To isolate, identify and prove pathogenicity of Colletotrichum capsici on chilli

Abstract

Chilli is a universal spice crop of India grown in almost all the states of the country. Anthracnose diseases occur on leaves, stems, and both pre and post-harvest fruits. On the basis of the characteristic symptoms of anthracnose disease, exhibited on naturally and artificially diseased foliage of chilli and cultural characteristics of the test pathogen isolated from naturally and artificially diseased foliage of chilli were found exactly similar. During the survey on incidence of anthracnose of chilli, minimum pooled mean disease incidence was found in Parbhani Tejas (16.61%) and maximum recorded with Local variety (31.84%). Varieties recorded mean pooled disease incidence was Green Gold (25.78%), Amulya (28.55%), Garima (22.90%), KSP 1194 (21.60%), Jwala (19.00%). Pathogenicity of Colletotrichum capsici was successfully proved on chilli plants under screen house condition.
