Stemate 500, KS (etofumezate, 500 g/l)

Strategic Weed Control: The Chemistry of Ethofumesate

The core of the Stemat 500, SC (500 g/l) formulation is ethofumesate, a benzofuran derivative that serves as a potent inhibitor of plant growth processes. Unlike foliar herbicides, this product acts primarily as a soil-applied agent. Upon application, it creates a chemical barrier in the upper soil layer, penetrating the emerging seedlings and roots of weeds. This physiological disruption prevents cell division and interferes with the formation of the cuticle, essentially halting weed development before or shortly after germination.

Technical Specifications and Field Performance

Manufactured by DDE Farm AG (Triesen, Liechtenstein), Stemat 500 is engineered for high-selectivity applications in fodder and table beets. The suspension concentrate (SC) formulation ensures excellent stability in the spray tank and uniform deposition on the soil surface, which is critical for maximizing its soil residual activity. It is specifically designed to combat difficult species, including common lambsquarters, redroot pigweed, shepherd's purse, common chickweed, catchweed bedstraw, and purple deadnettle.

• Systemic Residual Action: Provides a prolonged protection window by remaining active in the soil profile.
• Operational Versatility: With a recommended application rate of 0.5–2 L/ha and the flexibility of up to 3 treatments, it allows for a highly tailored weed management program.
• Crop Safety: Being a selective herbicide, it effectively eliminates competition without compromising the development of beet crops.

To achieve optimal results, soil moisture is a key factor, as it facilitates the activation of the herbicide within the topsoil layer. As a pre-emergence tool, it acts as a foundational element in integrated pest management. Following Class 3 toxicity protocols ensures safe handling while maintaining the efficiency of this specialized herbicide in protecting delicate beet crops during their most vulnerable growth phases.
