Among the major obstacles for the low productivity in food production, the plant pathogens especially plant parasitic nematode; Meloidogyne incognita occupies a significant position: however, individual fields may sustain losses of 50-100% from one or more pests. Their extensive host range, worldwide distribution and interaction (disease complexes) with bacteria, fungi and viruses make them potentially serious constraints and limiting factors to the crop production. Majority of the plant species, which account for the major world's food supply, is susceptible to attack from plant parasitic...
