ABSTRACT
Finger millet is one of the important millet crops widely cultivated across India. Although, it is known to be one of the hardiest crops, is affected by many diseases, of which foot rot caused by Sclerotiumrolfsiihas been on the rise especially under irrigated and high rainfall situations.Nine Trichoderma spp. and 10 Pseudomonas spp. isolated from cultivated soils of Mandya, Karnataka, india were screened in in-vitro against S.rolfsii. Among the bio-agents Chandagaluisolate (CT) of Trichoderma and Kannahatty isolate (KP) of Pseudomonas were found to be very effective in suppressing the foot rot of finger millet in susceptible variety Indaf-5. These two potential bio-agents when tested in different delivery methods under greenhouse conditions, seedling root dip followed by soil application of Trichoderma (CT) and Pseudomonas (KP) were significantly superior over other methods in reducing foot rot incidence, besides enhancing seedling growth parameters and grain yield.
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.
