Stripe rust - Forecast and Update, March 1, 2020, Xianming Chen
Posted on: March 2, 2020 by Juliet Marshall
Quick Summary:
Stripe rust forecast for the PNW is at a severe epidemic level.
Areas in southern and eastern Idaho are not in the same forecast zone; Northern Idaho and the Palouse may not follow the exact same forecast or disease pattern.
It is still important to be aware of varieties that are susceptible - we will post alerts when stripe rust first appears. Please share sitings with us! (jmarshall@uidaho.edu)
Fungicide application with herbicide application is recommended for susceptible varieties.
Please read Dr. Chen’s email below for details.
Stripe Rust Forecast and Update, March 1, 2020
Xianming Chen
Stripe rust is forecasted to be in the severe epidemic level in the eastern Pacific Northwest
Based on the prediction models using the weather data from November 1, 2019 to February 29, 2020, wheat stripe rust is forecasted to be in the severe epidemic level range (40-60% yield loss) in the 2020 growing season. The models predicted highly susceptible varieties to have 44% to 53% with an average of 48% yield loss. This number is higher than the 44% forecasted in January based only on the November-December weather conditions. According to this prediction, susceptible and moderately susceptible commercially grown varieties will likely to have up to 24% yield losses.
Stripe rust was found in eastern Washington and Oregon
On February 26, we were checking wheat fields in Lincoln, Douglas, Grant, Adams, Franklin, Benton, and Walla Walla counties of Washington. Wheat was still dormant in Lincoln and Douglass counties, but has started growing in other counties, especially in Benton and Walla Walla counties. We found one leaf with active stripe rust (Figure 1) in a field in Lincoln County, where we easily found stripe rust in last November. We did not found rust in Douglass County, even in the fields where we were easily found stripe rust in last November. No stripe rust was found in other counties, except in our experiment field near Walla Walla. When we arrived at the field, it was already dark but we managed to found stripe rust on the susceptible check variety with cell phone light. One spot had 3-4 leaves producing active rust spores (Figure 2).
Figure 1. Stripe rust observed in a winter wheat field between Creston and Wilbur (Lincoln County), Washington on February 26, 2020.
Figure 2. Stripe rust found in a disease monitoring nursery near Walla Walla, WA on February 26, 2020.
On February 26, Christina Hagerty found active stripe rust on the same highly susceptible wheat variety in our stripe rust monitoring nursery planted in Pendleton (Umatilla County), Oregon (Figure 3).

Recommendations for the Pacific Northwest
As the stripe rust has started, management of the disease on winter wheat should start at the time of herbicide application based on the stripe rust ratings in the Seed Buying Guides (such as http://washingtoncrop.com/wp-content/uploads/2019/09/2019-portrait.pdf). For fields planted with varieties rated 5-9 (such as Keldin, LCS Jet, WB4311, Curiosity CL+, Eltan, UI Magic CL+, Xerpha, and ORCL 102), fungicide should be used at the time of herbicide application. For fields planted with varieties rated 4, scout the fields and use fungicide at the time of herbicide application only when active rust is found. For fields planted with varieties rated 1-3, fungicide is not needed.
As stripe rust will be likely severe, planting spring varieties with ratings 1 to 4 may void using fungicide.
Stripe rust in the country
In addition to Oregon and Washington, stripe rust has been reported in Louisiana.
2020 Dormant Oil Spray on Fruit Trees
General Landscape and Garden Treasure Valley
Posted on: February 24, 2020 by Maria Held
With the unusually mild winter and expected warm temperatures this week the buds on fruit trees (especially apricot) are swelling. It is time to apply dormant oil after pruning the trees. This will prevent insect problems for the coming season like aphids and scale.

Soil Amendments
Wildlife, Domesticated Animals, and Land Use
Agricultural Water (Part I: Production Water; Part II: Postharvest Water)
Postharvest Handling and Sanitation
How to Develop a Farm Food Safety Plan
In addition to learning about produce safety best practices, key parts of the FSMA Produce Safety Rule requirements are outlined within each module. There will be time for questions and discussion, so participants should come prepared to share their experiences and produce safety questions.
Benefits of Attending the Course
The course will provide a foundation of FSMA Produce Safety Rule requirements and details on how to develop a farm food safety plan. Individuals who participate in this course are expected to gain a basic understanding of:
Microorganisms relevant to produce safety and where they may be found on the farm
How to identify microbial risks, practices that reduce risks, and how to begin implementing produce safety practices on the farm
Parts of a farm food safety plan and how to begin writing one
Requirements in the FSMA Produce Safety Rule and how to meet them.
After attending the entire course, participants will be eligible to receive a certificate from the Association of Food and Drug Officials (AFDO) that verifies they have completed the training course. Participants must be at least 14 years of age to receive the AFDO certificate. To receive an AFDO certificate, a participant must be present for the entire training and submit the appropriate paperwork to their trainer at the end of the course.

With no rainfall for a few weeks and none in the forecast make sure to water you landscape at least one more time before winter. It is important for anything planted this year especially trees and shrubs. This will give your plants the best possible start next spring and make them less susceptible to pests and diseases.

Potato Sustainability Initiative Survey
Posted on: October 25, 2019 by Nora Olsen
Updated manual and resources now available to help navigate the
2019 Potato Sustainability Initiative (PSI) survey
Potato growers—you will soon be asked to answer the annual Potato Sustainability Initiative (PSI) survey. Most process, and some fresh, growers are requested to participate in the PSI sustainability survey. Please note: there will be no audit for the 2019 survey.
In the past, approximately 20% of the growers who completed the survey were audited each year. The audit involved an interview between the grower and auditor with specific questions and an inspection of documents. A manual was developed to help growers methodically and successfully gather required documents for the audit, with examples of standard operating procedures, and resources to help answer interview questions. Audit information was retained in the manual as a reference and resource for future audits.
The manual is posted at https://www.uidaho.edu/cals/potatoes/food-and-farm-safety
The 2019 survey changed slightly from the 2018 survey.
The manual was developed by University of Idaho, Washington State University and IACI with funding from the NW Potato Research Consortium.
Fall spray for shothole disease and peach leaf curl

Coryneum blight (shothole disease), Taphrina deformans (peach leaf curl)
Posted on: October 22, 2019 by Maria Held
Prevent new coryneum blight (shothole) infections this fall by applying copper to trees when 50% of the leaves have fallen. The disease affects all stone fruits but is mainly a concern in apricot, nectarine and peach.
As peach trees lose their leaves you need to spray for peach leaf curl if you experienced the disease this spring.
