Colletotrichum crassipes associated with cocoa wilting in Bahia, Brazil
The association of Colletotrichum crassipes (Speg.) v. Arx. with cocoa (Theobroma cacao L.) wilt disease is described. The pathogen was first isolated from roots of the cocoa clone SIAL-698 showing wilting symptoms, at the Jucari Experimental Station, Bahia. The main symptoms of the disease were drooping, gradual yellowing, withering and drying of the leaves followed by death of the tree. The pathogenicity of C. crassipes was proved on cocoa seedlings by different methods of inoculation. The inoculated seedlings died within 1 month. The fungus also induced pod-rot and leaf spot on cocoa and was more pathogenic to pods and leaves than C. gloeosporioides. In comparison to C. gloeosporioides, C. crassipes formed different types of colonies on culture media, its conidia were slightly longer with sclerotia being found in abundance
