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. 

Mode of action Broad-spectrum herbicide, absorbed rapidly by the leaves and roots, with translocation throughout the plant. 

Uses Control of annual and perennial grasses (especially Sorghum halepense) and broad-leaved weeds in non-crop land. Also used for selective weed control in Bermuda grass and certain other turf grasses; and in forestry to control woody tree species in pine trees. Applied either pre- or post-emergence. 

Phytotoxicity Not to be applied near desirable trees and plants.
