Head blighting potential ofFusariumspecies associated with spring wheat heads

Abstract
Seven Fusarium species isolated from spring wheat heads were tested for pathogenicity. Only F. graminearum and F. culmorum caused severe blighting of wheat heads following inoculation in the greenhouse. F. tricincium, F. sporotrichioides, F. equiseti, F. acuminalum, and F. poae did not blight heads but sometimes caused damage to inoculated spikelets.
