Thifensulfuron-methyl（Cat No.:R069658）is a sulfonylurea herbicide used to control broadleaf weeds and some grasses in cereal crops such as wheat, barley, and oats. It inhibits acetolactate synthase (ALS), an essential enzyme in the biosynthesis of branched-chain amino acids, leading to halted cell division and plant death. Thifensulfuron-methyl is effective at low application rates, offering both pre- and post-emergence activity. Its high crop selectivity and favorable environmental profile, including low soil persistence and minimal toxicity to non-target organisms, make it suitable for integrated weed management in sustainable agriculture.
