| Abstract | ||
| This study included laboratory evaluation of the effect of aqueous extract of Artemisia herba-alba leaves and aqueous extract of Peganum harmala seeds and fungal filtrates of A.niger and mixture of them against female and second stage juveniles of root knot nematode Meloidogyne javanica isolated from the roots of Solanum melongena. The results showed a difference in effectiveness of water extracts and fungal filtrate depending on concentration and duration of exposure. It was found that the concentration 10% for the extract of of Artemisia herba-alba leaves and aqueous extract of Peganum harmala seeds and mixture of them best in eliminating the largest number of female second stage juveniles of root knot nematode as ratios amounted to murder 100% after 24 hours while the least influence is the concentration 1% of aqueous extract of Artemisia herba-alba leaves amounting ratios murder for each of the female and second stage juveniles of root knot nematode 62.7% and 81%, respectively after 120 hours. When using fungal filtrates of A.niger it founded that the best concentration is 25% with percentage of killings 100% after 48 hours and the least influential is the concentration of 5%, with the percentage of murder for females 51.3% after 120 hours. When using a mixture of aqueous extract of Artemisia herba-alba leaves and aqueous extract of Peganum harmala seeds and fungal filtrates of A.niger it was found that he best concentration to the elimination of female and second stage juveniles of root knot nematode is 8% and 10%, with rates amounted to murder 100% after 24 hours either the least impact is the concentration 2%, with the percentage of murder for females 57.3 after 120 hours and the percentage of murder for of second stage juveniles of root knot nematode is100% after 96 hours. | ||
