Beauveria bassiana is a naturally occurring entomopathogenic fungus that acts as a biological control agent against a wide range of insect pests, including thrips. It infects pests through their cuticle, producing toxins that disrupt their physiology and ultimately kill them. Due to its targeted action, environmental safety, and minimal impact on beneficial organisms, B. bassiana offers an eco-friendly alternative to chemical pesticides. Its application has shown promising results in controlling thrips, which are notorious for damaging crops by feeding on plant sap and transmitting plant viruses. Using B. bassiana as a biocontrol agent helps reduce reliance on synthetic chemicals while providing effective pest management.
