Description

technical field

[0001] The invention relates to a microbial preparation, in particular to a Beauveria bassiana preparation for controlling pine caterpillars, in particular to a Beauveria bassiana preparation suitable for preventing and controlling pine caterpillars in northern arid areas, and its preparation method and application. Background technique

[0002] Pine forest is the main type of forest in our country, and it is the main content of natural forest protection projects. It plays an important role in the ecological security of our country, especially in the ecologically fragile areas in the north, where pine forest plays a huge role as a barrier.
