Mancozeb is widely used as a broad-spectrum fungicide in agriculture to protect crops from fungal diseases. It is effective against a variety of pathogens, including those causing blight, leaf spot, and downy mildew in fruits, vegetables, nuts, and field crops. Farmers apply it as a foliar spray or seed treatment to prevent infections and ensure healthy plant growth. Its multi-site mode of action makes it less likely for fungi to develop resistance, making it a reliable choice for disease management. Additionally, it is often used in integrated pest management programs to reduce the reliance on single-mode-of-action fungicides. Proper application and adherence to safety guidelines are essential to minimize environmental impact and ensure its effectiveness.
