Abstract: 

Alternative measures to chemical control of plant parasitic nematodes were evaluated by using plant extracts and (or) plant residues of five species includingBunium persicum, Cuminum cyminum, Carum copticum, Foeniculum vulgare and Eugenia caryophyllata. Tomato seedlings were either dipped in water extracts of these plants at different concentrations before planting in soil infested with Meloidogyne javanica, or infested soil was amended with plant residues before the tomato seedlings were planted. At 60 and 90 days after planting, growth response of tomato, root infection by nematodes, and reproductive factor of nematode in pot cultures were evaluated. The results indicated that root dipping in the aqueous extract of C. cyminum was the most effective to decrease second stage juveniles and lower the reproductive factor. The extracts of F. vulgare and B. persicum were also effective to reduce the gall indices on tomato. Amending soil with plant residue of C.
cyminum (10% w/w) controlled M. javanica comparable to Caduzafos nematicide. Furthermore, amending soil with plant residues of C. copticum at 1, 5, and 10% w/w levels were effective against root knot nematode.
Plants treatment with Caduzafos nematicide and residues of C. cyminum (10% w/w) was indicated the best control. Improving soil with C. copticum residues shown a favorable effect against root knot nematode (M. javanica) at all tested rates (1%, 5%, 10% w/w).
