Online published on 12 November, 2021. Abstract Sclerotinia sclerotiorum is distributed worldwide and causes stem rot in Brassica as well as in 400 different plant species. This pathogen is not only soil borne in nature but also infects the plants as air and seed borne, and hence it's very difficult to manage. Thus, integrated crop management might be the only way to minimize the disease which includes collective approach of several management methods i.e. crop rotation, application of plant extract, bioagents, fungicides etc. Hence, a field experiment was conducted during Rabi 2018–19 & 2019–20 to manage the prevailing Sclerotinia stem rot of Indian mustard through integrated disease management approach. As observed from the field, the treatment combination, T4 [Seed treatment with Carbendazim (0.2%) + Foliar spray Carbendazim (0.2%)] was found most effective with 81.82% reduction in Sclerotinia disease over control followed by T6[Seed treatment with Carbendazim (0.2%) + Foliar Spray of Difenoconazole @ EC (0.1%)] with 78.84% Sclerotinia disease reduction. The above mentioned treatments seemed to increase the yield by 58.06% and 52.24%, respectively over control.
