Abstract:
Chilli is susceptible to many foliar and soil borne fungal diseases of which fruit rot caused by Colletotrichum capsici is one of the most destructive disease which causes heavy yield loss in almost all chilli growing areas. A roving survey was conducted during the months of October- December 2021 in the chilli growing areas of erstwhile Khammam district i.e. Khammam, Sathupally and Bhadrachalam of Telangana and the disease incidence was assessed in different cultivars which are highly pungent, medium pungent and low pungent grown in these areas. The study revealed variations in per cent disease incidence of fruit rot in major chilli growing areas of erstwhile Khammam district. Highest disease incidence was recorded in Pinapaka village of Khammam area (89.0) followed by Mondikonta village of Sathupalli area (88.0). Of the 3 locations, minimum per cent disease incidence was observed in Erraguntapadu of Sathupalli (10.0). The results also shown that among the 19 isolates collected from the three chilli cultivars grown in the three mentioned chilli growing areas shown variations in the per cent disease incidence in the decreasing order of isolate C.c-3 (89) followed by C.c- 12 (88.0), C.c-13 (85.0), C.c-8 (83.0), C.c-18 (76.0), C.c-11 (74.0), C.c-16 (74.0), C.c-5 (72.0), C.c-4 (70.0), C.c-19 (68.0), C.c-10 (49.0), C.c-7 (43.0), C.c-1 (42.0), C.c-9 (26.0), C.c-14 (25.0), C.c-6 (24.0), C.c-17 (15.0), C.c-2 (12.0) and C.c-15 (10.0), respectively.
