Establishing a Pre-Emergent Shield: The Power of Treflan

"Treflan," manufactured by Gowan Comércio Internacional e Serviços, is a cornerstone of professional weed management. This soil-applied herbicide provides a robust defense system by creating a protective zone in the upper soil layers, neutralizing annual weeds at the exact moment of germination. It is a strategic choice for crops that require a head start without the pressure of competing vegetation.

Why Growers Prefer Treflan

Unlike post-emergence herbicides that fight weeds after they have already begun to draw nutrients from the crop, Treflan acts as a preventative measure. This is particularly vital for crops like onions, garlic, cilantro, and cabbage, which have delicate early development stages. Key strengths include:

• Selective Control: Effectively targets annual grasses and broadleaf weeds while maintaining high crop safety when applied at recommended rates.
• Formulation Quality: The emulsifiable concentrate ensures uniform distribution across the field, providing consistent, field-wide protection.
• Economic Value: By controlling weeds before they emerge, it minimizes the need for labor-intensive mechanical cultivation, preserving both soil structure and moisture.

Application and Operational Insight

The performance of Treflan is highly dependent on precision application. As a soil-incorporated herbicide, it must be worked into the soil immediately after spraying. Because trifluralin can be sensitive to volatilization, mechanical integration into the top 5–7 cm of soil is essential for success. This ensures the herbicide reaches the germination zone of the weeds.

Treflan is the optimal solution for growers looking to maximize yield potential by eliminating weed competition right from the beginning. While it requires strict adherence to soil preparation and incorporation protocols, the payoff is a clean field throughout the critical phases of crop establishment. For those managing complex cropping systems, including oilseed rape and various vegetable crops, Treflan remains a reliable tool for maintaining high standards of field sanitation.
