Efficacy of Bioagents Against Seed Borne Fungi of Rice.

The effect of different antagonist ’ viz. Trichoderma viride Pseudomonas fluorescens and Bacillus substilis were evaluated against different seed borne fungi of rice by dual culture technique. Among three bio agents Trichoderma viride (42.59 to 73.33%) followed by Bacillus subtilis and Psuedomonas fluorescens over control. Significant suppression of radial mycelial growth of Drechslera oryzae by Trichoderma viride, and Trichoderma harzianum in dual culture and Inhibition of Curvularia lunata causing black kernel in rice with Bacillus subtilis (97.77%) followed by Trichoderma viride (96.44%) and Trichoderma harzianum (93.50%) in dual culture method.

Efficacy of Bioagents Against Seed Borne Fungi of Black Gram.

The effect of different antagonists’ viz. Trichoderma viride, Pseudomonas fluorescens and Bacillus subtilis were evaluated against different seed borne fungi of black gram by dual culture technique. Among three bioagents, Bacillus subtilis exhibited maximum mycelial growth inhibition of Phoma medicaginis (73.70%), Fusarium solani (57.60%), Curvularia lunata (44.53%) followed by Pseudomonas fluorescens with Macrophomina phaseolina (62.41%) and Fusarium oxysporum (59.97%) respectively.
