Results of the use of various control methods (Chemical, Biological, Systemic Acquired Resistance (SAR) and Ethanol Extract of Chili Pepper ) individually or in combination showed improvement in all growth criteria of cucumber plants grown in soil infested with M. javanica eggs including length, dry and fresh weight of root and shoot system with chlorophyll content of leaves and strong reduction in infection criteria. The use of bio-health one week after Vydate as integrated control was found to be one of the most effective treatment compared to other treatments by improving all growth criteria of cucumber plants. On the other hand, the same treatment excelled in its effect on the other treatments where the highest reduction in infection criteria including number of galls, root gall severity, number of egg masses, number of nematode in root system, number of nematode in soil pot, number of eggs, final population density of nematode and reproduction rate of nematode in cucumber plants grown in infested soil as compared with control treatment (infested soil).The results also indicated that the less effective treatment was ethanol extract from chili pepper fruit in increasing cucumber growth criteria or reducing infection criteria.
