Abstract

Eight chopped fresh leaf plants namely; cabbage, lantana, castor bean, radish, watercress,, peppermint, camphor and datura were mixed with soil pots at two doses of 1 and 2 % of soil weight for controlling root-knot nematode, Meloidogyne javanica infecting tomato plants under greenhouse condition. Results revealed that all tested chopped leaf plants at both doses were effective in reducing nematode parameters compared to plants treated with nematode alone. Moreover, results confirmed that there are no significant differences between different chopped leaf plants with both doses in reducing nematode parameters. Cabbage and camphor chopped leaves at 2% significantly increased root fresh weight by 100%. Shoot fresh and dry weights were significantly increased with all tested chopped leaves at both doses except radish, watercress and peppermint chopped leaves. The activities of antioxidant enzymes i.e. phenoloxidase, peroxidase and catalase also showed high significant enhancement with all treatments at both doses compared with plants treated with nematode alone. The highest significant increase in antioxidant enzymes was obtained with cabbage and camphor chopped fresh leaves at 2%.
