3336F is a broad-spectrum systemic fungicide intended for professional use on turf and ornamental plants. The active ingredient is thiophanate-methyl (41.25%). It is used to prevent and control various diseases including anthracnose, leaf spots, rusts, smut, and various root diseases. It can be applied to turf (lawns, golf courses, athletic fields) and ornamentals (annuals, perennials, bedding plants, shrubs, and trees). Application methods include hand, mechanical, or motorized sprayer, as well as pressurized drenched systems (flood, sprinkler, or drip irrigation). When using irrigation systems, ensure the system is designed for chemical application and does not contaminate public water supplies. For turf, it can be applied as a foliar spray or through irrigation. Note that this product should not be mixed with highly alkaline materials like Bordeaux mixture or lime, as this may cause degradation. Always follow Worker Protection Standard (WPS) requirements for handling and application.
