Evaluation of fungicides and bio-agents against Alternaria alternata causing Alternaria blight of chickpea (Cicer arietinum L.)

Abstract

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, Chlorothalonil was highly effective in inhibiting the growth of Alternaria alternata as it produced 55.27% growth inhibition at 5% concentrations, respectively. Mancozeb and Azoxystrobin were found effective as growth inhibitions about 51.54%, 42.23% respectively. Followed by Thiabendazole at 5 @ (37.33%). In food poison technique method.
