Abstract
Glucosinolate-containing Brassica spp. is known to release volatilic isothiocyanates (ITCs) which are toxic to
different pathogens. The chemistry involved in the biofumigation can be attributed to the action of myrosinases on the
glucosinolates (GLS) thereby releasing ITCs, thiocyanates, nitriles, oxalidine, dimethyl sulphide, methanethiol among
other compounds.The present study was taken up to evaluate different Brassica spp and onion for their biofumigation
effect against Rhizoctonia solani f. sp. sasakii in vitro. Among different brassica species, macerated mustard plant
parts are effective in inhibition of radial growth and sclerotial production of Rhizoctonia solani f. sp sasakii. In all
tested concentrations there was a positive association between increase of volumes and the rate of radial growth
suppression.
