Plant Disease Management Handbook

Cause The fungus, Tilletia indica, which can be introduced in contaminated seed. The fungus may become established as persistent spores in soil. It is not currently known to be in Pacific Northwest soils. If it or the disease were detected in locally produced wheat, the industry could suffer serious economic damage because the fungus is strictly regulated in international and domestic seed and grain trades.

Cause Several species of Fusarium can cause scab, including: F. graminearum, F. avenaceum, F. culmorum, and Microdochium nivale (formerly Fusarium nivale).

Cause The fungus, Urocystis agropyri, which overwinters as spores on seed or in soil. It infects wheat before seedlings emerge. Spores may survive several years in soil.

Wheat (Triticum aestivum) - Common Root Rot (Seedling Blight)

Cause The fungus, Claviceps purpurea, attacks barley, oats, rye, triticale, and numerous wild grasses as well as wheat. The hard black sclerotia of the fungus germinate to produce stromata, which form ascospores carried by wind or insects to the flowering cereal. A conidial stage, called honeydew, forms on the infected head; insects can transmit the honeydew to uninfected flowers. Sclerotia formed on the heads drop to the ground or are mixed with seed for the next year.
