Survival and Spread . Survives on infected straw and stubble, on wild grasses, and rarely on seed. Spores are airborne and also spread by splashing rain. Other Crops Affected. Bromegrass, rye and wheat grass.
Varieties vary in susceptibility.
Check variety information publications for susceptibility to leaf spot fungi. Crop rotations or burying crop refuse by tillage reduces early infection but may not prevent late infection. Early applications of mancozeb or propiconazole fungicides may protect the tillers from early infections. Both fungicides have good activity against leaf spots on wheat. Late in season large numbers of spores may be blown considerable distances.
