This research explores viruses that infect fungi (mycoviruses) and their potential use in controlling harmful fungal diseases that affect crops. Scientists have discovered that some of these viruses can weaken fungi that damage plants, offering a natural alternative to chemical pesticides. Impact on everyday life: – Could help protect food crops from fungal diseases without using harmful chemicals – May lead to more sustainable and environmentally friendly farming practices – Could reduce crop losses and lower food costs – Offers potential solutions for protecting forests and ornamental plants from fungal diseases – Could improve food security by providing new tools to fight plant diseases
