STUDIES ON CERTAIN BIOLOGICAL CONTROL METHODS ON ROOT-KNOT NEMATODE INFECTING SOME VEGETABLE PLANTS

Abstract

Generally, plant parasitic nematodes are considered as one of the important pests. They cause many problems to vegetable, horticultural and field crops, and appear to be highly distributed in sandy soils, of which, root-knot nematode represents the most important and serious nematode pest, especially in Egypt. Nematicides, not only too expensive, but also have hazardous effects to environment and destructive influence to the Agro-ecosystem. Thus, biological control methods of nematodes is considered as the unilateral method of nematode population management, simultaneously preventing environment from pollution and saving ecosystem from being destroyed. The antagonistic fungi proved that they are , efficient in biological control agents of the plant parasitic nematodes.
