Abstract It is estimated that 10% of global food production losses are because of plant pathogens. Among pathogens plant‐parasitic nematodes is a continues threat to global food security. Root knot nematodes (RKN), Meloidogyne spp. are the most economically important nematodes that infect almost every agricultural crop and ranked at first position in top 10 globally important plant parasitic nematodes. Several practices have been developed for RKN management including chemical, physical, plant resistance and biological control. In biocontrol methods different antagonistic fungi belonging to different taxonomic groups were reported for their nematicidal activity against RKN among which Pochonia chlamydosporia is the most studied and most utilized bio control fungus that is well known for its antagonistic activity against M. incognita. Recent advancement in omics approaches such as next generation sequencing, proteomics, metabolomics and transcriptomic enabled the scientist to study P. chlamydosporia and its antagonistic activity against M. incognita. Thus scientist from different part of the world reported many findings on P. chlamydosporia and its pathogenicity to RKN. Detail information regarding all aspects of P. chlamydosporia pathogenicity when grouped together enhances its understandings for the efficient utilization and further exploration of hidden useful information for the management of RKN. Though current literature provides the information about P. chlamydosporia in different context but collective analysis that cover all aspects in the light of advanced omics developments was not reported yet. Through this review article we summarized the available information of P. chlamydosporia and its role for the management of RKN with special analysis on the work carried out on omics technologies. A comprehensive overview of action mechanism and factors that affect the P. chlamydosporia pathogenicity were also discussed.
