Effective Cereal Protection: The Mechanism of «Штефаране»

«Штефаране» (Stefanane) from DDE Farm AG (Liechtenstein) is a specialized systemic herbicide designed for the selective control of a wide range of broadleaf weeds in winter and spring cereals. The active ingredient, fluroxypyr, is an auxin-type compound that revolutionizes post-emergence crop protection strategies.

Technical Breakdown: How It Functions

The core advantage of «Штефаране» lies in fluroxypyr's ability to rapidly penetrate the leaf cuticle and travel into the meristematic tissues of the weed. Unlike contact-based agents, its systemic action ensures the complete eradication of both the above-ground biomass and the root systems of resilient weed species.

• Control of Persistent Species: Highly effective against cleavers (Galium aparine), field bindweed (Convolvulus arvensis), common chickweed (Stellaria media), and purple dead-nettle (Lamium purpureum).
• Selectivity: Due to its selective mode of action, the product is safe for cereal crops when applied according to the label, allowing treatment during the tillering phase without risk of phytotoxicity.
• Formulation: Supplied as an Emulsifiable Concentrate (EC), it provides excellent tank-mix stability and rapid systemic absorption even under challenging field conditions.

Field Application Guidelines

To ensure peak biological performance, apply at a rate of 0.15–0.3 L/ha. As «Штефаране» is classified as a Category 3 hazard, strict adherence to safety protocols is mandatory during tank mixing. Since only one application per season is permitted, timing is critical: target early weed growth stages when plants are most susceptible to systemic translocation. This product is an essential component in intensive wheat and barley production systems, ensuring weed-free fields during the critical yield-forming stages.
