The fungal antagonists of nematodes consist of a great variety of organisms belonging to widely divergent orders and families of fungi. They include nematode trapping fungi, endozoic fungi, fungi which produce toxic metabolites and parasites of nematode eggs, cyst and females. Among these groups nematode egg and cyst parasites are considered as important group in reducing several sedentary endoparasitic nematodes. Because the oviposition nature of these nematodes (both in the egg masses and cysts) results in the total exposure of the eggs to fungal attack and once fungal invasion takes place the process is progressive. The discovery of fungill parasites on the eggs of plant parasitic nematode has been very recent. Several organisms have been reported to parasitize eggs and cyst of plant parasitic nematodes.
