Description and Uses

Dicamba was introduced in the 1960s and is selective in cereals, corn (Zea mays), sugar cane (Saccharum spp.), asparagus (Asparagus officinalis), and turf for the pre- and post-emergence control of annual and perennial broadleaf weeds. Dicamba exhibits lowto- moderate persistence in most soils. See Table 10 for the nomenclature, chemical structure, and physical and chemical properties of dicamba.

Dicamba is mainly used as an herbicide to control weeds, dock, bracken, and brush. Dicamba is frequently applied with other herbicides, including atrazine, glyphosate, imazethapyr, ioxynil, and mecoprop.
