Stripe Rust

From Juliet Marshall

‍With the spring weather perfect for small grain production, it is no surprise that stripe rust was finally confirmed in southern Idaho. The breeding line was significantly infected, but isolated (that is, infections were not widespread in the field). Most of the plots were just past flowering, and there is a long way to go for the winter crop to finish.

We are about 10-14 days behind previous years according to growing degree day estimates. Be sure to check plant growth stage prior to shutting off irrigation. You don't want to shut off irrigation too soon or too late - remember the general rule of thumb of "Full soil profile of moisture at soft dough before water shut off."We are mostly past the window of application for fungicides for winter wheat, and the stripe rust disease pressure is low. The greatest threat will be for susceptible spring wheat varieties. Scout spring wheat fields for infection, and report infections to University of Idaho personnel in order for us to track and report new occurrences.

Fungicide applications will likely not be required for moderately resistant and resistant varieties. Fungicides on the market are equally effective as stripe rust protectants, but as the flag leaves emerge, do not use strobilurin fungicides as that increases risk for DON contamination in grain from FHB or scab infection.  Remember to read and follow all label directions.

U.S .Wheat Associates Sees Positive Outcome at WTO Ministerial Conference
To misquote Mark Twain, reports of the death of agricultural negotiations at the World Trade Organization (WTO) are exaggerated. That is a key message for the world’s wheat growers and buyers following the Thirteenth WTO Ministerial Conference (MC13) in Abu Dhabi, United Arab Emirates. “Going into MC13 negotiations, we did not want to see any backsliding on past progress made on agricultural commitments at the WTO,” said U.S. Wheat Associates (USW) Director of Trade Policy Peter Laudeman, who joined a coalition of U.S. agricultural representatives at the Conference. “Fortunately, the U.S. negotiating team and many other countries were able to hold firm, particularly against India’s protection of its trade-distorting wheat and rice policies.”

How does using SRC testing to improve wheat quality?
Because the quality and attributes of flour can vary by season and variety, it’s important for bakers to understand what works best in their products. One tool that can help them determine flour quality is Solvent Retention Capacity (SRC) testing, said Sean Finnie, director of the Western Wheat Quality Laboratory with the US Department of Agriculture’s (USDA) Agricultural Research Service. He is part of a team that works to improve wheat quality by identifying desirable traits, testing for them and working with breeders to enhance those traits.

Analyzing Idaho crop input costs and 2024 projections
Understanding what operating costs will look like in 2024 is crucial for farm businesses. This article provides a background discussion on categories of operating costs of the greatest importance for crops grown in Idaho and an assessment of the 2024 operating cost projections from the USDA Economic Research Service (ERS). The first part provides insights regarding the input prices that can have the greatest influence on a farm business’ profitability.

Snowpack improves in much of Idaho
A wet February and early March have boosted snowpacks in much of southern Idaho, where some flood-control operations are planned in coming weeks. Snowpack in the state’s northern areas remains below 30-year medians partly because the dominant El Nino weather pattern pushes Pacific storms south. An anticipated shift to La Nina patterns, expected in late summer and early fall, will bring more rain and snow in northern areas.

What's Holding Back U.S. Hard White Wheat in World Markets
A wheat variety introduced just 34 years ago shows great promise for United States wheat producers to better compete in world markets, if some challenges can be overcome. Hard white wheat was created as a distinct wheat class in 1990. A very close genetic cousin of hard red winter wheat, its main difference is that it lacks the red coloring in its endosperm. That red color imparts a taste to flour made with hard red winter wheat that some consider more “wheaty” or even bitter. Hard white wheat flour can have slightly less protein than hard red winter wheat, although its protein content is still much higher than traditional refined white flour.
