Abstract

Efficacy of two antagonists, namely, Trichoderma harzianum and Pseudomonas fluorescens was evaluated against brown spot of rice under field conditions. Three sprays of P. fluorescens (Talc based) at weekly interval @10g per litre, proved effective in reducing the disease severity and increasing the yield. It reduced the severity from 35.8 percent to 24.5 percent in case of rice variety PR116 and from 20.1 percent to 8.5 percent in case of Basmati rice 386.
