Katana, z.p., (Methyl triflusulfuron, 500 g/kg)

Mechanism of Action and Selectivity

The core of "Katana" is triflusulfuron-methyl at a concentration of 500 g/kg. This compound belongs to the sulfonylurea class and acts as a potent inhibitor of the acetolactate synthase (ALS) enzyme. For an agronomist, this translates to an immediate cessation of essential amino acid synthesis in weeds, leading to a halt in cell division just hours after application.

A critical technical feature of this herbicide is its high selectivity. Triflusulfuron-methyl is specifically engineered to protect sugar and fodder beet crops. The crop plant can rapidly metabolize the active ingredient, neutralizing its effect, while sensitive weed species perish quickly.

Why Water-Dispersible Granules Matter

"Katana" is formulated as water-dispersible granules. This form is chosen to ensure maximum stability in tank mixes. Unlike powders, these granules do not dust, do not clump, and ensure the creation of a highly homogeneous working solution. A uniform suspension ensures that at a dosage of 0.03–0.05 kg/ha, the active ingredient is spread evenly across the field, preventing local under-dosing in areas where weeds like lamb's quarters or amaranth might otherwise survive.

Application and Field Efficiency

The systemic mode of action allows the product to rapidly penetrate the leaf surface and translocate throughout the weed's vascular system. This compensates for any slight irregularities in spray coverage.

• Control Spectrum: Effectively suppresses a wide range of broad-leaved weeds, including common lamb's quarters, pigweed, field mustard, wild radish, shepherd's purse, and common chickweed.
• Flexibility: Allows up to 3 applications per season, enabling growers to fine-tune protection strategies based on weed germination flushes.
• Technology: Its post-emergence (foliar) application makes "Katana" an essential rescue tool, allowing for immediate action once weeds emerge.

Utilizing this solution from China Chemical Industrial and Research Co. Ltd provides a high-tech approach to weed management during critical development stages of fodder beet, ensuring clean crops without stressing the target plant.
