What is Bensulfuron-methyl?

Plain description, key identifiers and synonyms

Bensulfuron-methyl is the methyl ester of bensulfuron. An acetolactate synthase inhibitor, it is used as a herbicide for the control of a variety of both annual and perennial weeds in crops, particularly wheat and rice. It is not licensed for use within the UK. It has a role as an EC 2.2.1.6 (acetolactate synthase) inhibitor, a herbicide and an agrochemical.
