Scientists studied how Beauveria felina, a fungus used to control crop pests, grows when living alongside other fungi naturally found in plants. They discovered that instead of being inhibited by competitors, B. felina actually grew much faster when other fungi were present. In some cases, an inhibition zone formed between B. felina and one competitor fungus, suggesting they produce chemicals that affect each other’s growth. These findings suggest B. felina could be a good biocontrol agent, but researchers need to study longer-term effects before using it widely on farms.
