Effective Weed Control: The Potential of Prometryn

"Selefit c.s." is a classic soil-applied herbicide that has become a reliable tool for agronomists working with a wide range of industrial and vegetable crops. The product is based on prometryn, an active ingredient that has maintained its position in plant protection protocols for decades due to its predictability and selectivity.

Technical Profile and Mode of Action

The product is formulated as a suspension concentrate, which simplifies the preparation of the spray solution and ensures uniform distribution on the soil surface. As a systemic, selective herbicide, "Selefit c.s." acts preemptively: it is applied before crop emergence. By being absorbed through the shoots and roots of weeds, prometryn blocks photosynthesis, leading to the destruction of unwanted vegetation before it begins to compete with the main crop for water, light, and nutrients.

Application and Reputation

The manufacturer, China National Chemical Construction Ningbo Import and Export Co., has prioritized formulation stability. Agronomists choose this product for the protection of carrots, potatoes, coriander, as well as soybeans, sunflowers, and peas. The herbicide primarily targets annual broadleaf and certain annual grass weeds.

• The application rate is 2–4 L/ha, depending on soil type and weed pressure.
• The product requires a single application, making it an economically viable solution for intensive farming practices.
• Classified under hazard class 3, requiring standard safety measures during handling.

"Selefit c.s." has established itself as a "foundation" herbicide that minimizes risks at the start of the vegetation period, creating a "clean screen" for the development of crops.
