Abstract

The tested nematicides and insecticides (Cadusafos, Furdan, Gupter, Mocap, Oxamyl, Malathion and Methomyl) 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 highest nematicidal effect against root galls formation, egg-masses and eggs per g root, recording 91.40, 91.28 and 96.34 reduction percentages in these parameters, respectively.While cadusafos gave the highest nematicidal effect in reducing number of juveniles in the soil by 94.39 %. On the other hand, 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 lowest root fresh weight was obtained by Malathion (16.89 g/ root), while the lowest root dry weight was obtained by Oxamyl and Cadusafos, which gave the same value (3.38 g/ root).
