Stripe Rust Forecast and Update

Stripe rust is forecasted to be in the moderate epidemic level in the eastern Pacific Northwest Based on the predication models using the weather data from November to February, wheat stripe rust is forecasted to be in the moderate epidemic level range (20-40% yield loss) in the 2022 growing season.  The models predicted highly susceptible varieties to have 33% yield loss with a standard deviation of 7%.  This value is similar with the 34% forecasted in January based only on the November-December weather conditions.  According to this prediction, susceptible and moderately susceptible commercially grown varieties will likely have 10 to 24% yield losses, or 8% yield loss on average for commercially grown varieties.   Stripe rust has not been found in eastern WashingtonSo far, stripe rust has not been found in fields of eastern Washington.  We checked wheat fields in Whitman, Adams, Lincoln, Grant, and Douglas counties on November 23, 2021; and Whitman, Garfield, Columbia, Walla Walla, Benton, Franklin, and Adams on March 1, 2022, but did not find any rust.  Stripe rust will likely to have a late start in the eastern Pacific Northwest. Recommendations for the eastern Pacific Northwest As stripe rust has not been found and the disease is likely to have a late start, fungicide application is not recommended in the early growth season at the time of herbicide application for winter wheat, unless stripe rust is observed in the fields. Fungicide application may be needed later in the flag leaf stage for fields planted with moderately susceptible and susceptible varieties (stripe rust ratings 6 – 9). For spring wheat, resistant or moderately resistant varieties (stripe rust ratings 1 – 5) should be selected for planting.

Wheat Poised for a Rally
With sharp escalations in Russia’s war against Ukraine, and less wheat leaving Black Sea ports, futures markets for wheat are climbing. Futures markets rose above $7 per bushel for the first time since 2023. Trading on futures and options can come with substantial risks, but knowing what your risks are and weighing possible outcomes can be profitable and help you manage your risk. The Idaho Wheat Commission invested grower dollars into the creation of the Idaho Wheat Commission Bill Flory Endowed Chair of Risk Management at the University of Idaho, held by Dr. Xiaoli Etienne.
