Rimsulfuron
other name:N-[[(4,6-dimethoxy-2-pyrimidinyl)amino]carbonyl]-3-(ethylsulfonyl)-2-pyridinesulfonamide
CAS No.: [ 122931-48-0 ]
Molecular Formula: C14H17N5O7S2
Rimsulfuron is a herbicide, which affects sensitive weeds through inhibition of the plant enzyme acetolactate synthase (ALS), which then blocks the synthesis of essential, branched-chain amino acids. The first symptom of activity is in the meristematic tissues of sensitive species. Growth inhibition is followed by yellow and/or brown colouring and plant death. It is used post-emergence in maize (corn) under field conditions against a variety of annual and perennial grasses and weeds.
APPLICATIONS
Biochemistry
Branched 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. - Weeds, 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 action
Selective systemic herbicide, absorbed by the foliage and roots, with rapid translocation to the meristematic tissues.
Uses
Rimsulfuron 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/ha. Rimsulfuron has a wide crop-safety margin under most conditions.
