10903. Weller, D.M., R.J. Cook, E.N. Bassett, R.L. Powelson, and R.R. Peterson. 1986. Rhizoctonia root rot of small grains favored by reduced tillage in the Pacific Northwest.. Plant Disease 70:70-73.
The first field identification of Rhizoctonia root rot of wheat and barley was made in eastern Oregon and Washington at six different locations. At all sites where the disease occurred, the wheat or barley was either direct drilled into stubble, sown with minimum tillage, or sown the same day the soil was tilled. In experimental plots with winter wheat, there were 9.9, 2.8, and 1.4 patches per treatment in which no-till, reduced till, and conventional till, respectively, were practiced.
