In Vitro Studies on the Use of Some Plant Extracts as Bio control Agents against Fusarium Oxysporum Causing Rhizome Rot of Turmeric (Curcuma longa L.) andRole of Phenolics

摘要

Different plant extracts were studied in vitro for their efficiency of suppressing F.oxysporum causing rhizome rot of turmeric and role of Total Phenolic Content (TPC) of plant extracts in the antifungal activity, is also studied. The selected plant leaf extracts have shown significant antifungal activity (in vitro) against the mycelial growth of F.oxysporum causing rhizome rot of turmeric. Among them, Ocimum sanctum exhibited maximum antifungal activity of 99.45% inhibition over the pathogen and ithas high total phenolic content of280mg/100g. C.procera exhibited minimum inhibition percentage of 79.68. It has also least TPC of 75mg/100g.
