EPA has extended the delay for respirator fit testing until September 30, 2021.
All Crops All Locations
Posted on: May 21, 2021 by Jerry Neufeld
Due to
the COVID19 pandemic, and concerns about obtaining respirators and annual fit
testing as required by the WPS, EPA has provided guidance for delaying the
annual fit testing. This delay will be effective until September 30,
2021. EPA expects employers and handlers to make every effort to
comply with all pesticide label and Agricultural WPS requirements.
If all
options to find new respirators and get handlers fit tested, are exhausted,
EPA's guidance provides the following additional options:
- Reuse and extend use of disposable N95 filter facepiece
respirators, - Use of "expired" respirators,
- Use of respirators certified in certain other countries
or jurisdictions meeting protective conditions outlined, - Delay the annual respirator "fit
test".
Potential
risk to handlers can be minimized if the handlers and the employers comply with
all other requirements of the WPS and pesticide labels if:
- Handlers have received an annual fit test during
calendar year 2019 or 2020 and continue to use that specific respirator
make and model, - Handlers have not had a physiological change that
affects the seal (e.g. 20lb. weight loss or gain, facial surgery, scarring
since last fit test), - Handler employer can demonstrate that the handler
received respirator training in the previous 12 months.
THIS
AMENDMENT TO THE WPS EXPIRES SEPTEMBER 30, 2021.

Sugarbeet Root Maggot - 2021
Sugarbeets All Locations
sugarbeet root maggot
Posted on: May 19, 2021 by Jerry Neufeld
The growing degree day calculator (gdd) (hosted by the
Integrated Plant Protection Center at Oregon State University; http://uspest.org/cgi-bin/ddmodel.us)
for the sugarbeet root maggot fly shows that—depending on your location in the
Treasure Valley— the peak flight of root maggot flies began a few days
ago. The gdd model does an excellent job
of predicting peak flight, but monitoring with orange sticky stake traps is the
best way to get local information on fly numbers for a given field to determine
if you have the threshold numbers of flies.
Root maggot flies will lay eggs near sugarbeet plants. After
the larvae hatch they will begin feeding on the young sugarbeets. Look for
these pests to appear in the western end of the Treasure Valley first. The optimal timing for applying granular
insecticides against root maggots is within 10 days of peak flight. Granular insecticides must be watered in well
to get good uptake by the sugarbeets. The
Amalgamated Sugar Company field consultants are reporting that root maggot fly pressure
appears to be light at the moment in the Treasure Valley, but there are some
elevated levels of root maggot flies in eastern Idaho . If you suspect you are having issues with these
pests contact your TASCO field consultant.

Control Handbook and the TASCO “Fly Monitoring Readings”.

Educational Video-Monitor Flying Insects to Improve Management
All Crops All Locations
Posted on: March 3, 2021 by Jason Thomas
Do you know what types of insects are entering your field and garden at different times of the year? Would you like more information to help you decide when to implement pest control actions? The University of Idaho Extension just recently released this 5 minute video to demonstrate a way to monitor for flying insects entering your crop or garden. Click the link below to watch.
https://youtu.be/9C-V09gDfY8
Monitoring insects entering your field/garden can help you know when to take specific control actions. For example, in seed potato production it is a critical practice to help us monitor when aphids potentially harboring viruses enter a field. The traps do most of the work for you. You just have to check it every so often and maintain it over the growing season. Utilizing traps can be a helpful way to implement integrated pest management into your operation.
For other insect trapping/monitoring ideas the following demonstrational videos may be helpful:

Posted on: February 21, 2021 by Stuart Reitz
Please help us gather valuable information about chlorpyrifos (Lorsban and related insecticide products).
Restrictions on the use of chlorpyrifos and the complete revocation of its registration are under way. Our team has initiated a cross-commodity collaborative research project to identify viable options as alternatives to chlorpyrifos. Research will be conducted at several locations in Oregon to determine the efficacy of currently registered chemistries and newer products in onion, corn, cherries, grass seed, and clover seed. This survey will provide critical information on the use of chlorpyrifos across all crops and will help us identify issues to improve our research project.

Research and Outreach Programming for Pulse Crops
All Crops All Locations
Posted on: February 9, 2021 by Jerry Neufeld
Montana State University needs your help to improve our research and outreach programing for pulse crops. We’ve created a survey to help us collect information that will directly impact what we research, how we develop our future programming, and also increase our ability to apply for pulse crop research funding.
The survey should take about 10 minutes to complete. You can use your phone, computer, or tablet.
Your responses are completely anonymous – we have no way of connecting people to answers. Also, the data we collect are always aggregated (all answers summarized together), so that individual responses are never seen by anyone but the researchers.
Here’s a link to the survey: https://bit.ly/Pulses2021; you can copy it into your browser.
If you have any questions about the survey or our research, please don’t hesitate to contact Mary Burrows at mburrows@montana.edu or my research associate at monica.brelsford@montana.edu or by phone at (406) 994-5155.
Thank you for helping out research and Extension!

Armyworm damage in eastern Idaho wheat fields
Small Grains Eastern Idaho
armyworm
Posted on: October 6, 2020 by Jerry Neufeld
The following information is provided by Dr. Arash Rashed, Associate Professor, Department of Entomology, Plant Pathology and Nematology at the University of Idaho.
There have been reports of fall armyworm damage in some wheat fields between American Falls and Firth in eastern Idaho. Please inspect your fields as managing this pest is more effective during the early stages of development. Fall Armyworms are active during dark, so field inspections need to be done with a flashlight after sunset. They have a wide host range but prefer grasses; at this time of the year, wheat, barley, alfalfa, volunteers, and pasture are examples of crops that can host fall armyworms. They feed on foliar tissue and can consume young seedlings to the ground. During the day they hide in plant litter and/or just below the soil surface. There are no set thresholds and management recommendations depend on the stages of plant and larval development and the extent of the damage. More than 2-3 larger larvae (> 1/2in) per square foot may require control. Scout as many spots as possible within a field. Damage by fall armyworm is usually patchy and spot insecticide treatment is a possibility, where needed. Larvae cannot survive freezing temperatures and are also susceptible to diseases caused by entomopathogens at high densities.
For other closely related species and damage, you can visit pages 493-499 of the publication in the first link below:
You can also learn more about this pest from the PNW Insect Management Handbook in the second link below:

Final psyllid trap capture report for the 2020 season
Potato All Locations
potato psyllid
Posted on: September 10, 2020 by Erik Wenninger
This week we had traps deployed in 45 of the 65 fields (69%) monitored this year; 20 fields had been vine killed and were not monitored. We found a total of 105 psyllids across 16 (35%) of the 45 fields.
Psyllids were collected on sticky traps in potato in the following counties: Canyon (5 fields), Owyhee (1 field), Elmore (4 fields), Twin Falls (5 fields), and Power (1 field).
From last week’s samples, no psyllids tested positive for Lso (liberibacter), the bacterium associated with zebra chip disease (ZC).
We are not including “heat maps” this week given that they tend to show skewed patterns with smaller sample sizes.
This week concludes our 2020 psyllid monitoring program, following recommendations from our ZC Advisory Committee of shortening the duration. However, we will report on the last set of Lso results next week.
Total psyllid captures are still down from two weeks ago and based on previous years’ observations we would expect their numbers to continue to reduce; however, psyllids likely will continue dispersing among the remaining fields as vine kill continues. Overall captures of psyllids this season were higher than the last two seasons, though still nowhere near as high as the “epic” years of 2016 and 2012. Thus far, we have also seen our lowest incidence of Lso-positive psyllids yet (0.4%). Together, we expect that the modest psyllid abundance and very low Lso incidence this year should result in relatively low incidence of ZC in harvested tubers. But remember that, at least in our experiments with Russet Burbank, some risk of ZC remains if infection occurs within 1-2 weeks before vine kill.

Potato Psyllid
Posted on: September 3, 2020 by Lucy Standley
This week we had traps deployed in 48 of the 65 fields (73%) monitored this year; 17 fields have been vine killed and will no longer be monitored. We found a total of 92 psyllids across 18 (37%) of the 48 fields.
Psyllids were collected on sticky traps in potato in the following counties: Canyon (7 fields), Owyhee (1 field), Elmore (4 fields), Twin Falls (4 fields), and Power (2 fields).
From last week’s samples, no psyllids tested positive for Lso (liberibacter), the bacterium associated with zebra chip disease (ZC). However, due to shipping delays from last week, a few Lso results will be delayed until next week.
We are not including “heat maps” this week given that they tend to show skewed patterns with smaller sample sizes.
Total psyllid captures were down considerably this week, which was related to fewer fields being monitored but also fewer captures in most of the remaining fields. It appears that we saw peak seasonal captures last week. However, remember that, at least in our experiments with Russet Burbank, some risk of ZC remains if infection occurs within 1-2 weeks before vine kill.
