Integrated Management of Rice Sheath Rot Incited by sarocladium Oryzae

In the field trial conducted during Kharif season, spraying at booting stage (85DAS) and 15 days later with carbendazim (500 g/ha) + phosphamidon (1 lit./ha) was the most effective in reducing sheath rot disease incidence, besides giving the maximum yield. Among the plant products and antagonists, neem oil (3%) spray had the maximum efficacy in reducing the disease incidence followed by neem seed kernel extract (5%), Pseudomonas fluorescens (1 kg/ha), Bacillus subtilis (1 kg/ha), leaf extracts (10%) of Acalypha indica , Convolvulus arvensis and in the Rabi season experiment also, the same trend was observed. The maximum cost benefit ratio was recorded in P. fluorescens sprayed plots.
