Abstract: In vitro efficacy of fungicides viz., carbendazim 75 WP, propiconazole 25 EC, metalaxyl 35 SD and azoxystrobin 23 SC and bio-agents viz., Trichoderma viride and its mutants (TVM1 and TVM2) and Pseudomonas fluorescens were tested against Alternaria helianthi causing leaf blight of sunflower. Among the fungicides propiconazole @ 0.1% was found most effective followed by carbendazim @ 0.2% and azoxystrobin (0.05%). Among the bio-agents Trichoderma viride Mutant 1 (TVM 1) was proved as best bio-agent against test pathogen followed by Trichoderma viride mutant 2 (TVM 2) and mother culture of Trichoderma viride.
