Efficacy of Phytoextracts and Bioagents Against Root Rot of Groundnut Induced by Sclerotium rolfsii

Efficacy of three medicinal plant extracts (neem leaf, cloves of garlic and cone of turmeric) and two bioagents viz., Trichoderma harzianum and Bacillus subtilis) were tested against the soil born pathogenic fungus, Sclerotium rolfsii to find out the inhibition of mycelial growth of the fungus. Inhibition of mycelial growth was maximum in Neem leaf extract and T. harzianum followed by cloves of garlic, cone of turmeric and B. subtilis. The results suggest that a combination of neem leaf extract and T. harzianum could be further exploited to develop an effective, and ecofriendly management package for this devastating pathogen.
