- Introducing Pyrimisulfan
Pyrimisulfan is an ALS inhibitor in the sulfonanilide chemical class. It inhibits acetolatactate synthase, the enzyme common to the biosynthesis of the branch-chain amino acids. Research has shown, however, that pyrimisulfan may have activity against weeds that have developed resistance to other ALS-inhibiting herbicides such as sulfonylureas (SU’s).
