Gargin 500 FW, CS, herbicide

Weed control mechanism in Gargin 500 FW

The core efficacy of Gargin 500 FW lies in its active ingredient, Prometryn (500 g/L). This systemic soil-applied herbicide functions by inhibiting photosynthesis in weed cells. Formulated as a suspension concentrate, it ensures uniform distribution within the topsoil layer, forming a protective barrier. As weed seeds germinate, they absorb the active ingredient, leading to rapid sprout mortality before emergence.

Technical advantages of selective action

• Selectivity: Due to metabolic adaptations, crops such as carrots, soybeans, sunflowers, peas, coriander, and potatoes neutralize the active ingredient, while targeted weeds perish. This selectivity is vital for sensitive growth stages.
• Soil Residual Activity: The product serves as a pre-emergence barrier. A single application is sufficient to control the first flush of annual broadleaf and grass weeds, reducing field maintenance pressure during the early vegetative season.
• Stability: The Syngenta formulation provides excellent resistance to leaching and UV-induced degradation, making Gargin 500 FW a robust solution even under fluctuating weather conditions.

Practical application insights

For optimal performance, soil moisture is a key factor: Prometryn requires sufficient moisture to activate within the topsoil horizon. The application rate ranges from 2.0 to 3.0 L/ha (or higher), depending on soil texture: heavy, clay-rich soils necessitate higher doses to maintain the efficacy of the barrier, while lighter soils require the minimum. Usage is limited to one treatment per season, requiring precise timing—strictly before the crop emerges.
