Astakar 500WP

Technical Overview of Astakar 500WP Herbicide

Effective weed control in fodder beet crops requires precise selectivity to ensure crop safety. Astakar 500WP, manufactured by Yangzhou Pioneer Chemical Co., Ltd., utilizes triflusulfuron-methyl as its active ingredient. This chemical compound targets the acetolactate synthase (ALS) enzyme in susceptible weed species, effectively arresting plant growth and leading to necrosis, while leaving the fodder beet crop unaffected due to its specific metabolic resistance mechanism.

Technical Specifications and Application Logic

The formulation as a wettable powder (500 g/kg) is designed for optimal solubility and consistent active ingredient distribution within the spray tank. As a systemic herbicide, Astakar is absorbed primarily through the foliage, translocating through the vascular system to reach the meristematic tissues of target weeds, which is crucial for achieving deep-rooted control.

• Selectivity and Mechanism: The precise molecular configuration of triflusulfuron-methyl ensures that target weeds cannot metabolize the compound, whereas the fodder beet crop rapidly breaks it down.
• Post-emergence Strategy: As a selective post-emergence herbicide, it is most effective when applied at the early growth stages of weeds (cotyledon to 4-leaf stage).
• Application Parameters: The dosage range of 30–60 g/ha allows for precise adjustment based on weed density. With a capacity for up to 3 applications per season, it offers the flexibility needed for integrated pest management systems.

Supported by Astarta-Kyiv, Astakar 500WP (Hazard Class 3) provides a reliable solution for weed management in intensive agricultural settings. By neutralizing competition at critical growth stages, it ensures the fodder beet crop maximizes its yield potential. Adherence to the application rates and optimal timing is essential to avoid crop stress and achieve maximum efficacy across the field.
