Rootknot nematode Meloidogyne javanica egg masses and larvae were separatelyexposed to different concentrations of leaf extract of Euphorbiaheterophylla, Richardia bransiliensis and Scoparia dulcis contained inPetri dishes in the laboratory. Egg hatch inhibition and larval mortality wereobserved over a period of 96 hrs. Phytochemical analysis of each botanical wasstudied. A comparative study of the various extracts was carried out in thescreen house potted experiment. Perforated pots were filled with 4 kgsterilised sandy loam soil. Tomato seedling EX- Gombi was transplanted in eachpot and inoculated with 1000 second stage juveniles of M. javanica aweek later. 15, 20 and 25 mL of the crude extracts was applied weekly to eachpot. Distilled water serves as the control. The results of the study showedthat the extracts inhibited egg hatch, caused juvenile mortality in thelaboratory and reduced root knot nematodes infection on tomato in the screenhouse. S. dulcis at 25 ml showed better nematode control compared to R.brasiliensis and E. Heteropylla
