Plant parasitic nematodes cause great economic losses to agricultural crops worldwide. They along, with their hosts, are not isolated in the ecological system, but are strongly influenced by antagonists, parasites and pathogens. Though pesticides appear to be the most economical and efficacious means of controlling plant pathogens, toxicological, environmental and sociological concerns have led to drastic reductions in the availability of efficient commercial nematicides. These restrictions have forced farmers to look for an integral system that makes use of other means of disease control. Species of spiral nematodes, Helicotylenchus and Scutellonema, were among the most abundant plant parasitic nematodes of the mulberry plant. Eco-friendly control of the parasitic nematodes could be achieved by means of endoparasitic fungi (like Hirsutella, Meria, Nematophthora and Nematoctonus), trapping fungi (like Arthrobotrys and Duddingtonia) or parasitic fungi (like Paeceilomyces lilacinus). During the course of this present work, Trichoderma Pers. Ex. Fr. was found to be one of the most effective fungi in controlling the eggs and J2 of Meloidogyne javanica. The present study outlines the comparative efficacy of five Trichoderma species (T. viride, T. harzianum, T. longibrachiatum, T. koningii and T. hamatum) against Helicotylenchus sp. and Scutellonema sp. The study also outlines the effect of Trichoderma viride Persoon on Scutellonema spp. and Helicotylenchus sp., effect of Trichoderma harzianum Raifae on Scutellonema sp. and Helicotylenchus sp., effect of Trichoderma longibrachiatum Rifai on Scutellonema sp. and Helicotylenchus sp., effect of Trichoderma koningii Oudeom on Scutellonema sp. and Helicotylenchus sp., and lastly effect of Trichoderma hamatum (Bonord) Bainier on Scutellonema sp. and Helicotylenchus sp.
