The incidence of Cephalosporium stripe was related to selected winter wheat management practices prevalent in the Palouse region of northern Idaho and eastern Washington in 1980. A study of rotation sequence, tillage method, cultivar, and the amount of nitrogen fertilizer applied was conducted in field plots seeded in a split plot, split block experimental design. Disease incidence was measured at the early milk stage and expressed as the percentage of tillers exhibiting symptoms of Cephalosporium stripe. The greatest differences in stripe incidence occurred among rotation and tillage factors. A 2-yr, winter wheat/spring pea rotation showed higher disease incidence than 3-yr rotations. Among tillage practices, Cephalosporium stripe was most severe in no-till and decreased progressively in minimal and conventional tillage plots.
