An experiment was conducted under field condition, with a variety Pusa Purple Long. Before transplanting, the seedlings were given bare root dip treatments (for 30 minutes) in four systemic chemicals viz.,Carbosulfan (Marshal 25 EC), Imedacloprid (Confidor 17.8 SL), Dimethoate (Rogor 30 EC) and Oxy-dematon-methyl (Metasystox 25 EC). Each chemical was having two different concentrations (500 and 1000 ppm). Each treatment was replicated four times. Bare root dip treatments of transplanted seedlings with dimethoate, carbosulfan and oxy-dematon-methyl @ 1000 ppm (0.1%) were found very effective in reducing the nematode populations in the rhizosphere and root system of the plants. However, in comparison to control all the chemicals tested were found considerably effective, against the nematode at both the concentrations.
