All Crops All Locations
Posted on: February 8, 2016 by Nora Olsen
There will be an important Virus Detection Training Workshop on Monday, June 20th, 2016 at the WSU Research Farm, 1471 West Cox Road in Othello, WA. The workshop will cover field identification of PVY (strains O, N-Wi and NTN), including visual identification of foliar symptoms on 40 major cultivars. We will also have samples of different tuber symptoms from PVY, PMTV and TRV. In addition, we will be discussing and demonstrating new diagnostic assays for viruses and soil-borne vectors of some of the viruses. Additional workshops planned for the week include the WSU Commercial Seed Lot Evaluation (Tuesday June 21st) in Othello, the OSU Potato Field Day at the OSU Research and Extension Center, 2121 S. 1st Street, Hermiston, OR (Wednesday June 22nd) and the WSU Potato Field Day in Othello (Thursday June 23rd). Come and make a week of it!
University and USDA experts at the Virus Detection Training Workshop will include Stewart Gray (USDA-ARS/Cornell), Mark Pavek (WSU), Jonathan Whitworth (USDA-ARS/ID), Amy Charkowski (UWI), Alex Karasev (UID) and Nina Zidack (MtSU). The workshop is part of a USDA NIFA Specialty Crops Initiative award titled “Biological and economic impacts of emerging potato tuber necrotic viruses and the development of comprehensive and sustainable management practices”.
The recent standardization of seed certification programs across the U.S. includes the requirement for documentation of inspector training, but this training will also be beneficial to growers, people who rogue, and industry in general, so please sign up early. To register for the event please visit http://bit.ly/wsu-potatovirusworkshop. For more information about the workshop please email pbg-potatovirus@cornell.edu.

Barley Yellow Dwarf Virus is being found in early-planted fall wheat in areas southern and eastern Idaho. Symptoms include various degrees of yellowing, reddening, and purpling of the leaves.
Alate aphids were found in the fields prior to cold temperatures. See the picture of the aphids provided by Dr. David Hole in Logan Utah.

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.

If you had confirmed cases of Shothole Disease, Peach Leaf Curl or other fungal diseases in your Peaches, Apricots and Nectarines, fall spraying can be an effective part of your protection and prevention strategy.
At about 50% leaf fall, spray an approved Copper Based Fungicide, Bordeaux Mixture or Lime Sulfur at the rate listed on the product.

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.
Photos of typical ZC symptoms exhibited by foliage and tubers may be found here:

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.
