Systemic weed control in fodder beet: technical analysis of Steffereb, WG

For high-yielding fodder beet production, the competitive pressure from broad-leaved weeds must be neutralized before it impacts crop development. Steffereb, WG, manufactured by DDE Farm AG (Liechtenstein), utilizes triflusulfuron-methyl (500 g/kg) as the active ingredient. This systemic herbicide functions by inhibiting the acetolactate synthase (ALS) enzyme, effectively halting amino acid synthesis and triggering rapid growth cessation in targeted weed species.

Technical Specifications and Formulation

• WG Formulation: The water-dispersible granule technology ensures rapid dissolution and high stability within the spray tank. This prevents sedimentation and nozzle clogging, which is essential for ensuring uniform application density across the field.
• Selectivity: Engineered specifically for fodder beet, Steffereb acts as a post-emergence herbicide. It allows for safe application at the 2–4 leaf stage of the crop, providing excellent weed control without inducing phytotoxic stress to the beets.
• Systemic Movement: Unlike contact-only herbicides, Steffereb is absorbed by foliage and translocated through the xylem and phloem to the weed's growing points. This ensures full elimination of tough weeds such as Chenopodium album (fat-hen), Amaranthus retroflexus (redroot pigweed), and Galium aparine (cleavers).

Application Strategy and Efficiency

The dosage ranges from 0.03 to 0.06 kg/ha. A key benefit of Steffereb is the allowance of up to 3 applications per season, which supports a split-application strategy. This approach is highly effective in managing multiple weed flushes throughout the growing season, keeping the weed pressure consistently low during the crop’s most sensitive growth phase. The препарат (herbicide) demonstrates high efficiency against shepherd's purse and purple dead-nettle when applied to young, actively growing weeds.

By prioritizing systemic efficacy and selectivity, Steffereb, WG remains a cornerstone for European-standard integrated crop protection, as defined by DDE Farm AG’s precision formulation standards.
