Stem rot of rice, caused by Sclerotia oryzae is a serious threat to rice production in India. Fungicides only provide limited control of this pathogen but also have ill effects on the environment. In an attempt to develop better integrated strategies for management of this disease, a field study was conducted during rabi 2017-18 to evaluate the strategies of integration of effective fungicide Hexaconazole (0.2 %) and the bacterial antagonistic isolate P.F-4 which were effective against S. oryzae in vitro studies. Among the seven stratagies, the following integration strategies were statistically superior in managing the stem rot disease, Alternate sprays with Hexaconazole and P.F-4 (40.00 PDI, 7.56t/ha grain yield and 10.26t/ha straw yield) which was statistically at par with Seedling dip with P.F-4 and two sprays followed by two sprays with Hexaconazole (44.40 PDI, 6.95t/ha grain yield and 8.53t /ha straw yield) and Two sprays with Hexaconazole followed by two sprays with P.F-4 (48.35 PDI, 7.37t/ha grain yield and 7.73t/ha straw yield).While in Untreated control significantly higher stem rot disease was recorded with 67.83 PDI when compared with all other treatments.
