Evaluation of fungicides, botanicals and biocontrol agents against chilli anthracnose caused by Colletotrichum capsici

The efficacy of different chemicals, botanicals and bioagents was tested against anthracnose of chilli pathogen, Colletotrichum capsici. Two chemical fungicides viz. Captan and mancozeb, two botanicals viz. garlic and neem, four combination treatments viz. Captan + neem extract, mancozeb + garlic extract, Trichoderma harzianum + Captan and Pseudomonas fluorescens + carbendazim were tested at five concentrations. The fungicide Captan at 600 ppm was found most effective with 79.50% mycelial growth inhibition followed by mancozeb 66.20%. Neem extract at 600 ppm resulted in maximum (57.20%) mycelial growth inhibition followed by garlic extract (53.83%). Among the fungicides and plant extract combinations Captan+ neem extract at 600ppm was found most effective with 76.35% inhibition. Among the biocontrol agents and fungicides combinations T. harzianum + Captan was found most effective at 600ppm with 77.27% inhibition. Among the biocontrol agents tested T. harzianum was found more effective with 50.89% inhibition than P. fluorescens.
