Abstract

Chemical nematicides have potential for risks and pollution to the environment and human health. Hence, this promoted the needs to use alternatives from certain medical plants. This research was designated to evaluate certain moringa plant part residues with their aqueous extracts and seed oil suspension for controlling root-knot nematode, M. incognita on field dry pea (Pisum sativum L.) under screen house conditions. On the basis of  mean of total percentages of nematode reduction for each parameter, it was found that dry root powder registered the highest mean of total percentages of reduction (81.6%) followed by those of mashed fresh leaves (80.8%),  seeds powder (79.5%) and dry leaves (76.4%). When using extracts of moringa residues, it was noticed that aqueous extract of seeds powder achieved the highest percentage nematode reduction (81.1%) followed by extract of dry leaves powder (80.8%), extract of dry root powder (80.5%). The least reduction (74.2%) was caused by seed oil suspension Number of galls was reduced while number of nodules was increased according to the tested materials. Consequently, the different treatments improved plant growth and yield parameters.
