wheat
First found on stubble of wheat plants affected by foot rot in France, later isolated from wheat roots in England, best known, however, as the causal organism of milo disease of sorghum in U.S.A. Roots of susceptible sorghum plants are badly rotted and seedlings stunted, leaves tend to curl as if affected by drought. Crowns of diseased plants when split show a dark red discoloration. Plants may die as seedlings with the roots completely rotted or they may grow on though stunted until the time of heading when they begin to show signs of firing; the heads do not develop fully and the plants die just when grain of resistant plants is at the hard-dough stage.
