Abstract:
Groundnut is an important oilseed crop of India, grown extensively in various parts of the country. Stem rot caused by (Sclerotium rolfsii Sacc.) is the major disease, affecting the groundnut cultivation across the India and worldwide. Control of this pathogen is difficult as it produces sclerotia which overwinter in the soil to emerge as inoculum and cause the disease in following season. The main aim of this study was to evaluate the fungicides against stem rot of groundnut under in vitro conditions. Out of four fungicides screened, 100 per cent inhibition of S. rolfsii was observed with thiram and tebuconazole at both recommended and half the recommended dosages. Whereas, carbendazim and azoxystrobin recorded 76.29% and 89.07% respectively at the recommended concentration and at half the recommended concentration carbendazim and tebuconazole were recorded 34.29% and 83.14% respectively. The present findings suggest that thiram and tebuconazole were highly effective at recommended and half the recommended dosages.
