Cupola, WG, herbicide

Engineering the weed control: technical breakdown of Kupol herbicide

The success of potato field weed management rests on the precision of chemical intervention during the germination phase. 'Kupol', a herbicide by Rekord-Agro, utilizes Metribuzin (a triazine derivative) as its active engine. This compound acts as a systemic agent, specifically targeting the Photosystem II of weeds, effectively shutting down their metabolic processes.

Technical specifications and practical application

Designed as a pre-emergence, selective soil herbicide, 'Kupol' creates a protective layer in the topsoil that intercepts germinating weeds. The product's technical profile is optimized for field efficiency:

• Active Substance: Metribuzin provides consistent control over a wide range of annual dicotyledonous and grassy weeds.
• Formulation: Supplied as water-dispersible granules (WDG), ensuring excellent solubility, minimal dust during mixing, and long-term stability of the working solution.
• Systemic Selectivity: The herbicide is absorbed by the roots of emerging weeds, while the potato crop remains unaffected, making it an ideal tool for early-season weed control.
• Dosage and Handling: With recommended rates of 0.5–1.0 kg/ha, it allows for flexible adjustment depending on soil type and weed pressure.

By applying 'Kupol' before the potatoes emerge, growers can secure a 'clean start,' minimizing competition for light, water, and nutrients at a stage when the crop is most vulnerable. Classified under the 3rd hazard category, this herbicide requires standard safety protocols, but its high efficacy and concentrated form deliver excellent value-for-money, making it a staple solution for professional potato cultivation in Ukraine.
