Pacific Northwest wheat producers experience harsh stripe rust year.

Stripe rust in wheat has become a major problem again this year, with pressure continuing across the region and continuing to build, report Oregon State University researchers.

Producers are wondering how to treat this year's crop, and how to plan for planting the next wheat in view of a continuing stripe rust threat. Oregon State University Extension Cereal Specialist has some observations of how certain varieties did during the 2010-11 season.

Stripe rust build incessantly this year across much of Oregon and in other parts of the Pacific Northwest. Varieties which held up well included ORCF 101 and Skiles, according to OSU Extension Cereal Specialist Michael Flowers.

Producers may want to  visit their Extension offices for a copy of the OSU Varieties and Stripe Rust pamphlet which offers an insight into how varieties performed in 2010 and 2011 observations. The information provided by Flowers shows these variety results on whether the wheats provided good, intermediate or poor stripe rust resistance:

Flowers urges growers not to let stripe rust get ahead of them. Maintaining good control as soon as possible can save money and yields down the road.   Once wheat reaches the flowering stage it is too late to have effective fungicidal control, researchers warn.

If the treatment window is passed, there is little use in applications of fungicide.
