Flazasulfuron (CAS 104040-78-0) is a selective systemic herbicide belonging to the sulfonylurea class, primarily utilized for pre- and post-emergence control of broad-leaved weeds, grasses, and sedges in turfgrass, vineyards, and citrus orchards. This 1-(4,6-dimethoxypyrimidin-2-yl)-3-(3-trifluoromethyl-2-pyridylsulfonyl)urea compound functions as a potent Acetolactate Synthase (ALS) inhibitor in SL-160 based formulations, blocking the biosynthesis of essential amino acids (valine and isoleucine) in target plants, leading to rapid growth cessation. To support industrial-scale requirements, we provide bulk supply with competitive factory pricing and ensure rigorous quality control through customized specifications alongside standard technical documentation, including MSDS, TDS, COA.

Product Description
Pyrisulfuron is a sulfonylurea herbicide with the chemical name 1-(4,6-dimethoxypyrimidine-2-yl)-3-(3-trifluoromethyl-2-pyridinesulfonyl)urea, and its trade names include Lufang, Nuanhoejing, etc. It blocks the synthesis of plant side-chain amino acids (leucine, isoleucine, valine) by inhibiting acetyllactate synthetase (ALS), causing weed growth to stall and death。 It is mainly used for warm-season lawns (such as dogtooth roots and zoysia grasses) to control broadleaf grasses, sedges and grasses, and has special effects on perennial sedge weeds such as fragrant aconite

FAQ - Technical & Supply Chain
-
Q:
What is the mode of action of Flazasulfuron (CAS 104040-78-0)?
A: It is a systemic ALS inhibitor (C13H12F3N5O5S) that is absorbed through both the foliage and roots of weeds, translocating to the meristematic tissues where it inhibits cell division, causing the weeds to stop growing within hours of application. -
Q:
Is Flazasulfuron safe for use on all turf types?
A: It is highly selective for warm-season turfgrasses (such as Zoysia and Bermuda grass) but can be injurious to cool-season grasses (like Fescue or Ryegrass), so formulation specificity and dosage control are critical.
