Research. Importance of the Husk Covering on the Susceptibility of Corn Hybrids to Fusarium Ear Rot. C. Y. Warfield, Graduate Research Assistant, University of California, Davis 95616. R. M. Davis, Cooperative Extension Specialist, Department of Plant Pathology, University of California, Davis 95616. Plant Dis. 80:208-210. Accepted for publication 6 November 1995. Copyright 1996 The American Phytopathological Society. DOI: 10.1094/PD-80-0208. The role of the husk covering and the influence of intra-ear thrips infestation on severity of Fusarium ear rot (Fusarium moniliforme) were evaluated in 1990, 1991, and 1992 among corn (Zea mays) hybrids previously rated as susceptible, intermediate, or resistant to Fusarium ear rot. For the three treatments imposed on individual corn ears in 1990, ears were either left untreated, wrapped with a strip of parafilm at the ear tip to maintain a tight seal, or husk layers were split open along one side of the ear 1 to 2 weeks after pollination to partially expose the developing kernels. In 1991 and 1992, two additional treatments, split husks followed by acephate insecticide application and insecticide application to ears with intact husks, were added. |
