Revus Top is a broad-spectrum fungicide formulated as a suspension concentrate (SC). It contains two active ingredients: Mandipropamid (21.9%) and Difenoconazole (21.9%). This product provides preventative, systemic, and curative control for various plant diseases, including leaf spots, powdery mildews, and downy mildews. It is designed for use on a variety of crops such as cucurbits, brassicas, tomatoes, potatoes, cereals, and more. The product can be applied via ground application, aerial application, or through irrigation systems (chemigation). When applying, ensure thorough coverage is achieved. For ground applications, a minimum of 10 gallons of water per acre is required unless otherwise specified. Note that this product is Group 3 and Group 40 fungicides, meaning resistance management is critical; avoid using other fungicides from these groups in the same season. Handling requires specific PPE, including long-sleeved shirts, long pants, shoes plus socks, and chemical-resistant gloves made of waterproof materials like polyvinyl chloride, nitrile rubber, or butyl rubber. Always wash hands thoroughly after handling and before eating, drinking, or using tobacco. This product is toxic to fish, mammals, and aquatic invertebrates; avoid application near water or areas where runoff may occur.
