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, major soil borne pathogens of groundnut 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.
