Survival of Colletotrichum graminicola in Infested Corn Residues in Ohio. P. E. Lipps, Assistant Professor, Department of Plant Pathology, Ohio Agricultural Research and Development Center, Wooster 44691. Plant Dis. 67:102-104. Accepted for publication 16 June 1982. Copyright 1983 American Phytopathological Society. DOI: 10.1094/PD-67-102.

In the spring, the number of acervuli of Colletotrichum graminicola developing on corn (Zea mays) residues buried by fall plowing was significantly less than on residues left on the soil surface. Although a relatively low level of sporulation occurred on rind sections of buried stalks, acervuli developed on 30% of the stalks that were buried and left to overwinter. C. graminicola was eliminated from infested corn stalks buried 12 cm below the soil surface from 10 December to 18 August.
