Paecilomyces lilacinus is currently a biological control product that mainly acts on nematodes. It is an endoparasitic fungus and is an important natural enemy of some plant parasitic nematodes.
It can parasitize eggs and infect larvae and females , can significantly reduce the damage of root-knot nematodes, cyst nematodes, stem nematodes and other plant nematode diseases of various crops, and the parasitic rate of eggs of root-knot nematode incognita is as high as 60%-70%.
The control targets of Paecilomyces lilacinus are mainly root-knot nematodes and cyst nematodes on eggplant, ginger, cucumber, watermelon, soybean, tomato, tobacco and other crops.
The biological control of plant pathogenic nematodes by Paecilomyces lilacinus is a research hotspot at present.
It has been found that the organisms that can prevent nematode diseases include fungi that prey on nematodes, nematodes, planarians, nematodes, insects, mites, etc.; parasitic nematode viruses, native Animals, bacteria, etc., can also use plant extracts, and its control effect is also better.
The rich metabolites produced by the metabolism of P. lilacinus can not only help plants resist harmful organisms, but also directly serve as nutrients for crops to promote crop growth. The active substances produced in it are similar to plant auxins, which can promote growth under low concentration conditions. Crop growth, and many enzymes such as glucanase and silk protease can promote seed germination and seedling growth.
In addition to controlling nematodes, Paecilomyces lilacinus can also secrete endogenous hormones such as indole acetic acid, which has a good effect on promoting the growth of crop roots.
