Plants synthesize secondary metabolites and some of them as well as their derivatives have antimicrobial activity such as alkaloids, flavonoids, isoflavonoids, tannins, coumarins, glucosides, terpenes and phenolic compounds. An attempt was made to evaluate the in vitro antifungal and biofumigant nature of ten different plants on suppression of mycelial growth of R. solani. Among these plant extracts at a concentration of , total inhibition of the pathogen was obtained on PDA incorporated with leaf extracts of cabbage and garlic creeper. The extracts of leaves of sweet potato () and radish () also gave significant suppression. Under in vitro evaluation of the biofumigant nature of plants, complete suppression of the pathogen was obtained on treatment with cabbage, cassava, garlic creeper and mustard. | Effect of biofumigation with plant extracts on mycelial growth and sclerotial germination of rhizoctonia solani causing collar rot and web blight of cowpea
