Abstract: Rice blast caused by Pyricularia oryzae cave continues to be a major constraint in rice production. Since, the existing chemical control measures being costly and may favor development of resistance in pathogens, the potential alternative methods have been explored in the present studies. Bio control agents Trichoderma viride, T. harzianum, Pseudomonas fluorescens and botanicals neem oil and neem oil + neem leaf extract (Azadirachta indica) were evaluated their efficacy against blast of rice (Pusa Basmati 1121). Carbendazim was used for standard check fungicides for comparison. The results concluded that the P. fluorescens inhibit the blast (21.99%) as compared to treated and untreated control (18.57% and 34.15 %, respectively) when T. viride is best bio-control (24.53%) which was followed by T. harzianum (23.08%) neem oil (26.20%) and neem oil + neem leaf extract (24.15%) inhibit the blast respectively.
