Bravo Weather Stik is a fungicide formulated as a suspension concentrate (SC) containing 54.0% Chlorothalonil. It is used for the control of various plant diseases across a wide range of crops, including asparagus, beans (snap and dry), blueberries, brassicas, and carrots. The product is applied via ground, air, or chemigation. It is designed to be used in integrated pest management (IPM) programs. When applying, ensure thorough coverage. Note that the product can be toxic to aquatic invertebrates and wildlife; avoid direct application to water or areas where surface water is present. For application via irrigation systems, specific hardware like check valves and pressure switches are required to prevent back-siphoning. Users must follow specific PPE requirements, including long-sleeved shirts, long pants, chemical-resistant gloves, and shoes plus socks. A dust/mist filtering respirator is required if using high-pressure, hand-wound sprayers.
