Abstract :

Nine fungicides namely: carbendazim, mancozeb, captan+hexaconazole, chlorothalonil, propiconazole, difenoconazole, azoxystrobin and bioagents namely: Trichoderma viride and Pseudomonas flourescens were evaluated in vitro by using poisoned food technique and dual culture respectively for studying their effect on the inhibition of mycelial growth of C.capsici. Among these fungicides maximum inhibition on mycelial growth was observed in propiconazole (0.1%) and difenoconazole (0.1%) (100%) followed by captan + hexaconazole 0.1% with 86.66 percent growth inhibition over control. The fungicide carbendazim @ 0.05% recorded 75% inhibition. This was followed by mancozeb @ 0.2% which recorded 70% inhibition. Azoxystrobin @ 0.1% recorded 67.50% inhibition. The least inhibition (63.77%) was recorded in chlorothalonil @ 0.1%. In dual culture mycelial growth inhibition of 55.5% was recorded in T. viride. Pseudomonas flourescens recorded 90% mycelial growth inhibition of the pathogen
