NORVEL, K.E.

Systemic weed control technology

"NORVEL, K.E." is a specialized selective post-emergence herbicide based on Quizalofop-P-ethyl, a member of the aryloxyphenoxypropionate chemical family. Designed to target problematic grass weeds, the product functions by translocating through the phloem to the meristematic tissues of both roots and shoots, ensuring complete elimination of weeds like couch grass (Elymus repens).

Mechanism of action: targeting plant lipids

The technical core of "NORVEL, K.E." lies in its inhibition of the acetyl-CoA carboxylase (ACCase) enzyme. By blocking this essential enzyme, the herbicide prevents the synthesis of fatty acids, effectively halting cell membrane production and arresting growth. This mechanism is crucial for high-efficacy results, as it permanently disables the reproductive systems of perennial grasses rather than merely desiccating the foliage.

Operational features and application protocol

• Selectivity and Versatility: The product is engineered for use in a diverse range of crops, including soybeans, sunflowers, oilseed rape, potatoes, and fodder beets. Its selective nature ensures grass weed control without causing phytotoxicity to the main crop.
• Application Efficiency: With a recommended dosage of 0.6–1.2 L/ha, it provides a consistent solution for controlling annual and perennial grasses. A single, well-timed application is typically sufficient to maintain a weed-free environment during the critical stages of crop development.
• Formulation Quality: Produced by Sunrise Chemicals Co. Ltd. (Shanghai, China), the emulsion concentrate formulation is optimized for water solubility and surface tension, allowing for uniform leaf coverage and rapid penetration of the plant cuticle.

By effectively removing competition for water and soil nutrients at the leaf-growth stage, "NORVEL, K.E." allows crops to reach their full yield potential. The systemic nature of the product ensures that even complex root structures are compromised, delivering lasting field protection.
