Abstract
This invention belongs to the field of microbial extract technology, and discloses a strain of *Primatellella salina*, a microbial preparation, and its application in the prevention and control of root-knot nematode disease in *Salvia miltiorrhiza*. The *Primatellella salina* strain is named *Primatellella salina*. Priestia aryabhattai RH25-1, deposited on May 22, 2025, at the China General Microbiological Culture Collection Center (CGMCC), with accession number CGMCC NO.34628, exhibits excellent control effects against root-knot nematodes. It can be used as an active ingredient in microbial preparations for the control of plant root-knot nematodes, promoting the growth of *Salvia miltiorrhiza*, and enhancing plant stress resistance. This bacterium can also be used to prepare quinolinones. This application discloses a method for preparing quinolinone extracts from *Priscilla argentea*. This method is green and environmentally friendly, and can replace existing conventional chemical synthesis methods, meeting national green and environmental protection requirements.
