Symptomatology of Colletotrichum disease of cocoa in India
Colletotrichum disease of cocoa is widespread in India. The symptomatology of the disease was studied during a survey of cocoa gardens in Kerala, Karnataka, and Tamil Nadu states. The disease causes three types of foliar symptoms viz., leaf blight, shot hole and irregular leaf spot, and rottings of cherelles and young pods. Repeated isolations of the pathogen from the affected parts of the plants collected from various gardens have shown that the pathogen was Colletotrichum gloeosporioides (Penz.) Sacc. Pathogenicity of the isolates was established on cocoa seedlings through artificial inoculation experiments. In all the cases the symptoms of the disease could be reproduced on the leaves of seedlings. The isolates from pods produced only leaf blight and shot hole symptoms on artificial inoculations.
