Abstract
Plant parasitic nematodes cause significant reduction in yield and quality of many crops. Root-knot nematodes (Meloidogyne spp.) are widely distributed and of wide host range. Tomato is one of the most favorable hosts subjected to the attack of root knot nematode causing considerable losses in quality and quantity of yield. Chemical control of these nematodes using nematicides poses risks to the environment and human health. Therefore, the present study was conducted to exploit the nature’s biological potency to have effective biocontrol against root-knot nematodes, with no toxic residues. Isolation trials carried out on eggs, larvae, and adults females of root knot nematodes extracted from root and rhizosphere soil samples resulted in the isolation of several tens of fungal isolates. Screening of these isolates to verify their antagonistic activity against M javanica resulted in the selection of four fungal isolates exhibiting marked antagonistic activity.
