Abstract:

The diseases caused from root-knot nematode is the one damaging crops seriously but quite difficult to be controlled, and is becoming more and more serious with the development of facility agriculture in China. Conventional chemical control methods are not suitable for sustainable development of agriculture due to high toxicity and ecological damage. As a biological control fungus that can be stably parasitized in crops, endophytic fungi achieve stable, efficient and safe control of root-knot nematode diseases by inhibiting egg hatching, reducing the viability of J2 stage nematode larvae, inhibiting nematode invasion, delaying female development, reducing the number of laid eggs, and decreasing the number of root knots and egg masses in crop roots. In recent years, the action mechanism of endophytic fungi has received extensive attention and research, and significant progress has been earned. This paper reviews the research progress of biological control mechanism of endophytic fungi for root knot-nematode in recent years, summarizes four main mechanisms such as direct attack, resource competition, metabolite stress and defense activation of endophytic fungi, and discusses the existing issues, aiming to provide help for further development and application of plant endophytic fungi control technology.
