Powdery Mildew on organic Table grape
Small Fruits Treasure Valley - Idaho
Posted on: September 19, 2008 by Tony McCammon
Field Day and Vineyard Tour: Managing Powdery Mildew at Rocky Fence Vineyard Saturday, September 20, 1‐3 pm, Emmett, Idaho
Presented by: University of Idaho Extension, Rocky Fence Vineyard, University of Idaho Pomology Program
Funded by: Western Sustainable Agriculture Research and Education (WSARE) 2008 Professional + Producer Grant
AGENDA
1:00 PM Welcome, registration, introductions
1:30 PM Begin facilitated vineyard tour of the powdery mildew project
2:30 PM Question and answer with grower, Extension faculty and researchers, refreshments
3:00 PM Adjourn
Organic table grape production may be a good match for southwest Idaho’s rapidly changing agricultural
landscape. Population has increased over 30% since 2000 and farms are downsizing. Producers want successful
alternative crops to diversify operations and generate income.
Michael Medes of Rocky Fence Vineyards, a producer of organic table grapes, will use this Professional + Producer
Grant to seek solutions to powdery mildew, the most threatening disease to marketable fruit. With Ariel
Agenbroad and Tony McCammon, and with the support of Dr. Esmaeil Fallahi and Dr. Krishna Mohan, they will test the effectiveness of preventive management practices, implement an expanded trellis system, scout and test for early detection and use climate‐based disease forecasting and organically approved fungicide treatments.
Project findings will be shared at two annual on‐farm demonstration events, conferences and in future Extension publications. This field day is the first of these events.

Table Grape Growers Can Learn About Powdery Mildew
Management at Sept. 20 Field Day in Emmett
EMMETT, Idaho—While organic table grapes have the potential to become a lucrative new alternative crop for small- to mid-range producers in southwestern Idaho, powdery mildew is threatening growers’ ability to harvest high-quality, marketable fruit. Most of the available information on managing this disease has been developed for growers in California, Washington and Oregon, but Treasure Valley producers can tour ongoing local research from 1 to 3 p.m. Saturday, Sept. 20, at a field day at Rocky Fence Vineyard in Emmett.
“Managing this disease is critical to the success of producers and to the sustainability of the industry,” says Ariel Agenbroad, University of Idaho Canyon County Extension educator. She and colleague Tony McCammon of Payette County and grower Mike Medes will lead a tour and hands-on demonstration of research funded by a two-year Western Region Sustainable Agriculture Research and Education Producer + Professional Grant.
Entitled “A Multi-Faceted Approach to Managing Powdery Mildew on Organic Table Grapes in Southwest Idaho,” the project’s partners include University of Idaho pomologist Essie Fallahi and plant pathologist Krishna Mohan, both located in Parma.
The free field day will be held at 3770 Fuller Road in Emmett. The tour will focus on:
• developing powdery mildew management protocols for southwestern Idaho
• trellising systems and pruning strategies for optimal air flow and operator access
• timing and materials for preventative treatment
• scouting and early detection of the disease organism
• using disease forecasting models
• timing treatments with organically approved materials
• exploring the use of composts and compost teas in fertility and disease control
Refreshments will be provided and RSVP is appreciated. For more information, call the University of Idaho’s Canyon County Extension Office at (208) 459-6003.

Late blight in Minidoka County
Potato All Locations
Posted on: August 20, 2008 by Jeff Miller
Late blight has been confirmed in two more fields in Minidoka County. One was a few miles north of Paul and the other near Norland. The location of these fields indicates that the pathogen has been spread over a larger area than first estimated.
It is critical to continue fungicide applications as long as vines are green. Gavel, Omega, Revus Top, and Tanos are good stand alone products for foliar late blight control. Revus Top and Tanos are also effective against early blight. Gavel has some EBDC premixed with the product. Curzate, Forum, and Previcur and can be mixed with a standard protectant such as chlorothalonil or an EBDC to provide greater protection than using chlorothalonil or an EBDC alone. Strobilurin products such as Headline, Quadris, and Reason are similar to standard protectants when used at the early blight rate and the higher end of the rate range should be used for late blight protection.
Late blight in Minidoka County
Potato All Locations
Posted on: August 15, 2008 by Jeff Miller
Late blight was found in two more potato fields in Minidoka County today, bringing the total number of confirmed fields to three. These two fields are located a couple of miles north of Paul and both are north of the first confirmed field. The disease pattern in these fields is consistent with spread from another source. It is likely that thundershowers last week spread the pathogen and it is possible that other fields in the area have been affected. It is essential that fields be scouted and any suspicious lesions be analyzed by trained personnel.
These additional findings underscore the importance of reporting late blight. An accurate knowledge of disease incidence is essential so all growers can know how often to apply fungicides. Please report any potential late blight findings so that accurate alerts can be posted.
These finds also show that late blight can get started inside the potato canopy even when overall weather conditions have not been favorable for disease development. Fields with actively growing plants in the Rupert and Paul area should be treated weekly with protectant fungicides such chlorothalonil or EBDC. Other fungicides with greater efficacy can be either tank-mixed with protectants or used in place of protectants.
If you have questions or concerns please contact Jeff Miller at 208-431-4420.

Posted on: August 7, 2008 by Jerry Neufeld
According to UI CIS 366 “Timing Corn Earworm Control” summer moths began laying eggs in fresh corn silk at approximately 1300 growing degree days (GDD), approximately August 2. Egg hatch and larvae attack begins about 73 GDD later. The peak egg laying period should be between now and 1650 GDD. If you have fresh silking corn during this period (about the next two weeks) it is important to monitor for corn earworm larvae and treat if necessary.

Late blight in southern Idaho
Potato All Locations
Posted on: August 4, 2008 by Jeff Miller
Late blight was confirmed today in the Mini-Cassia area. The disease pattern is consistent with a seed-borne source of the pathogen. The field in question had received fungicide applications and lesions could not be found in any adjacent fields. The field is scheduled to be killed today. Based on this fact and the absence of thundershowers, the probability of field to field spread is very low. If growers have been applying fungicides with activity against late blight then additional applications are not needed. Fungicides active against late blight include (but are not limited to) standard protectants (chlorothalonil and EBDC based products), strobilurins, Omega, and Gavel. Endura is not effective against late blight.
This finding underscores the importance of buying clean seed and scouting. Even though the weather has not been favorable for late blight development, the disease can get started inside a potato canopy if inoculum is present.
If you have questions or concerns please contact Jeff Miller at 208-431-4420.
Update on corn earworm
Corn Treasure Valley - Idaho
Posted on: July 24, 2008 by Jerry Neufeld
The University of Idaho CIS 366 entitled “Timing Corn Earworm Control,”states that summer moths will begin laying eggs in fresh corn silk at approximately 1300 growing degree days (GDD). Egg hatch and larvae attack will begin about 73 GDD later.
According to the Oregon State University GDD model for Corn Earworm (http://pnwpest.org), we are currently at 1136 GDD in the Caldwell area, 1076 GDD in the Nampa area and 1297 GDD in the Parma area. We will hit 1300 GDD in the Caldwell area on 8/1, in the Nampa area we will hit 1300 GDD on 8/2, and in the Parma area we hit 1300 GDD on 7/24. Those fields with fresh silk at 1300 GDD are most vulnerable to attack from corn earworm larvae.
Stripe Rust in Moreland Winter Wheat, Ririe
Small Grains Eastern Idaho
Posted on: July 23, 2008 by Juliet Windes
While small amounts stripe rust had previously only been confirmed in the Treasure Valley, yesterday I found it in Moreland hard red winter wheat in Ririe, ID. It was a significant infection, occurring on about 30-40% of the total leaf surface. The crop was in late milk to early dough, and it was too late to spray fungicides. In addition to significant stripe rust, there was about 30% white heads forming from foot rot fungi, probably take-all. Black chaff was also prevalent.
Addtional surveys will be conducted to see if the fungi have moved beyond the winter wheat fields into adjacent susceptible spring wheat. At this time, I consider this to be an isolated incident. Early season conditions were extremely conducive to the development of the disease, but there was no reported stripe rust. Spread of the current infection from this focus should be limited due to hot, dry weather conditions.
Information on control and effective fungicide treatments is availbale on our cereals website: http://www.ag.uidaho.edu/scseidaho/ then click on "Publications" for Plant Disease Management Reports, "Cereal Diseases" and / or "Routine Fungicde Yield and Economic Data".

Posted on: July 23, 2008 by Jerry Neufeld
Lynn Jensen from the OSU Malheur County Extension office is reporting that Iris yellow spot virus has been confirmed in a bulb onion crop in the Nyssa and Ontario, Oregon areas. Make sure fields are maintained at an adequate fertility level, and that the soil moisture level is kept at about the 20 centibar level. Make thrips control insecticide applications every 7 - 10 days.
