Solitare Herbicide is a selective weed control product designed for use in turf, including residential, commercial, institutional lawns, athletic fields, commercial sod farms, and golf courses. It contains two active ingredients: Sulfentrazone (18.75%) and Quizalofop-p-ethyl (56.25%). This herbicide is specifically formulated to control various weeds, including annual and perennial grasses, as well as certain broadleaf weeds and sedges, depending on the specific application and target. It is used as a granular formulation, which can be applied as a dry granule or mixed with water to create a liquid spray. The product is effective in both cool-season and warm-season grasses. When using the liquid application method, users must ensure proper mixing and dilution according to label instructions. Handling requires personal protective equipment (PPE), including long-sleeved shirts, long pants, gloves, and shoes plus covers. It is important to avoid contact with skin or clothing and to prevent runoff into water bodies. The label provides specific instructions for application rates based on the target weed and turf type, as well as precautions for weather and environmental safety to prevent damage to non-target plants and water contamination.
