Six different levels of abamectin 1.8 % (belongs to avermectins) viz., 50, 100, 200, 400, 800 and 1200 ppm were added to soil infected with Meloidogyne incognita, root-knot nematode on cow-pea plants under greenhouse conditions. A significant (p ≤ 0.05 and 0.01) reduction in nematode criteria was found compared to untreated check. Data showed a clear correlation between increasing of abamectin concentrations and the percentages nematode reduction in roots and soil. The higher concentrations (200, 400, 800 and 1200 ppm) showed 100 % nematode reduction. However, an adverse effect was observed on plant growth parameters. Plant growth criteria improved at 50 and 100 ppm.
