Abstract:
Efficacy of bio-agents and fungicides namely Trichoderma viride, Pseudomonas fluorescens, Chlorothalonil, Aazoxystrobin, Mancozeb and Thiabendazole was evaluated against Alternaria blight of chickpea under field condition. In field condition bio-agents and fungicides were used as seed treatment. Trichoderma viride @ 5g/litre as seed treatment (ST), Pseudomonas fluorescens @ 5g/kg as seed treatment (ST), Thiabendazole @ 2g/kg as seed treatment, Mancozeb 3g/kg as seed treatment, Chlorothalonil 2g/kg as seed treatment and Aazoxystrobin 5g/kg as seed treatment. Mancozeb 3g/kg as seed treatment was found effective with less disease severity of 23.09%. The effect of different antagonist’ viz. Trichoderma viride and Pseudomonas fluorescens were evaluated against different Alternaria blight of chickpea by dual culture technique. Among Bio-agents Trichoderma viride (49.08%) followed by Pseudomonas fluorescens (41.84%) over control were found effective in controlling the Alternaria blight. Among the fungicides, Mancozeb was highly effective in inhibiting the growth of Alternaria alternata as it produced 55.27% growth inhibition at 5% concentrations. All bio-agents and fungicides were found effective in reducing the disease severity.
