Perun

Mechanism of action: Prometryn-based protection

"Perun" is a selective systemic soil-applied herbicide formulated as an emulsifiable concentrate, centered around the active ingredient prometryn. Its efficacy relies on inhibiting the photosynthetic process in weed species. The active substance is absorbed primarily through the shoots and root system during germination, blocking electron transport within the cells. This disruption leads to the cessation of metabolism and subsequent mortality of unwanted vegetation during the critical early growth stages.

Agrotechnical advantages of the formulation

Utilizing "Perun" as a pre-emergence herbicide creates a robust protective "barrier" in the topsoil layer. Due to its systemic nature, the product remains within the zone of active seed germination, ensuring crop cleanliness during the vulnerable initial phases of vegetation. Key specifications include:

• Action type: Systemic, soil-applied, selective.
• Control spectrum: Annual broadleaf and annual grass weeds.
• Application rate: 2–4 L/ha (depending on soil type and weed pressure).
• Maximum applications: 1 per season.

Crop application guidelines

The product exhibits high selectivity when applied to crops such as coriander, carrots, annual sunflowers, beans, peas, and potatoes. Applying "Perun" before seedling emergence reduces weed competition, providing the crop with a distinct growth advantage. Strict adherence to application regulations is essential, as the product is classified under Hazard Class 3. To achieve maximum efficacy, the soil must be well-prepared; the presence of large clods reduces coverage uniformity and the effectiveness of the herbicidal barrier.
