This research explored natural ways to control pest insects that damage commercially grown oyster mushrooms. Scientists tested two biological control agents – a bacteria and a beneficial nematode – finding that the bacterial treatment effectively reduced pest populations without harming mushroom growth. This provides mushroom farmers with an environmentally-friendly alternative to chemical pesticides. Impacts on everyday life: • Helps ensure sustainable production of healthy, pesticide-free mushrooms for consumers • Provides mushroom farmers with safer pest control options that protect worker health • Demonstrates effective alternatives to chemical pesticides in food production • Supports local and organic mushroom farming operations • Contributes to more environmentally-friendly agricultural practices
