Astar 125 EC

Mechanism of Action and Selectivity

Astarg 125 EC is a high-performance systemic herbicide based on Quizalofop-P-ethyl (125 g/L). Unlike contact-based solutions, this product belongs to the aryloxyphenoxypropionate group, which works by inhibiting fatty acid synthesis in the meristematic tissues of target weeds. Due to its systemic nature, the active ingredient is rapidly absorbed through the leaf surface and translocated to the growing points, ensuring the total destruction of the root system, which is crucial for controlling perennial grasses.

Technical Formulation Advantages

The emulsifiable concentrate (EC) formulation is engineered to optimize adhesion to the waxy leaf cuticles. The high concentration of the active ingredient provides robust control over a wide spectrum of grass weeds, including quackgrass and foxtail, even at lower application rates. As a post-emergence herbicide, its efficiency is directly linked to the weed's development stage; the product achieves maximum impact when weeds are in the 2-4 leaf growth stage, where metabolic activity is at its peak.

Application on Fodder Beet

The selective nature of Astarg 125 EC allows for its use on fodder beet fields without causing phytotoxicity to the crop. As a systemic post-emergence herbicide, it is applied via foliar spraying on actively growing weeds regardless of the beet's development phase. This allows farmers to precisely target weed competition, preserving nutrients and moisture for the main crop throughout the critical stages of its development.

• Systemic Action: Ensures complete eradication of perennial weed rhizomes.
• Selectivity: Safe for broad-leaved crop protection.
• Stability: High-quality EC formulation provides excellent rainfastness shortly after application.

Given its categorization as a Class 2 hazard material, strict adherence to application protocols and safety measures is required. The efficacy of Astarg 125 EC remains consistent across various conditions, provided that environmental factors like temperature are within the recommended range for optimal systemic translocation.
