Abstract
Plant pathogenic nematodes, which are more than 4100 species, severely infect nearly all types of crops causing serious diseases .The efficacy of some aqueous extract for some plants, on eggplant plants, the effectiveness of wormwood (Artemisia herba- alba L.), mustard (Brassica juncea L.), pot marigold (Calendula officinalis L.), globe amaranth (Gomphrena globosa L.), and oleander (Nerium oleander L.) was compared to that of oxamyl, a common nematicide. Wormwood extract achieved the highest reduction (69.08%), which was followed by Oleander, Globe Amaranth, and Pot Marigold with reduction rates of 68.66, 63.02, and 57.39%, respectively. Mustard, on the other hand, showed the least amount of eggs per gram of root, resulting in a 64.53% reduction. Oleander achieved the greatest reduction in the amount of J2 in the soil (75%), followed by wormwood (73.33%) and pot marigold (68.66%). On the other hand, mustard had the least impact on the amount of J2 in the soil, resulting in a 43.33% drop.
