Occurrence of seed borne pathogens in Chilli (Capsicum frutescence L.) cv. GVC 111 in vitro

Abstract

An experiment was to know the occurrence of seed borne pathogens in chilli in vitro. Chilli (Capsicum frutescence L.) is mainly cultivated for its vegetable green fruits and for dry chilli as the spice of commerce. Chilli is affected by various fungal seed borne pathogens, which affected in chilli yield production. Occurrence of seed borne pathogen was carried out by two different methods viz., Standard blotter paper method and Potato Dextrose Agar (PDA) method. In standard blotter paper method A. niger was found dominant fungus in sterilized and unsterilized seeds and in PDA method per cent disease incidence was not recorded in sterilized seeds by A. niger, A. flavus, Fusarium sp., Rhizopus sp., Colletotrichum capsici and Penicillium sp. while maximum per cent disease incidence A. niger was found in unsterilized seeds.
