Paecilomyces lilacinus can parasitize on nematode eggs, Paecilomyces lilacinus can inhibit the chemotaxis of soybean 2 instar nematodes to soybean roots, and its fermentation broth has a good inhibitory effect on soybean 2 instar nematodes effect.
Paecilomyces lilacinus can secrete chitinase and serine protease, thereby degrading the chitin and protein components of the nematode epidermis, which is conducive to invading and destroying cell components.
At the same time, the study found that chitinase is helpful for the hatching of root-knot nematode eggs, the higher the concentration, the higher the hatching rate, and it has a toxic and killing effect on root-knot nematode larvae; it can also be endogenous in plants and produce effectors to other The fungi produce antagonistic effects; they can also colonize the rhizosphere of plants, produce secondary metabolites, and have inhibitory effects on fungi and nematodes.
