Zlakodin, w.d.g., (Sulfosulfuron, 750 g/kg)

Mechanism of Action and Selectivity

«Zlagodin» is a specialized systemic herbicide based on sulfosulfuron (750 g/kg), a potent member of the sulfonylurea class. The chemical efficacy relies on the inhibition of the acetolactate synthase (ALS) enzyme. By blocking this enzyme, the herbicide disrupts the biosynthesis of essential amino acids, causing immediate growth cessation in the meristematic tissues of weeds. For winter wheat, the product provides selective control: the crop rapidly metabolizes the active ingredient into inactive compounds, whereas target weeds lack this detoxification mechanism and succumb to the systemic effect.

Control Spectrum and Formulation Technology

The formulation of water-dispersible granules ensures high physical stability of the tank mix and prevents dust issues during handling. As a product manufactured by Sunrise Chemicals Co. Ltd., Shanghai, it is engineered for precision targeting of resilient weed species:

• Grasses: Quackgrass (Agropyron repens), Wild oats (Avena fatua), Yellow foxtail (Setaria glauca), Silky bentgrass (Apera spica-venti).
• Broadleaves: Cleavers (Galium aparine), Scentless mayweed (Tripleurospermum inodorum).

The recommended application rate is 0.013–0.026 kg/ha. Designed as a post-emergence (insurance) herbicide, it demonstrates excellent translocation throughout the plant's vascular system, which is crucial for managing perennial species like quackgrass that regenerate from rhizomes.

Application Guidelines

Following a single application, «Zlagodin» provides long-lasting protection. Classified as a Hazard Class 3 chemical, it requires standard protective measures during handling and application. Given its systemic nature, the best results are achieved when weeds are in their active growth phase, facilitating rapid uptake and systemic movement of the herbicide throughout the weed's structure, ensuring total control without compromising the wheat crop's development.
