Meloidogyne incognita, a root-knot nematode that seriously damages agricultural plants, badly infects eggplant plants. In order to improve the active ingredient's distribution to the target nematode, farmers must apply chemical nematicides, either with or without adjuvants. The direct impact of nematicides and insecticides (Cadusafos, Furdan, Gupter, Mocap, Oxamyl, Malathion, and Methomyl) was examined in a recent study at the tested doses caused significant reduction in nematode root galls, egg-masses, eggs per 1g root and number of larvae / 250 g of soil compared to untreated inoculated control. Gupter had the most nematicidal impact on the development of root galls, egg-masses and eggs per g root, recording reduction percentages of 91.40, 91.28, and 96.34 in these variables. recording reduction percentages of 91.40, 91.28, and 96.34 in these variables. recording 91.40, 91.28 and 96.34 reduction percentages in these parameters, respectively.While cadusafos gave the highest nematicidal reduces the quantity of juveniles in the soil as a result by 94.39 %. As opposed to that,Malathion proved to be the lowest effective compound. Gupter gave the highest value in both fresh and dry root weight (19.06 g/ root) and (3.93 g/ root), respectively. While the smallest fresh root weight was obtained by Malathion (16.89 g/ root), while the smallest root dry weight was obtained by Oxamyl and Cadusafos, which gave the same value (3.38 g/ root).
