The approach, dubbed liquid culture fermentation, offers several benefits, including lower material costs and increased yields of certain forms of insect-killing fungi, including Isaria or Metarhizium, which can serve as biobased alternatives to synthetic pesticides.
For decades, biopesticide makers have grown such fun
