Effective control of Sclerotinia sclerotiorum, the causal pathogen of white and stem rot diseases of vegetable could be successfully achieved by using certain concentrations of furfural in growth medium or heavy infested soil. Culturing mycelia discs or sclerotia of S. sclerotiorum on PDA amended with 500, 1000, or 1500 ppm of furfural caused significant reduction in fungal growth and dry weight of sclerotia at 500 ppm with complete growth inhibitions when 1000 ppm was used on mycelial discs and 1500 ppm when sclerotia were cultured respectively. In soil, high levels of soil infestation with S. sclerotiorum (fungal growth suspension or sclerotia) were completely suppressed when 1500 ppm of furfural was incorporated in the soil 48 hr prior to transplanting eggplant seedlings. Disease incidence recorded on eggplant plants grown in untreated soil was 45%. These results confirmed the antifungal activity of furfural obtained with Rhizoctonia solani, Fusarium spp. and Pythium spp. along with the root knot nematode Meloidogyne javanica in previous studies.
