The biofumigation is a biological method that aims the reduction of the number of pathogens, pests, and weed seeds in the soil. It is based on the use of plants with a high glucosinolate content, mainly cruciferous species. During the decomposition of these plants, glucosinolates are transformed in isothio- and thiocyanates. Latter substances are volatile and toxic to a number of soil organisms. The effect of the biofumigation on verticillium wilt, a soil-borne disease, was tested in a series of field and pot trials. The number of microsclerotia, organs of survival of verticillium wilt in the soil, was reduced between 19 and 74%. The factors influencing the efficacy of the biofumigation are discussed.
