Management of Ashwagandha root rot disease with bioagents and fungicides

Abstract

The experiment was conducted to study the effect of bioagents and fungicides for management of ashwagandha root rot disease. Fusarium solani causing root rot disease is one of the serious pathogen because it attacks on root and deteriorate the quality of alkaloid. Among various treatments, minimum disease attack was observed in fungicide seed treatment with Mancozeb 63% + Carbendazim 12%. This combined fungicidal seed treatment also increases the germination (plant stand), fresh and dry root weight, shoot and root length and alkaloid content. In case of bio agents, Trichoderma viride was more efficient than Pseudomonas fluorescens in arresting the growth of pathogen, as compared to their individual applications over the un-treated control.
