Abstract
Chilli (Capsicum annuum) is one of the most important solanaceaus crop in India. Chilli crop affected by a large no of foliar disease. Among them, chilli anthracnose caused leaf blight and fruit rot is one of the most important diseases causing heavy yield loss. Hence, an efficient research studies carried out related to management of agricultural important pathogen of chilli crop. Under in-vitro study seven chemical namely silver Nanoparticle (AgNPs), AgNO3, Silvox(H2O2 + AgNO3), Chitosan, Salicylic acid, H2O2, Isoprotiolane(check chemical) were evaluated in different concentration against fungal pathogen Colletotrichum capsici, under in-vitro and in-vivo condition. In in-vitro condition out of seven chemical H2O2@ 9.66 ppm appeared to be most effective which was followed by Silvox (12.07 ppm) in respect of mycellial growth inhibition against Colletotrichum capsici as compared to check chemical Isoprothiolane. In-vivo condition it recorded that curative application of nano-formulation resulted significant disease suppression at 50ppm (Silver Nanoparticle-(AgNPs)-80.96%, AgNO3-60.0%, Silvox-84.01% and Chitosan-61.93%) as compared to check chemical Isoprothiolane (57.93%)at 50ppm.
