ABSTRACT
Test the efficacy of fungal and bacterial antagonistic formulations were controlling the seed borne fungi in seed samples of green gram and black gram collected from Pulse Research Unit, Akola were used for laboratory test. Seed treatment with talc based formulation of Trichoderma viride at 4 g/kg, Pseudomonas fluorescens at 10 g/kg and Bacillus subtilis at 10g/kg bio agents were tested for their efficacy against seed-borne mycoflora to improve seed germination and also recorded significantly incidence of seed borne fungi. Among this three bio agents T. viride was found superior in controlling the seed borne mycoflora (86.90%, 88.00%) and also maximum seed germination was observed in T. viride (67.60%, 71.00%), shoot length (8.91cm, 11.5cm), root length (7.10cm,9.15cm) and seedling vigour index (1119,1466) in green gram and black gram respectively.
ABSTRACT
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.
ABSTRACT
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.
