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 it has high total phenolic content of 280mg/100g. C.procera exhibited minimum inhibition percentage of 79.68. It has also least TPC of 75mg/100g.
