| Abstract | ||
| The efficacy of some aqueous extract for some plants, wormwood (Artemisia herba- alba L.), mustard (Brassica juncea L.); Pot marigold (Calendula officinalis L.); globe amaranth (Gomphrena globosa L.) and oleander (Nerium oleander L.), compared with oxamyl as a standard nematicide was evaluated against M. incognita on eggplant plants. The highest reduction was obtained by Wormwood extract (69.08%), followed by Oleander, Globe amaranth, and Pot marigold with % of reduction of 68.66, 63.02 and 57.39%, respectively. On the other hand, Mustard exhibited the lowest effect number of eggs/ g root, which gave 64.53 % reduction. The highest reduction of the number of J2 in the soil was obtained by oleander (75%), followed by wormwood (73.33%) and pot marigold (68.66%). In contrary, mustard exhibited the lowest effect on number of J2 in the soil, which gave 43.33 % reduction. In general, Oleander and wormwood extract had the highest nematicidal effect against root galls formation, egg-masses and number of eggs per g root. The shoot fresh weight as compared with untreated inoculated control, which gave 34.82 g/ shoot. At rate of 100 mg/ml, pot marigold, globe amaranth, mustard, and oleander cloves extracts were significantly like non-inoculated control (56.84 g/ shoot). All the tested aqueous plant extracts and oxamyl significantly (p ≤ 0.05) increased the plant height as compared with untreated inoculated control, which resulted in a plant height (35.64) cm/ plant. | ||
