Updates on Pesticide Regulations
All Crops All Locations
Posted on: October 19, 2015 by Stuart Reitz
EPA has released information on new WPS standards and proposed changes to certification standards for pesticide applicators.
*******************************************************************************************************
The EPA recently announced new rules aimed at strengthening the Worker Protection Standard designed to protect farmworkers from toxic pesticides. The revisions have not gone in effect yet! The majority of the rule revisions will be effective approximately 14 months after the rule publishes in the Federal Register. This means the changes will probably be in effect in early 2017. This is to allow farmers and states time to adjust to the new requirements.
A table comparing the existing rules with the new versions can be viewed in the accompanying pdf or at: extension.oregonstate.edu/malheur/worker-protection-standard-revisions
*******************************************************************************************************
EPA is also proposing revisions to Certification standards for Private and Commercial Pesticide Applicators. A summary of the proposed changes can be viewed in the accompanying pdf or at: http://extension.oregonstate.edu/malheur/proposed-changes-pesticide-applicator-certification-rules.
EPA requests input on these proposed changes. You can submit comments to EPA until November 23, 2015. To comment, please see docket number EPA-HQ-OPP-2011-0183 at regulations.gov.

Cereals Alert - Aphids are flying, and stripe rust may be lurking - the down side of a beautiful fall
All Crops All Locations
Barley Yellow Dwarf and Stripe rust
Posted on: October 9, 2015 by Juliet Marshall
Yes, I know most of the acres of winter wheat and winter barley are already planted. If the grain is up and wasn’t treated with an insecticidal seed treatment, it will be vulnerable to aphid infestation and Barley Yellow Dwarf Virus infection. The disease Barley Yellow Dwarf (BYD) can cause significant yield loss depending upon the weather.
If planted grain WAS treated with an insecticidal seed treatment, you may still be at risk depending on date of planting. Early planted grain may run out of protection, as seed treatment protection is limited. Please see the attached file for more information!
Be aware! Aphids ARE being found in the newly planted winter wheat! While that may be good news for us in our BYDV insecticide trial and for screening for resistance in new winter wheat varieties, it will not be good news for cereal producers.
And for more information, see the CIS 1210 available online: http://www.cals.uidaho.edu/edcomm/pdf/CIS/CIS1210.pdf
Stripe rust infection in fall planted winter wheat was confirmed in Montana by Dr. Mary Burrows (visit http://www.mtagalert.org/ ). That doesn’t mean we have fall infection as well, but it definitely indicates that we have increased risk! The beautiful fall weather allows green bridge material (volunteer grain) to become well established, providing a reservoir for disease (stripe rust especially) and insects (aphids and mites) that transmit BYDV and WSMV.

Potato Psyllid
Posted on: October 2, 2015 by Amy Carroll
Tubers sampled from a potato field in Minidoka County and a field in Twin Falls County tested positive for liberibacter (Lso), the bacterium that causes zebra chip (ZC). So far this season we are aware of four fields in Idaho with confirmed ZC. Earlier this season we reported finding Lso-positive tubers from Ada and Power counties.
As the season winds down, we encourage growers and crop consultants to be on the lookout for symptomatic tubers.

Potato Psyllid
Posted on: September 25, 2015 by Amy Carroll
Nearly all of our fields have been vine killed and are no longer being monitored. However, we are maintaining sticky cards around the outside of some of our “Intense” sites in order to characterize any off-season psyllid activity. Only two psyllids were found this week from these traps (both from a field in Gooding County).
Trapping ended on all of our “Light” fields as of last week; however, some cards that arrived late last week were read this week. The relevant link below shows this update.
No new psyllids have tested positive for Lso (liberibacter, the bacterium that causes zebra chip). Some psyllids from last week remain to be tested.
Potato psyllid captures from our bittersweet nightshade sites remain relatively low as well, with 10 psyllids collected from among the four Treasure Valley sites and 11 psyllids collected from among the four Magic Valley sites.
Consult our website for more information, including management recommendations and online spreadsheets that show details of the psyllid captures in potato fields over the season. Updates to these spreadsheets may occur throughout the week as liberibacter testing results come in.

potato psyllids
Posted on: September 19, 2015 by Erik Wenninger
Abundance of potato psyllids in potato fields in Idaho appears to be lower than last week, with 85 total psyllids captured on sticky cards and vacuum samples thus far (versus 139 captured last week). Several of our “Intense” cards from the Treasure Valley will be processed Monday next week and updated results will be posted at the links below. Captures came from the following counties: Canyon, Ada, Owyhee, Gooding, Twin Falls, Jerome, Minidoka, and Cassia.
Many of our sites, including nearly all of the “Light” sites have been vine killed or harvested and will no longer be sampled.
None of the psyllids that were captured last week was positive for liberibacter (Lso), the bacterium that causes zebra chip, though a few psyllids remain to be tested.
Potato psyllid captures from our bittersweet nightshade sites in the Treasure Valley that arrived late last week were markedly lower than the previous fortnightly sample, with only 4 psyllids found (this is in contrast with the 54 psyllids that we reported on capturing in the Magic Valley sites).
As always, we encourage growers and crop consultants to scout for symptomatic plants and to consider the risk level this year when making insecticide decisions through the remainder of the season.

Aphids and Beet Leafminer
Posted on: September 17, 2015 by Ariel Agenbroad
The weather is cooling off, but some insect pests are enjoying a resurgence in the garden.
Watch your fall brassica crops like cabbage, kale and broccoli for new generations of aphids, they are flourishing in the cooler temperatures. Spray any insects off with a stream of water or use an insecticidal soap.
Also watch for leafminer damage in your late season spinach, beets and Swiss Chard. Removing and disposing of any affected leaves is the best strategy at this point in the season. For next year, use a protective row cover to keep the flies off their favorite crops!

Posted on: September 11, 2015 by Amy Carroll
Abundance of potato psyllids captured on sticky cards in potato fields in Idaho was similar to last week, with 139 total psyllids captured. Captures came from the following counties: Canyon, Ada, Owyhee, Gooding, Twin Falls, Jerome, and Minidoka counties . In addition, we found 8 nymphs and 4 eggs across three fields in Gooding, Jerome, and Twin Falls counties.
Several more fields have undergone vine kill and are no longer being sampled.
None of the psyllids that were captured last week was positive for liberibacter (Lso), the bacterium that causes zebra chip. A few psyllids remain to be tested. None of the psyllids that remained to be tested at this time last week was positive for Lso.
Some sticky cards have yet to come in this week. As these samples are processed, we will post updated results at the links below.
Psyllid abundance from our fortnightly bittersweet nightshade sampling appears to be up this week. We found a total of 54 potato psyllids (48 from vacuum samples and 6 from sticky cards) across three of our four Magic Valley sites (the Twin Falls Park site is temporarily inaccessible due to construction). Samples from our Treasure Valley sites just arrived and are still in process.
We continue to encourage growers and crop consultants to scout for symptomatic plants and to consider the typical late-season surge in psyllid abundance when making insecticide decisions through the remainder of the season.

Abundance of potato psyllids captured on sticky cards in potato fields in Idaho was about 50% higher this week than last with 149 total psyllids. Captures came from Canyon, Ada, Owyhee, Elmore, Gooding, Twin Falls, Jerome, Blaine, and Cassia counties. Several fields have undergone vine kill and are no longer being sampled.
Four of the psyllids that were captured last week were positive for liberibacter (Lso), the bacterium that causes zebra chip. These were from Canyon (one psyllid from each of three different fields) and Owyhee counties.
With the summer winding down and much of our crew having dispersed back to school, we are running a bit behind on leaf and vacuum samples (last week’s results are posted below; only one psyllid was found in a vacuum sample). We expect to complete these next week at which time we will post at the links below.
From our bittersweet nightshade sampling last week, we found a total of 22 psyllids among Treasure Valley and Magic Valley sites; this is about 50% lower than our previous fortnightly sample.
We continue to encourage growers and crop consultants to scout for symptomatic plants and to consider the late-season increase in psyllid abundance when making insecticide decisions through the remainder of the season.

Creating Habitat for Pollinators and Beneficial Insects Farm Tour
Farmers interested in increasing pollinator and beneficial insect habitat on their farms are invited to attend a farm tour at Purple Sage Farms in Middleton, Idaho on Wednesday, September 16.
Purple Sage Farms, the Northwest Center for Alternatives to Pesticides (NCAP) and The Xerces Society will host the tour from 2 to 5 pm.
Tim and Mike Sommer of Purple Sage Farms grow certified organic herbs, greens and specialty produce in their greenhouses, low tunnels and in-field production. The Sommers also raise grass-fed sheep and cattle, an important part of the nutrient cycling on the farm and from which they make their own compost.
Jessa Kay Cruz, senior pollinator conservation specialist with the Xerces Society, will discuss her work with farmers establishing habitat for pollinators and beneficial insects. She will give an overview of pollinators and beneficial insects, their habitat requirements, steps to assessing existing habitat, and organic methods of site preparation for establishing habitat.
The Sommers are working with NCAP and The Xerces Society to incorporate additional pollinator and beneficial insect habitat on their 50-acre farm. They are currently conducting different methods of organic site prep, prior to planting starts into hedgerows this fall. The farm also supports pollinators and beneficial insects through annual plantings, cover crops and allowing production areas to reach flowering.
The tour will conclude with refreshments and a presentation on a new crop insurance program, Whole-Farm Revenue Protection, which provides an opportunity for specialty crop and organic producers to secure risk coverage.
The cost is $20 and pre-registration is required. Register online at www.pesticide.org or contact Jen Miller (jmiller@pesticide.org or 208-850-6504) by September 10.
This tour is made possible by support from USDA Natural Resources Conservation Service Conservation Innovation Grant and USDA Risk Management Agency Education partnership funding. This is an equal opportunity event.
The Northwest Center for Alternatives to Pesticides (NCAP) works to protect community and environmental health and inspire the use of ecologically sound solutions to reduce the use of pesticides.

Posted on: August 29, 2015 by Erik Wenninger
Total abundance of potato psyllids captured in potato fields in Idaho was similar to last week, with the highest overall numerical count we’ve recorded this year from sticky traps: 102 total potato psyllids. Captures came from Canyon, Ada, Owyhee, Elmore, Gooding, Twin Falls, Jerome, Cassia, and Power counties.
Two of the psyllids that were captured last week were positive for liberibacter (Lso), the bacterium that causes zebra chip. These were from Gooding and Minidoka counties.
With the summer winding down and much of our crew having dispersed back to school, we are running a bit behind on leaf and vacuum samples and on samples from bittersweet nightshade. We hope to have these completed early next week. Leaf and vacuum sample results will be posted at the links below when completed.
We regret to report that there was a problem with some of the liberibacter samples that we sent to campus to be tested a few weeks ago. These were rerun, and it turns out that incidence was lower than previously reported. Corrected liberibacter incidence can be found on the spreadsheets linked below. In spite of this, risk of ZC appears to be higher this year than during the previous two, given the higher abundance of potato psyllids and the presence of liberibacter in psyllids earlier in the season. Therefore, we continue to encourage growers and crop consultants to scout for symptomatic plants and to consider this risk level when making insecticide decisions through the remainder of the season.

Liberibacter-positive tuber found in Idaho potato field
Potato All Locations
zebra chip
Posted on: August 25, 2015 by Erik Wenninger
One of the tubers that was sampled recently from a field in Ada County tested positive for liberibacter (Lso), the bacterium that causes zebra chip (ZC). The sample was taken from one of our “Intense” sites that has seen a relatively large number of liberibacter-positive psyllids. Both foliar and tuber symptoms have been difficult to find in this and other fields that we’ve inspected, so at least in these fields, overall ZC incidence appears to be low.
Nevertheless, risk of ZC appears to be higher this year than during the last two, especially in the Treasure Valley, so we continue to encourage growers and crop consultants to scout for symptomatic plants and to consider this risk level when making insecticide decisions through the remainder of the season.

Total abundance of potato psyllids captured in potato fields in Idaho increased about 50% relative to last week; most of this increased abundance occurred in the Treasure Valley. We captured 97 psyllids on sticky cards in fields across the Treasure and Magic Valleys, including fields in Canyon, Ada, Owyhee, Elmore, Gooding, Twin Falls, Jerome, and Minidoka counties. We also found a psyllid on a card submitted to our lab from Power County. In addition, we found a total of seven potato psyllid nymphs from leaf samples collected two different fields in Gooding and Jerome counties.
Two of the psyllids collected last week from potato fields tested positive for liberibacter (Lso), the bacterium that causes zebra chip. Also, two psyllids that we collected in vacuum samples from bittersweet nightshade in Shoshone Falls Park in Twin Falls tested positive for liberibacter.
Risk of zebra chip appears to be higher this year than the last two, especially in the Treasure Valley, so we continue to encourage growers and crop consultants to scout for symptomatic plants and to consider this risk level when making insecticide decisions through the remainder of the season.

Black Mold on Onion
Onion Treasure Valley
Black Mold of Onion - Aspergillus niger
Posted on: August 21, 2015 by Stuart Reitz
Black mold has been found in some early harvested onions in the Treasure Valley.
Black mold is caused by the fungus Aspergillus niger. This disease can develop in the field or during storage. The predominant symptom is a black discoloration of tissue. Infected bulbs may show blackening at the neck, streaks or spots of black fungal spores on or beneath the outer scales, and black discoloration in bruised areas.
Bulbs usually get infected by the fungus through wounds, especially through the neck as onions mature and tops fall over or are cut. The fungus is common in the soil and on dead plant material and spores can readily spread through the air.
Therefore, keeping bulbs in good condition will help prevent disease development.
It is critical to promptly and adequately dry bulbs after harvest so there is not too much moisture in the necks to promote disease development. Remember, warmth and moisture favor disease development.
It is also important to avoid wounding and bruising when bulbs are harvested, transported, or stored.
Storing bulbs at low temperatures (35°F to 55°F) and low humidity helps to control black mold if the bulbs have been cured properly.
