2,4-D Amine 4 is a Group 4 herbicide containing 47.3% Dimethylamine salt of 2,4-Dichlorophenoxyacetic acid as the active ingredient. It is designed to control a variety of annual and perennial broadleaf weeds in various agricultural settings, including corn, field crops, sweet corn, soybeans, asparagus, orchards (apples, pears, stone fruit, and nut), and certain grasses. The product can be applied via ground application or aerial application, though specific rates and methods vary by crop and target weed. When using for aerial applications, users must follow strict droplet size and wind speed guidelines to minimize drift. Handling requires significant personal protective equipment (PPE), including chemical-resistant gloves, protective eyewear, long-sleeved shirts, long pants, shoes/socks, and a chemical-resistant apron when mixing or loading. Users must be cautious of environmental hazards, particularly regarding groundwater contamination and aquatic toxicity. Always check local and state regulations, especially regarding drift management and specific state restrictions (e.g., California, Oregon, Washington).
