Necrotic spotting on the roots and coleoptile leads to death of seedlings. Leaf spots are circular or oval, up to 1 cm diam., with a dark margin; the centre becomes pale and bears the black sclerotia. Spotting occurs on the glumes, the kernels are invaded and become discoloured and shrivelled. Sclerotia are formed in all infected areas (27: 447)
