Dithane M-45 is a broad-spectrum protectant fungicide used to control various fungal diseases on certain vegetables and ornamentals. The active ingredients are Mancozeb (68%), Ethylene bisdithiocarbamate ion (CHNS) (16%), and Manganese (16%). It is designed to be applied as a spray to prevent disease before symptoms appear. It is primarily used outdoors on crops such as tomatoes, cucumbers, potatoes, grapes, and various ornamentals like roses and begonias. When applying, ensure thorough coverage of plant surfaces. Note that this product may stain concrete and masonry surfaces. Users must follow specific PPE requirements, including chemical-resistant gloves, long-sleeved shirts, pants, shoes, and socks, and must wash hands thoroughly after handling. It is important to avoid application during high wind conditions to prevent drift and to follow specific reentry intervals (REI) for treated areas.
