Controlling Grass Weeds: Field Performance of Astarg 125, EC

When perennial grasses like quackgrass take over, yield losses in soybeans, sunflowers, or canola are inevitable. Astarg 125, EC, manufactured by Yangzhou Pioneer Chemical Co. Ltd., is a systemic herbicide designed to address this challenge by delivering high selectivity and powerful control over grass weeds while keeping the main crop safe.

The active ingredient, quizalofop-P-ethyl, works through a systemic mechanism. Once applied to the leaves, it is translocated throughout the plant to the roots. For farmers and operators, this is a significant advantage—it does not just burn the top growth; it kills the entire root system, preventing regrowth. This makes it particularly effective against persistent perennial grasses.

Operational Guidelines

The product is formulated as an emulsifiable concentrate, which ensures good miscibility in the spray tank. Being a post-emergence herbicide, it is best used when weeds are actively growing to maximize absorption.

• Effective Dosage: Depending on weed pressure and crop stage, application rates range from 0.4 to 1.2 liters per hectare.
• Selectivity: It is highly compatible with canola, soybeans, sunflowers, and fodder beet, allowing for broadcast application without crop stress.
• Application Timing: A single application per season, performed during the early growth stages of weeds, is generally sufficient for season-long control.

Working with Astarg 125, EC requires following standard safety protocols, as it falls under the 2nd hazard class. It is a reliable tool for professional field maintenance, where precision application leads to clean rows and healthier, higher-yielding crops. By stopping competition for water and nutrients early, this herbicide allows your crop to dominate the field immediately after treatment.
