Dicamba Max 4 is a Group 4 herbicide used for weed control in various crops including corn, cotton, sorghum, soybean, small grains, pasture, hay, rangeland, and certain turf/grasses. The active ingredient is Dimethylamine salt of dicamba (3,6-dichloro-O-anisic acid) at 49.2%. It is designed to control a wide variety of annual, biennial, and perennial broadleaf weeds, as well as some woody weeds and vines. The product is available in dry and liquid formulations. When using liquid formulations, it can be applied with water or sprayable fluid fertilizer. Users must be cautious of sensitive crops, as dicamba can cause injury to many plants like beans, citrus, and grapes. Proper equipment cleaning is critical to prevent cross-contamination. Handling requires specific Personal Protective Equipment (PPE), including long-sleeved shirts, long pants, chemical-resistant gloves, and eye protection. Always follow the Worker Protection Standard (WPS) for agricultural use.
