FAQ - Technical & Supply Chain
-
Q:
What is Flazasulfuron CAS 104040-78-0?
A: Flazasulfuron is a systemic sulfonylurea herbicide active identified by CAS 104040-78-0. It is also known by the development codes SL-160 and OK-1166 and trade names such as Shibagen and Katana. The active ingredient inhibits acetolactate synthase, also called ALS, which disrupts branched-chain amino acid production in susceptible weeds. -
Q:
Which weeds and crops is Flazasulfuron used for?
A: Flazasulfuron is used for selective pre-emergence and post-emergence control of grasses, broadleaf weeds, and sedges. It is especially active against Cyperus species such as purple nutsedge. Common use areas include warm-season turf, vines, sugarcane, citrus, olives, and non-crop or industrial sites where local registration allows. -
Q:
What technical and formulation grades are commonly available?
A: Technical Flazasulfuron is commonly supplied around 95% TC, while formulated products are often 25% WG or WDG. Typical properties include a white crystalline solid or powder, molecular formula C₁₃H₁₂F₃N₅O₅S, low vapor pressure, and pH-dependent water solubility. Confirm the exact specification needed for the intended formulation and destination market. -
Q:
How should Flazasulfuron be stored and handled?
A: Keep Flazasulfuron in tightly closed, secure containers in a cool, dry, ventilated storage area away from food, feed, heat, and incompatible materials. Avoid dust generation and use appropriate personal protective equipment. Because it is a pesticide active, follow destination-specific pesticide and dangerous-goods transport, disposal, and handling requirements.
