Proper soil management using rhizobacteria in combination with eco-friendly materials such as plant oils can considerably influence ecological processes through biota, resulting changes the structure and function of fauna. This work aimed to investigate effectiveness vitro besides under greenhouse field circumstances against root-knot nematode, Meloidogyne incognita. Commercial four seed plants including, Colocynth, (Citrullus colocynthis (L.), jojoba, (Simmondsia chinensis, Link) Schneid., moringa (Moringa oleifera Lam). marjoram oil (Origanum majorana L.) were tested on eggs J2 M. incognita egg immobility hatchability assay, larvicidal vivo conditions. Compared infected plants, significant effects (p ≤ 0.05) observed stock solutions recommended application rate (RC) versus vitro. Under environment, curative by significantly promoted fresh shoot, root, weight leaves count pepper than control. Rhizobacteria oxamyl resulted a elevated root shoot percent other compared plants. As well as, pots treated ranked next decreasing galls number masses, whereas O. showed lowest nematicidal effect. Field evaluation naturally tomato revealed that repeated mixtures exhibited better results declining numbers, density soil. These findings suggest possible mechanism manipulate plant-parasitic nematodes behaviour soils potentially reduce damage.
