Abstract: Six treatments with organic amendments like neem oil, mustard oil cake, til oil cake, garlic extract and a chemical Furadan-3G including control were tested against root-knot on two local varieties of groundnut caused by Meloidogyne javanica. Treatment with Furadan-3G as side-dressing after 7 and 14 days of inoculation gave the best response in plant growth characters including nodulation correspondingly with the lowest number of galls, adult females and different juvenile stages of the nematode within the treated plants. Neem oil gave better effect with the reduction of galls and nematode population like that of Furadan-3G. Garlic bulb extract showed comparatively higher response in promoting plant growth and suppressing the nematode. Good effects were observed with the oil cakes of mustard and til.
