Tserkoshtef

Professional crop protection from Liechtenstein

Cerkostef is a systemic fungicide engineered by DDE Farm AG (Triesen, Liechtenstein), representing a precision-focused solution for modern plant health management. Distributed under the Steffes brand, this formulation leverages the synergy between two essential chemical classes—benzimidazoles (carbendazim) and triazoles (difenoconazole)—to tackle resistant fungal pathogens effectively.

Why Cerkostef stands out

• Systemic Efficacy: The active ingredients are rapidly absorbed, providing internal protection that shields new plant growth.
• Broad-Spectrum Control: Ideal for managing septoria, phoma, cercospora, powdery mildew, and downy mildew (peronospora) in corn and sorghum.
• Application Efficiency: With a dosage rate of up to 0.5 L/ha, it offers high economic value for large-scale production.

The product is formulated as a suspension concentrate, which simplifies tank mixing and ensures consistent stability in the field. Cerkostef is highly versatile, proving effective on key commercial crops including winter wheat, sunflowers, soybeans, and fodder beets. Its dual-action mechanism not only arrests existing infections but also establishes a durable chemical barrier against primary inoculums.

Regarding safety and regulation, Cerkostef is classified under hazard class 3, requiring standard PPE during handling and application. To ensure residue compliance, a 30-day pre-harvest interval (PHI) must be strictly observed. With a limit of two applications per season, it serves as a critical component in balanced crop protection programs, helping farmers maintain high-yielding, healthy fields regardless of variable pressure from environmental pathogens.
