Topaz is a broad-spectrum fungicide containing 41.8% Propiconazole. It is designed for the control of various plant, turf, and ornamental diseases. The product can be applied via ground application, aerial application, or through irrigation systems (chemigation). It is effective against diseases such as Brown Rot (Blossom Blight) in almonds and Anthracnose in certain crops. When applying, users should consider wind speed, temperature, and humidity to minimize drift. For ground applications, use a minimum of 50 gallons of water per acre for trees and 10 gallons per acre for other crops. For aerial applications, use 10 gallons of water per acre for trees and 2 gallons per acre for other crops. Note that this product should not be used in greenhouses or as a tree injection. Handling requires specific personal protective equipment (PPE), including chemical-resistant gloves (barrier laminate or viton), protective eyewear (goggles or face shield), long-sleeved shirts, long pants, and shoes plus socks. It contains petroleum distillates, which may cause aspiration pneumonia if swallowed. Always follow local regulations and the Worker Protection Standard (WPS) when applying.
