. According to this model, we will reach 1300 GDD in the Caldwell area about July 29, and will reach 1300 GDD in the Parma area about July 30. Egg laying in most, if not all, Treasure Valley locations will take place in this approximate time frame. Larval feeding will begin 3 to 4 days later.
Traps will go out in a couple of days. The first moth counts will be posted a few days after the traps are set out.
The links below will take you to the websites where you can use the growing degree day model and also view various treatment methods based on the type of corn that you are growing.

Potato Psyllid
Posted on: July 16, 2020 by Lucy Standley
This week we had traps deployed in 56 of the 65 fields (86%) monitored this year and we found a total of 42 psyllids across 22 (39%) of the 56 fields.
Psyllids were collected on sticky traps in potato in the following counties: Payette (1 field), Canyon (4 fields), Gem (2 fields), Elmore (1 field), Jerome (2 fields), Twin Falls (9 fields), Cassia (1 field), Power (1 field), and Oneida (1 field).
The remaining 9 fields (across Bingham and Power counties) had traps deployed in them this week, and we will report data from them next week.
Lso testing of last week’s psyllids has been delayed. We plan to report Lso results next week.
There was also an issue with the generation of “heat maps” that we expect to have resolved by next week.
Psyllid captures were similar to last week and similar to this time last year, though we urge growers to watch psyllid numbers closely during the coming weeks.

2020 Potato psyllid monitoring program in Idaho

Potato Psyllid
Posted on: July 2, 2020 by Lucy Standley
The University of Idaho and our crop consultant collaborators across the state are continuing the monitoring program 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 collaborators.
Following guidance from our ZC Advisory Committee, we are running a shortened monitoring season beginning at the end of June and continuing for 10 to 12 weeks, using 4 sticky traps per field at all sites. Complications related to COVID-19 have limited the number of sites being monitored by some of our cooperators, but we expect to still have a total of about 65 fields across the state.
The first set of traps in commercial fields was deployed last week, with quite a few more having been deployed this week. We began monitoring at the Kimberly R&E Center (KREC) during mid-June.
During the week of June 22, we captured a total of 4 potato psyllids among our three monitored fields at KREC. During the week of June 29, we captured 11 psyllids across the same fields as well as 7 psyllids across three commercial fields in Canyon county. Psyllid abundance appears to be fairly low as is typical of June, but we will obtain trap data from many more sites next week.

Iris yellow spot virus in onion
All Crops All Locations
Posted on: July 1, 2020 by Stuart Reitz
Iris yellow spot virus had been found this past week in a few plants in commercial onion fields in Malheur County, Canyon County, and Washington County. So far, no widespread outbreaks have occurred.
Maintaining good thrips management will help limit the spread and severity of the disease. Infective adult thrips spread the virus from plant to plant as well as within a plant. Infective immatures also can spread the virus within a plant.
In addition to thrips management, minimize stress on onion plants by making sure fields are maintained at an adequate but not excessive fertility level, and that the soil moisture is kept at about the 20 centibar level. This will help reduce the severity of virus symptoms.

Additional resources for potato quality improvement are now available on-line
Potato All Locations
Posted on: June 29, 2020 by Nora Olsen and Mike Thornton
As part of the Idaho Potato Commission-funded quality project we have been working with one of the largest retailers of potatoes to monitor the incidence of defects seen at the consumer level in the 2017, 2018 and 2019 potato crops. The good news is that we have seen an improvement in the quality of potatoes delivered over the three years of the project. We believe that this improvement in quality is due in large part to the emphasis on reducing bruise damage being exhibited at both the grower and shipper levels.
One of the best ways to reduce bruise damage is to focus on training the people that operate every piece of potato handling equipment on their role in the effort to improve quality. To that end, we have developed several training resources on our website under the “Bruise Management” tab. In 2019 we focused on videos that show windrower and harvester operators the key factors in operating that equipment in a way that minimizes bruise. But we realize that bruising can take place any time potatoes are handled, so in 2020 we focused on the equipment that moves potatoes from the truck into storage, the piling operation, and the process of removing the potatoes from storage. The result is three new videos entitled Moving Potatoes from Truck to Piler, Best Practices for Piling Potatoes, and Unloading Potatoes Out of Storage. Each video is only 3 to 4 minutes long, but cover the basic operating principles and show several viewpoints so that equipment operators can see what the machinery should look like when operating properly.
Special thanks go to Jason Thomas (Minidoka County Extension Educator) for the narration, and Bill Schaefer for shooting the video and editing it all into the final product.
The initial videos are available in English. However, we anticipate that a Spanish version of the videos will be posted shortly. All these videos are available at the following website:

Oregon COVID-19 Costs for Food Security & Farmworker Safety Program
All Crops Northern Idaho
Posted on: June 10, 2020 by Stuart Reitz
Oregon’s Food Security and Farmworker Safety Program provides assistance to Oregon’s agricultural producers in order to help secure Oregon’s food supply chain and protect essential agricultural workers from COVID-19 exposure and illness.
The COVID-19 emergency caused Oregon’s Occupational Safety and Health Administration (OR-OSHA) to issue temporary rules requiring increased field sanitation measures and more stringent labor housing and transportation regulations.
Agricultural producers are responsible for complying with COVID-19 emergency OR-OSHA requirements for Housing, Transportation, and Field Sanitation.
