In vitro Evaluation of Antifungal Activity of Different Trichoderma spp. and Plant Extracts against Sclerotinia sclerotiorum (Lib.) de Bary Causing Stem Rot of Mustard

Sclerotinia stem rot (SSR) is one of the most destructive disease mustard which affects quality and quantity crop resulting in severe yield losses. The present study was conducted to evaluate bio-efficacy different Trichoderma spp. plant extracts against sclerotiorum under laboratory conditions. All tested showed a significant effect on growth inhibition test fungus over control. Among spp., maximum (73.33%) observed with T. viride followed by harzianum (67.77%). While as least efficacy found atroviride (38.37%) pathogen. Of all, Allium sativum proved be potent at all three concentrations (5, 10, 15%), thereby registering 59.26, 67.41, 100.0% Azadirachta indica Lantana camara, respectively. However, Argemone maxicana effective this study.
