Abstract: Efficacy of two non systemic (thiram and mancozeb) and three systemic fungicides (carbendazim, tebuconazole and carboxin+thiram) each at five different concentrations were tested against Aspergillus niger, Sclerotium rolfsii and Rhizoctonia bataticola under in vitro conditions. Among the five fungicides tested mancozeb, tebuconazole and carboxin+thiram gave 100% inhibition against all the three test pathogens. Carbendazim was ineffective against Sclerotium rolfsii at 1000 ppm. Thiram showed 100% inhibition against Rhizoctonia bataticola at 5000 ppm.

Keywords: Aspergillus niger, Sclerotium rolfsii, Rhizoctonia bataticola, systemic and non systemic
