Građ v.g., Herbicide

Technical Overview: Grad v.g. Herbicide Mechanism

Grad v.g., produced by Zhenjiang Agrin Company Ltd., is a targeted systemic herbicide designed for post-emergence control of broadleaf weeds in winter and spring wheat, as well as winter barley. The product’s efficacy is centered around its active ingredient, tribenuron-methyl (750 g/kg), which delivers precise, selective results.

Systemic Action and Molecular Impact

Unlike contact herbicides, Grad v.g. acts as a systemic agent. Upon application to the foliage, the active ingredient translocates through the vascular system to the meristematic tissues (growing points) of the weed. It inhibits the acetolactate synthase (ALS) enzyme, which is critical for the synthesis of essential amino acids (valine and isoleucine). This disruption halts cell division, leading to the rapid decay of sensitive weed species such as Canada thistle, common ragweed, field mustard, and shepherd's purse.

Key Formulation Advantages

• Water Dispersible Granules: The physical form ensures superior solubility in the spray tank, preventing nozzle clogging and ensuring a consistent, homogeneous concentration across the entire field.
• Selective Control: The herbicide is specifically formulated for cereal crops, which quickly metabolize the active ingredient, ensuring the crop remains unaffected while the target weeds are eliminated.
• Operational Flexibility: As a post-emergence herbicide, it allows for a flexible application schedule, enabling growers to target weeds during their most vulnerable growth stages.

Grad v.g. serves as a foundational component in integrated weed management for cereal production. By providing highly efficient control over persistent weeds like starwort, common chamomile, and field sow thistle, it protects the crop's yield potential during its critical early development phases.
