CAS 100784-20-1: Halosulfuron-methyl
Description:Halosulfuron-methyl is a selective herbicide primarily used for controlling broadleaf weeds and certain sedges in various crops, particularly in rice and turf management. It belongs to the sulfonylurea class of herbicides, which function by inhibiting the enzyme acetolactate synthase (ALS), crucial for the synthesis of branched-chain amino acids in plants. This compound is characterized by its systemic action, allowing it to be absorbed by plant roots and foliage, leading to effective weed control. Halosulfuron-methyl is typically applied post-emergence and is known for its low toxicity to mammals, making it relatively safe for use in agricultural settings. Its solubility in water and moderate persistence in the environment necessitate careful management to minimize potential impacts on non-target species and ecosystems. Additionally, it is important to follow recommended application rates and timing to optimize efficacy while reducing the risk of resistance development in weed populations.
