First potato psyllid nymphs found in a potato field in Idaho

Potato     
July 2, 2015 by Erik Wenninger

Overall abundance of potato psyllids in potato fields was similar this week (28 adults total) compared to last (26 adults total), though numbers were higher this week relative to last in the Treasure Valley. Psyllids were collected this week from the following counties: Canyon, Ada, Owyhee, Gooding, Jerome, Twin Falls, Minidoka, Cassia, and Blaine. We collected one psyllid at the Kimberly Research & Extension Center.

We also collected our first potato psyllid nymphs (three total) this year from a field in Cassia County.

In addition, we collected many potato psyllids from bittersweet nightshade sites in the Magic Valley, including 37 from vacuum samples at Shoshone Falls Park.

None of the potato psyllids that we collected last week tested positive for Lso, the bacterium that causes zebra chip (though three psyllids that arrived at our lab late last week have yet to be tested).

We continue to urge growers and crop consultants to have an IPM program in place and to supplement our monitoring program with their own local monitoring.

Consult our website for more information, including 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 Lso testing results come in.

Potato psyllid numbers increasing in Magic Valley potato fie

Potato     
June 26, 2015 by Amy Carroll

June 26, 2015 – Potato psyllid numbers increasing in Magic Valley potato fields

Abundance of potato psyllids appears to be increasing in the Magic Valley. We collected eight psyllids from one site in Jerome County. This week, we also collected potato psyllids from three different Canyon County fields (one psyllid per site), six different fields in Twin Falls County (one psyllid per site), one psyllid from another site in Jerome County, and seven psyllids from five sites (two on one field) in Cassia County. This represents our first psyllid captures this season in Cassia County. In addition, we collected our first psyllid since April at the Kimberly Research & Extension Center.

Aside from the one positive psyllid we reported on last week, none of the other potato psyllids that we collected last week tested positive for Lso, the bacterium that causes zebra chip.

We continue to urge growers and crop consultants to have an IPM program in place and to supplement our monitoring program with their own local monitoring.

Consult our website for more information, including 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 Lso testing results come in.

Plant Disease Diagnostic Submission Form

     Treasure Valley - Idaho
Ada county, Idaho
June 26, 2015 by Olga Walsh

Plant Disease Diagnostic Service.

As you know, Dr. Krishna Mohan retired from UI this past spring. In order to continue plant disease diagnostic services, we have had to change the submission procedures. Samples will now be processed through the Idaho State Dept. of Agriculture Plant Pathology Lab rather than the Parma Research & Extension Center. Liz Vavricka, Plant Pathologist at the ISDA lab, will serve as the contact and has requested the following protocols for sample submission:

All plant samples should be submitted by extension personnel. Liz would like an email
(Liz.Vavricka(u;agr i.idaho.gov) or DDDI (Distance Diagnostics through Digital
Imaging) (http://www.dddi.org/idahoO notification of the incoming sample. Both emails and DDDI entries should include pictures if possible. Emails should include the information on the attached form. If a diagnosis can be made based on the photo, then no physical sample will be necessary. If a physical san1ple is necessary, it should be sent to ISDA at the address below.

Physical samples sent to ISDA should be dry and placed in a brown paper bag. If roots are included, they should be wrapped with saran wrap and rubber banded. The attached form should be filled out and inserted in the bag or included. Samples should be kept cool (refrigerated if possible) until shipped. Most can be shipped in the regular mail. Please mark the outside of the shipping container (box or envelope) with a note that says "SAMPLE ENCLOSED" and ship to:

Potato Pest Alert for the week ending 6-26-2015

Potato     
June 26, 2015 by Phill Wharton

Dr. Mike Thornton reports that there are not a lot of disease issues coming through the door right now. In the Treasure Valley area, we are seeing a little bit of early blight on lower leaves, especially on plants that are stressed due to virus infection or other issues. Speaking of stress, the hot days and warm nights forecast for the next week or so can be very hard on potato plants. To reduce the incidence of physiological disorders like sugar ends, it is important to adjust irrigation schedules to account for the increase in water demand by the crop. Growers cannot afford to get behind on irrigation under these conditions, as even a single stress event at this critical time of tuber development can cause high levels of malformed tubers and reduce processing quality.

In the Magic Valley area Dr. Nora Olsen reports that the only significant disease issues they are seeing are related to PVY infection of potatoes. The high temperatures in the area also appear to be putting some crops under stress as many which were almost at row closure last week still have not closed rows yet this week.

In east and north eastern part of the state Pocatello up through Tetonia), there have been no disease problems reported apart from some PVY issues. Many crops are at flowering now and should be at row closure in the next week or so. As with other parts of the state hot days and warm nights are forecast for the next couple of days so it is imperative to adjust irrigation schedules to account for the increase in water demand by the crop. Increased stress on the plants can make them more susceptible to disease and insect problems.

     Treasure Valley - All
Malheur county, Oregon
June 25, 2015 by Jerry Neufeld

Powdery mildew has been found by Amalgamated Sugar Company Crop Consultant Howard Binford in a sugarbeet field in the Adrian, Oregon area. There are several fungicides available for use to treat powdery mildew, including sulfur dusts. Depending on the disease pressure, applications with different chemistries should be repeated every 7 to 14 days. Contact your crop consultant from the Amalgamated Sugar Company if you have questions about treatment options.
