Biological Activity: Chlorsulfuron is an acetolactate synthase inhibitor and selective systemic herbicide. Chlorsulfuron blocks the synthesis of branched-chain amino acids (valine and isoleucine), thereby inhibiting protein synthesis, cell growth, and cell division. Chlorsulfuron blocks G1 and G2 phase cell cycle progression in plant root tip cells without directly interfering with mitosis or DNA synthesis. Chlorsulfuron completely inhibits germination of non-target terrestrial plants and is highly toxic to aquatic macrophytes. Chlorsulfuron has low toxicity to mammals, birds and bees, and moderate toxicity to fish and aquatic invertebrates. Chlorsulfuron can be used in studies related to herbicides, plant cell cycles and ecotoxicology[1][2][3].

Prosulfuron | Prosulfuron is a fluorinated sulfonylurea herbicide with a reported acute oral LD50 of 546 mg/kg in female rats. Prosulfuron acts by inhibiting acetolactate synthase (ALS) to block the biosynthesis of branched-chain amino acids (valine, leucine and isoleucine) in plants, thereby suppressing weed growth. Prosulfuron may disrupt the soil microbial community balance in alkaline soils with minimal chemical degradation. Prosulfuron has low toxicity to humans and mammals, and can be used for the research of broadleaf weed control in maize and sweet corn. | |||||||||||||||||||||
