English Abstract

To evaluate the effect of neem cake (Azadirachta indica) and plant extracts of cabbage (Brassica oleracea var.

capitate), pepper (Capsicum annuum), garlic (Allium sativum), pomegranate (Punica granatum), castor (Riciuns communis),tanins(Thuja standishi) and bio-control agent Paecilomyces lilacinus.

An in vitro trial been conducted in laboratory of Kirkuk Directorate of Agriculture to compare the efficacy of three concentrations of plant extracts, bio-control agent and Oncol 5% G , as well as sterilized distilled water as a control in reducing the rate of eggs hatching and killing the second phase of the root knot nematode using Complete Randomized Design (CRD) .

Significant differences were found between the means of treatments and their concentrations for their effect on eggs hatching.

Garlic extract at concentration of 10% was the superior with lowest average of egg hatched 7.33/ 50 eggs, (14.66%) with no significant difference with standard nematicide Oncal 5% G ,neem cake, pomegranate, and castor extracts at 10% concentration.

Generally the number of dead 2nd star Juveniles is increased by concentration increasing.

Highest mortality rate was recorded in the direct exposure for higher concentration of garlic extract with an average of 42,333/50 dead juvenile/ 50 (84.666%) with no significant difference with higher concentration neem cake, pomegranate extract, castor extract and standard nematicide Oncal 5% G.
