Abstract:

Under laboratory conditions using dual culture techniques, bio-control agents (Trichoderma viride, T. harzianum, Pseudomonas fluorescens and Bacillus subtilis) were tested against Bipolaris oryzae the causal organism of brown spot of rice. Maximum inhibition (65.33 %) of mycelial growth of B. oryzae was caused by T. harzianum, followed by T. viride (57.76%) and P. flourescens (32.68%). Under field conditions three rice varieties, Basmati-370, Jaya and PC-19, were used to test the bio-control agents, T. viride, T. harzianum and P. fluorescens each at 1×109 cfu/ml concentration. The foliar application of T. harzianum exhibited maximum disease reduction (64.00%) and also resulted in increased yield in PC-19 (8.00%) as compare to their respective control.
