Potato Psyllid
Posted on: 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 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 All Locations
Posted on: 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.

powdery mildew
Posted on: 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.

Potato Pest Alert for the week ending 6-19-2015
Potato All Locations
Posted on: June 19, 2015 by Phill Wharton
The weather has finally turned and the sun has come out. In most growing areas this week temperatures have been in the 80’s or higher. With the dry warm weather across the snake river valley the risk of a late blight outbreak is low. However, micro-climates may exist in fields where conditions are conducive for late blight. Areas such as low spots where soil moisture is highest and parts of the field shaded by windbreaks are examples of areas where scouting should be intensified. For information on what fungicides to use for managing late blight see the article recently published by Dr. Jeff Miller of Miller Research and Dr. Phill Wharton from UI (http://bit.ly/1Q4tmty).
In the Treasure Valley area and western Idaho most potato crops are now past row closure and the first reports of early blight are starting to come in. For information on early blight control see (http://bit.ly/1CinqBN). Whatever product you use to control early blight it is always recommended that you tank mix it with a protectant fungicide such as Chlorothalonil or Dithane, unless the product already contains it (e.g. Gavel or Zing!). This reduces the chances of fungicide resistance development.
In the Magic Valley area most crops are just at row closure and it is around this time that growers should be making their first application for early blight/ white mold control. Dr. Jeff Miller reports that in fields that didn't receive an insecticide treatment at planting, Colorado beetles are beginning to appear.
In east and north eastern part of the state (Pocatello up through Tetonia) crops are between the 6-8” stage and touching in the rows. There have not been any reports of disease problems this week. If you are growing a variety which is susceptible to black dot, or have had problems with black dot in the past, the 6-8” plant stage is the optimal timing to apply a black dot control product such as a strobilurin (Quadris Top, Gem, Reason, Headline etc).

June 19, 2015 – Another Lso-positive psyllid found in a potato field
No psyllids collected last week were positive; however, one of the psyllids collected this week from a Twin Falls County potato field tested positive for Lso, the bacterium that causes zebra chip. A few psyllids collected this week remain to be tested.
Psyllid abundance this week was similar to last week. Potato psyllids were found this week in the following counties: Payette, Canyon, Gooding, Jerome (two fields), and Twin Falls (two fields).
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.
