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

Chickpea (Cicer arietinum L), wilt caused by Fusarium oxysporum f.sp. ciceri was first reported from India in 1918. ln the recent years, the biological control has received a worldwide attention and is being integrated effectively with other pesticides. The efficacy of two species of fungal bioagents such as Trichoderma viride, Trichodermo harzianum and two sps of bacterial bioagents such as Pseudomonas fluorescens and Bacillus subtilis were evaluated against Fusarium oxysporum f.sp. ciceri in vitro condition using Dual Culture Technique. The highest per cent growth of inhibition of observed Trichoderma harzianum (76.66%) followed by Bacillus subtilis (63.14%). The lowest growth inhibition was observed in Pseudomonas fluorescens (53.52%).

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.
