Abstract

Rapeseed-mustard is one of the major oilseed crops cultivated in India. Alternaria brassicae is the most destructive pathogen of oilseeds. The present study aims to evaluate the effect of bio-agents and elicitors on Alternaria brassicae of mustard in vitro using dual culture technique and poison food technique in completely randomized design (CRD). The study was conducted at the Department of Plant Pathology Laboratory, Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj. The results revealed that among bio-agents, Trichoderma viride + Pseudomonas fluorescens (87.70mm) recorded the maximum per cent inhibition of mycelial growth of Alternaria brassicae, followed by Trichoderma viride (82.60mm). Among elicitors, the maximum per cent inhibition of the pathogen was recorded  by salicylic acid at 150 ppm (75.33%), followed by salicylic acid at 100 ppm (58.69%).
