Biochemistry Synthetic auxin (acting like indolylacetic acid). Mode of action Selective systemic herbicide, absorbed by the leaves and roots, with ready translocation throughout the plant via both the symplastic and apoplastic systems. Acts as an auxin-like growth regulator. Uses Control of annual and perennial broad-leaved weeds and brush species in cereals, maize, sorghum, sugar cane, asparagus, perennial seed grasses, turf, pastures, rangeland, and non-crop land. Used in combinations with many other herbicides. Dosage varies with specific use and ranges from 0.1 to 0.4 kg/ha for crop use, higher rates in pasture. Phytotoxicity Most legumes are sensitive. Formulation types GR; SL. Compatibility Precipitation of the free acid from water may occur if the dimethylammonium salt is combined with lime sulfur, heavy-metal salts, or strongly acidic materials.

Product analysis by i.r. spectrometry (AOAC Methods, 17th Ed., 969.07, 971.07; CIPAC Handbook, 1998, H, 127; M. A. Malina, Anal. Methods Pestic. Plant Growth Regul., 1973, 7, 545) or by hplc (AOAC Methods, 17th Ed., 984.07; CIPAC Handbook, 1988, D, 51). Residues in plants and soil determined by glc of a suitable ester (idem, ibid.; H. K. Suzuki et al., ibid., 1978, 10, 305). In drinking water, dicamba, its 5-hydroxy, and des-methoxy derivatives may be determined by conversion to methyl ester with diazomethane, then glc with ECD (AOAC Methods, 17th Ed., 992.32).

Animals In mammals, following oral administration, dicamba is rapidly eliminated in the urine, partly as a glycine conjugate. Plants The degradation rate in plants varies greatly with species. In wheat, the major metabolite is 5-hydroxy-2-methoxy-3,6-dichlorobenzoic acid, whilst 3,6-dichlorosalicylic acid is also a metabolite. Soil/Environment In soil, microbial degradation occurs, the principal metabolite being 3,6-dichlorosalicylic acid. Under conditions amenable to rapid metabolism, DT50 <14 d. Koc 2.
