6370. Smiley, R.W.. 1990. Seed treatment fungicides for wheat and barley.. Sherman Station Field Day handout, OSU, Moro, OR.
Seed applied fungicides failed to improve yields of winter wheat or were inconsistent from site to site and/or year to year. The most consistent treatment for winter wheat was a combination of Apron and Vitavax 200. This mixture increased wheat yields by 3%. Fall barley yields were either unchanged or reduced, while spring barley showed the best economic response. Thus, an economic response to seed treatment is unlikely in the absence of damaging amounts of smut disease. Since control of smut depends on the combination of fungicide seed treatments and genetic resistance, which has been stable for decades, the use of untreated seed is discouraged to avoid the loss of genetic resistance by cereal cultivars.
