Samum Forte 374 RK

Technical Profile of Samum Forte 374 RK

Samum Forte 374 RK by TerraVita Ukraine is a high-tech diquat-based solution that serves as both a powerful contact herbicide and a highly efficient desiccant. With a concentration of 374 g/l of active ingredient, it stands as one of the most concentrated solutions for rapid crop management and weed control.

Molecular Mechanism of Action

The efficacy of Samum Forte relies on the disruption of photosynthesis in green plant tissues. Upon contact with the leaf surface, the diquat ion induces a rapid formation of free radicals, which immediately damages cell membranes and leads to swift desiccation. As a contact herbicide, it does not translocate within the plant's vascular system, ensuring local, intensive action without systemic risks to the root system if applied correctly.

Why the 374 RK Formulation Matters

• Rapid Contact Action: Unlike systemic agents, Samum Forte triggers visual signs of plant necrosis within hours. In pre-harvest desiccation, this speed is crucial for optimizing logistics and protecting yield quality.
• Broad Control Spectrum: The product effectively targets annual broadleaf weeds, desiccating their green mass and easing the harvesting process for crops like rapeseed, soybeans, and sunflowers.
• Rainfastness: This water-soluble concentrate is designed for excellent leaf adhesion. Within 30 minutes of application, it is resistant to rainfall, ensuring high performance even in unpredictable weather.

Practical Application Notes

Dosage requirements depend on the specific task: from 0.5–1.0 l/ha for post-emergence herbicidal use to 3.0 l/ha and above for complete desiccation. To achieve optimal results, fine-droplet spraying is recommended. This maximizes the contact surface area, which is essential for penetrating dense crop canopies such as sunflower or oilseed rape.

Classified as a category 2 hazard, the product demands strict adherence to safety protocols during handling. However, Samum Forte offers excellent environmental compatibility; it degrades rapidly in the soil, leaving no residual impact on future crops in the rotation, which allows for immediate planting post-harvest.
