Sirius

Japanese precision in rice crop protection

«Sirius», developed by «Nissan Chemical Corporation», represents a high-tech solution for rice growers facing the persistent challenge of Alisma plantago-aquatica (common water-plantain) infestation. As a global leader in agrochemical innovation, Nissan Chemical brings the rigorous standards of Japanese engineering to field-level crop protection. This selective systemic herbicide is specifically formulated to integrate into the metabolic processes of weeds while remaining perfectly safe for rice plants.

Technical efficiency and mechanism

The core of the product's performance is Pyrazosulfuron-ethyl, a member of the pyrazole family. By inhibiting the acetolactate synthase enzyme, the herbicide effectively halts cell division in weed growth points. Its systemic nature and root-absorption method make it particularly effective in the flooded environments typical of rice cultivation.

• Selective action: High efficacy against water-plantain without compromising the rice crop.
• Flexibility: A post-emergence herbicide that allows for precise timing to tackle weed pressure.
• Formulation: Water-dispersible granules, providing excellent solubility and coverage consistency across the paddy field.
• Operational efficiency: Low application rates (up to 0.5 L/ha) help optimize input costs while maintaining a high safety profile (Hazard Class 3).

With a short pre-harvest interval of just 1 day, «Sirius» offers immense flexibility in modern intensive rice farming. The requirement for only a single treatment per season simplifies agronomic management, allowing producers to effectively clear their fields during critical growth stages. When applied, the systemic movement ensures that the herbicide reaches the roots of the target weeds, effectively neutralizing them while allowing the rice to thrive without competition.
