Product Information

Flumetsulam is a well-defined, reliable, ALS inhibitor-based broadleaf weed herbicide suitable for use as a component of specific crops (legumes, cereals, corn, etc.). Always follow label instructions carefully when using, paying attention to the intended crop, growth stage, spraying conditions, environmental safety, and rotation constraints.

Basic Information

CAS Number: 98967-40-9

Molecular Formula: C₁₂H₉F₂N₅O₂S

Mechanism of Action: Inhibits acetolactate synthase (ALS) in plants, thereby blocking the synthesis of branched-chain amino acids, resulting in stunted weed growth and death.

Chemical Class: ALS inhibitor belonging to the triazolopyrimidine sulfonanilide class

Product Specifications

Common formulations are water-dispersible granules (WDG or WDG/WDG) or water-dispersible granules (WDG)/water-soluble granules (WG). For example, "Flumetsulam 800 WG/800 WDG" indicates a content of 800 g/kg.

Packaging sizes vary by country and brand (e.g., 500 g, 1 kg, etc.).

Registered as a "Glyphosate Group 2 Herbicide/HRAC Group 2"

Advantages and Limitations

Advantages

Effective against a variety of broadleaf weeds.

Demonstrates good selectivity in some crops (i.e., less damage to the main crop).

Can be used for post-crop control, providing flexibility.

Limitations/Risks

May be less effective against weeds resistant to ALS inhibitors.

Effectiveness may be reduced under high-stress conditions (low temperatures, high temperatures, alternating wet and dry conditions).

Environmental risks (especially water bodies) must be strictly controlled.

Not suitable for all crops/rotation systems, and subsequent planting may be limited.
