HistoryHerbicide reported by H. L. Palm et al. (Proc. 1989 Br. Crop Prot. Conf. - Weeds,1, 23). Introduced by E. I. du Pont de Nemours and Co. and first marketed in Europe in 1991.ManufacturersDu Pont


BiochemistryBranched chain amino acid synthesis (ALS or AHAS) inhibitor. Acts by inhibiting biosynthesis of the essential amino acids valine and isoleucine, hence stopping cell division and plant growth. Crop selectivity derives from rapid, selective metabolism by contraction of the sulfonylurea group and ring migration (L. Martinetti et al., Proc. Br. Crop Prot. Conf. - Pests Dis., 1995, 1, 405) and by hydroxylation on the pyrimidine ring, followed by glucose conjugation (M. K. Koeppe, IUPAC 5E-003 (1998); see Environmental Fate.Mode of actionSelective systemic herbicide, absorbed by the foliage and roots, with rapid translocation to the meristematic tissues.UsesRimsulfuron is a post-emergence sulfonylurea herbicide that effectively controls most annual and perennial grasses and several broad-leaved weeds in maize. Also used in tomatoes and potatoes. The target rate for most situations is 15 g a.i./ha. Rimsulfuron has a wide crop-safety margin under most conditions.Formulation typesWG.Selected tradenames:'Titus' (Europe, Africa, Mediterranean) (Du Pont)
