Pathogenicity of Myrothecium roridum and Rhizoctonia solani in nursery coffee plants

Abstract

Stem cankers and root rot of coffee plants were detected in the nurseries. Proliferation of adventitious roots at the base of the stems was also observed. Several fungi were isolated from the root and stem lesions and pathogenicity trials were conducted under the humid conditions of the shadehouse. Typical disease symptoms were reproduced by Myrothecium roridum and Rhizoctonia solani in the root and in the stem of the inoculated plants.
