Bunts and Smuts of Cereals

Plain text source: 
The zero or very low tolerance levels at receival centres can make diseased grain only saleable as low value stock feed... Infection of seedlings is favoured by earlier sowing as the fungus prefers drier soils and temperatures of 15-21 C. The fungus grows systemically within the plant, usually without producing symptoms, and then it replaces the young grain with its own spores... Covered smut of barley can be effectively controlled by using fungicide seed treatments every year...
