Systemic action technology: The core of Stef-Trel efficiency

Stef-Trel by Stefes is a selective systemic herbicide utilizing Clopyralid as its primary active ingredient. Unlike contact herbicides that merely burn the foliage, this formulation provides deep systemic control by translocating through the phloem directly to the growth points and the deep root systems of target weeds. This is the only way to effectively eliminate perennial, rhizomatous species like Cirsium arvense (field thistle).

Engineering and formulation benefits

• Selective herbicidal action: The product is precision-engineered for post-emergence application in winter wheat and fodder beet. It targets specific weed metabolic pathways, ensuring that the main crop remains unaffected and physiologically stable.
• Optimal delivery system: Formulated as a water-soluble concentrate, Stef-Trel ensures maximum solubility. This simplifies tank mixing and guarantees that spray nozzles remain clear, providing uniform coverage across the field.
• Targeting resilient weeds: The chemical profile is specifically optimized to eradicate stubborn broadleaf weeds, including Chenopodium album (fat-hen), Persicaria species (knotweed), and Centaurea cyanus (cornflower).

Operational field efficiency

With a maximum application rate of up to 0.5 L/ha, Stef-Trel offers a cost-effective solution for large-scale crop protection. Being a foliar-applied (insurance) herbicide, it gives farmers the ability to respond to weed pressure only after emergence, reducing unnecessary chemical input. A significant logistics advantage is the 1-day pre-harvest interval, which allows for safe treatment even late in the growing season without compromising safety standards or export regulations.
