The biocidalactivity of various isothiocyanates (ITCs) released by Brassica tissuesis well-known for its potential to suppress a range of soil-borne pests anddiseases. A study was carried out to evaluate the effect of incorporating freshcrucifer residue on root knot nematode, Meloidogyne hapla inoculumdensity, root knot disease development and celery yield. The ethanol extractsof cabbage, cauliflower, radish and Chinese cabbage leaves after harvest wasapplied to moist soil with high nematode population and covered with lowdensity polyethylene sheets (50 micron thickness). After 15 days the sheet wasremoved and celery seedlings were planted. Observation on shoot length, rootlength, green leaf and stalk yield and nematode population were recorded.Biofumigation with sulphur containing cruciferous vegetable waste at the rateof 1kg/5 kg soil was found to reduce significantly the root knot nematode, M.hapla infecting celery and enhance plant growth and yield. Among thevarious sources evaluated radish leaf residue was the most effective resultingin 60.6 % reduction in nematode population in soil and 41.9% increase in celerygreen leaf and stalk yield compared to untreated control.
