Abstract:

Root-knot nematode(Meloidogyne spp.)and cyst nematode(Heterodera spp.)are two kinds of plant-parasitic nematodes that are the most agriculturally damaging group of plant-parasitic nematodes worldwide. They infect roots the of the host plant, obtaining nutrition through giant cells or syncytia, affecting plant growth and development, and causing severe economic losses to crops. Trichoderma spp. is an important biocontrol resource in agricultural production. With the improvement of environmental protection awareness, Trichoderma spp. has recently attracted more and more attention as a biocontrol resource of plant-parasitic nematodes. Here we discussed the biocontrol mechanism, action mode, influencing factors, existing problems, and production application of Trichoderma against root-knot nematode and cyst nematode. Finally, we analyzed the issues of Trichoderma in biological control and provided insight into their application.

Key words: Meloidogyne spp., Heterodera spp., Trichoderma spp., biological control, interaction mechanism
