- Abstract
The biocidal activity of various isothiocyanates (ITCs) released by Brassica tissues is well-known for its potential to suppress a range of soil-borne pests and diseases. A study was carried out to evaluate the effect of incorporating fresh crucifer residue on root knot nematode, Meloidogyne hapla inoculum density, root knot disease development and celery yield. The ethanol extracts of cabbage, cauliflower, radish and Chinese cabbage leaves after harvest was applied to moist soil with high nematode population and covered with low density polyethylene sheets (50 micron thickness). After 15 days the sheet was removed and celery seedlings were planted. Observation on shoot length, root length, green leaf and stalk yield and nematode population were recorded. Biofumigation with sulphur containing cruciferous vegetable waste at the rate of 1kg/5 kg soil was found to reduce significantly the root knot nematode, M .hapla infecting celery and enhance plant growth and yield. Among the various sources evaluated radish leaf residue was the most effective resulting in 60.6 % reduction in nematode population in soil and 41.9% increase in celery green leaf and stalk yield compared to untreated control.
