Product Introduction

Halosulfuron-methyl is a selective, systemic, foliar-applied sulfonylurea herbicide. It is mainly used in crop fields such as corn, rice, sugarcane, sorghum, lawns, and orchards, specifically for the highly effective control of sedge weeds. It exhibits particularly strong activity against perennial sedges such as nutgrass (Cyperus rotundus), Eleocharis yokoscensis, Cyperus serotinus, and Cyperus iria.

The herbicide can be absorbed through the leaves or roots of weeds and translocated to the growing points, inhibiting acetolactate synthase (ALS enzyme) and blocking branched-chain amino acid synthesis, ultimately leading to weed wilting and death.
