This research discovered a new virus that can weaken harmful plant fungi that cause crop diseases. The virus works by disrupting the internal transport system of the fungi, making them less able to infect plants. This discovery is important for developing environmentally friendly ways to protect crops from fungal diseases. Key impacts on everyday life: • Could lead to reduced use of chemical fungicides in agriculture • May help protect important food crops from fungal diseases • Offers a natural, environmentally friendly approach to crop protection • Could help reduce crop losses and improve food security • May lead to lower food production costs for farmers
