Bacillus subtilis or Bacillus amyloliquefaciens may antagonize some bacteria or fungi. It is generally recommended not to rashly add different strains to use together.

Should bacteria be awakened before the use of microbial pesticides?

As long as it is a pesticide product, there will be specifications, or at least the content of active ingredients. When the government approved the bio-pesticide license, it was presupposed that the product would be used directly in accordance with the packaging instructions.
