BIOCONTROL EFFICACY OF BACTERIAL ANTAGONISTS IN THE MANAGEMENT OF SHEATH ROT DISEASE OF RICE
1Krishi Vigyan Kendra,
Pechiparai - 629 161, India
ABSTRACT
Rice is affected by number of fungal, bacterial and viral diseases. Among the fungal diseases,
sheath rot caused by Sarocladium oryzae has been reported to cause considerable loss in yield.
Bacterial biocontrol agents viz., Pseudomonas fluorescens (Pf1) and Bacillus subtilis have been
formulated in different carriers viz., gypsum, peat soil and talc powder. Their longevity and biocontrol
efficacy against sheath rot incidence were assessed under artificially inoculated condition. The results
revealed that gypsum based formulation of two bioagents were effective in controlling the disease by
recording the disease incidence of 10.67 per cent and 12.00 per cent respectively. Under field condition
also, gypsum based formulation of these biocontrol agents were found to be more effective in controlling
sheath rot incidence than the talc and peat based formulations
