Abstract
The plant parasitic nematodes infect the root tissues of the plant causing root galls that lead to reduced
water and mineral uptake in the plant root system. Nematophagous fungus are used as biocontrol for the nematodes.
Among those Nematoctonus are one of the species used as bioagent. Nematoctonus species produces an extensive
mycelium and capture many nematodes with hour glass shaped adhesive knobs on the hyphae. Nematodes become
attached to these adhesive knobs and the cuticle of nematode is penetrated by the infective hyphae. This isolate of
Nematoctonus robustus is characterized by hyaline mycelium, dikaryotic in nature containing genetically two
different nuclei in each cell, having distinct clamp connection. The fungus has better colonizing ability on natural
solid substrates like wheat straw and rice straw. It also show good ability to colonize on different cereal grains and
various other waste products like coconut coir and FYM etc. This species is one of the best used for mass production
and effective for control of plant parasitic nematodes.
