ABSTRACT

A field study has been conducted at Horticulture Research and Extension Station, Devihosur on the management of fruit rot of chilli caused by Colletotrichum capsici using 7 treatments in 3 replications following Randomized Block Design. Chlorothalonil @ 0.32% recorded significantly least PDI (12.67%) than all other treatments and it was found on par with Chlorothalonil @ 0.21% and Chlorothalonil @ 0.13% (13.23% and 13.28% PDI respectively). Yield was found maximum in Chlorothalonil @ 0.32% (10.97 q/ha) than all the treatments and it was found on par with Chlorothalonil @ 0.21% (10.03 q/ha) and Chlorothalonil @ 0.13% (9.40 q/ha). No phytotoxicity symptoms were observed at all stages of crop growth by the application of Chlorothalonil.
