CHRIS MUNDT CONCERNED ABOUT SHARP EYESPOT IN WHEAT

Sharp eyespot, caused by the soilborne fungus Rhizoctonia cerealis, can infect barley, wheat, and rye. According to the Pacific Northwest Plant Disease Management Handbook it overwinters as sclerotia in soil or debris as well as persisting as mycelium in crop residues. Cool, moist conditions at the plant's base favor infection. Chris Mundt, Professor in the Department of Botany and Plant Pathology at Oregon State University, says the disease has appeared in the Valley in small amounts in previous years but conditions this year have helped the disease spread.
