Cephalosporium Stripe Disease of Cereals (EB1434) (pdf)
Abstract: Cephalosporium stripe (fungus stripe) is a vascular wilt-type disease of wheat and barley, which also affects other cereals and grasses. lt 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) (pdf)
Abstract: This information is designed for wheat and barley producers in the Pacific Northwest. Some recommendations can be applied only in wetter areas or irrigated systems, where diverse crop rotations can be used to reduce pathogen populations. Many recommendations are also applicable in low-rainfall, fallow-based systems. Apply as many of the following practices as possible to minimize yield loss and other negative effects from diseases that attack roots, crowns, and lower stems.
Guide to Common Root and Crown Diseases of Cereal Crops in Montana (pdf)
Abstract: A guide to common root and crown diseases of cereal crops in Montana.
Rhizoctonic Bare Patch and Root Rot – Distribution and Management (pdf)
Abstract: Rhizoctoniais a fungus that attacks the roots of wheat and barley, causing root rot and subsequent economic loss for producers. In the dryland wheat cropping area of the inland Pacific Northwest, there are two primary species—Rhizoctonia solani AG-8 and Rhizoctonia oryzae (also known as Waitea circinata). Young seedlings are especially susceptible to these root-infecting fungi. We find more damage in spring-planted wheat, because the disease is more severe under the cool, wet soil conditions that are often present in the spring.
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 (PNW), 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.
