An experiment was conducted in the laboratory of Department of Plant Pathology, SHUATS, Prayagraj, U.P. during 2019-2020 to observe the effect of 15 botanical extracts against Rhizoctonia solani by Poison Food Technique. Among the treatments Piper nigrum, Centella asiatica and Lawsonia inermis were found to be effective at different concentration (5%, 10%, 15%) with an inhibition percentage of 85.5%, 80% and 75.5% respectively as compared to control. Mycelial growth of Rhizoctonia solani was not inhibited by Aerva lanata, Ocimum sanctum and Biophytum sensitivium. Antagonistic effect of Metarhizium anisopliae against Rhizoctonia solani was evaluated in in-vitro condition by dual culture method and an inhibition of 60% was recorded against Rhizoctonia solani. A pot experiment was conducted in the shade net to evaluate the activity of Metarhizium anisopliae against Meloidogyne graminicola in rice seedlings. Root gall population was found to be reduced in treatment containing Metarhizium anisopliae + Meloidogyne graminicola and Metarhizium anisopliae + Rhizoctonia solani + Meloidogyne graminicola as compared to control pots with an inhibition percentage of 54.4% and 74.2% respectively.

Keywords: Botanical extracts, Metarhizium anisopliae, Meloidogyne graminicola, Rhizoctonia solani, Root gall
