Abstract: This handbook is intended as a ready reference guide to the control and management tactics for the more important plant diseases in the Pacific Northwest.
Small Grain Seed Treatment Guide (MT199608AG) (pdf)
Abstract: Seed treatments promote seedling establishment and help reduce yield and quality losses due to many pathogens and insects. The ability of seed treatments to control fungal diseases has made them a great success story of disease prevention.
Soilborne Fungal Diseases
Abstract: Cephalosporium stripe (fungus stripe) is a vascular wilt-type disease of wheat and barley, which also affects other cereals and grasses. It is caused by the soilborne fungus Cephalosporium gramineum. ln autumn, the fungus produces millions of bacteria-sized spores (conidia), which are washed into the soil around the plant. These spores are the structures that will eventually infect the plant.
Controlling Root and Crown Diseases of Small Grain Cereals (PNW639)
Abstract: Farming systems, equipment, climate, topography, and crops vary widely in the Pacific Northwest. Because of this complexity, managing root and crown diseases of cereal crops is not always simple or straightforward. Recommendations are usually part of a system-wide approach based on the fundamental practices described in this publication.
Small Grain Root and Crown Diseases (MT201007AG) (pdf)
Abstract: Root and crown rots often go unnoticed, reducing yield until large patches of fields are missing plants or white, empty heads appear at crop maturity. Best management practices occur at planting and include using a seed treatment, crop rotation, and variety selection. There are no curative treatments for root and crown diseases. Positive identification and specific management recommendations for root and crown diseases can be obtained from your local county Extension office.
Snow Mold Disease of Winter Wheat in Washington (EB1880) (pdf)
Abstract: Snow mold diseases of wheat are some of the most dramatic and devastating diseases of plants. In the Pacific Northwest, the snow molds are important in areas where snow falls on unfrozen or lightly frozen soil and persists for 100 days or more.
Strawbreaker Foot Rot or Eyespot of Wheat (EB1378)
Abstract: Strawbreaker foot rot, which is also called eyespot, is a common and serious disease of winter wheat throughout most of eastern Washington, especially in the high rainfall regions. Yield loss varies considerably depending upon when plants are infected and the percentage of plants infected, but can range up to 50% in commercial fields when disease is severe.
