ABSTRACT
Seven fungicides viz., Current M-45, carbendazim, copper oxychloride, copper hydroxide, propiconazole, hexaconazole, difenoconazole were evaluated against Fusarium solani (Mart.) Sacc. and Alternaria alternata (Fr.) Keissler in vitro. Among seven fungicides, total inhibition was achieved due to 0.2 per cent Current M-45, 0.05 per cent propiconazole and 0.2 per cent copper hydroxide against Alternaria alternata. In a field it was found that Contaf (0.05%) was most effective followed by mancozeb (0.3%) and Bavistin (0.2%) when applied four times at 15 days interval starting from 30 DAT. These fungicides were not only effective in controlling blight disease of chili but also resulted in producing significantly higher yields.
Key words :
Alternaria alternata, leaf blight, Capsicum annuum, chilli, fungicides, management.
