Grains and field crops, Biosecurity, pests, weeds and diseases
Fungal staining (black point) of wheat can reduce the quality of grain. The most serious problem is a discolouration of products. Discolouration is a consequence of infection by microorganisms. The most likely cause in Western Australia is a species of the common fungus Alternaria. Infection and discolouration occur between flowering and grain maturity, and the optimum environmental conditions are probably consecutive days of high relative humidity together with warm temperatures.
