Williams, VG (cloquaralid, 750 g/kg)

Mechanism of Action and Selectivity

The core of Williams, VG is clopyralid in a high concentration (750 g/kg). This is an auxin-type systemic herbicide that is rapidly absorbed by leaves and translocated throughout the plant, including the root system. The ability of the active ingredient to penetrate meristematic tissues makes it highly effective against hard-to-control perennial weeds, such as Canada thistle and common ragweed.

Advantages of Water-Dispersible Granules

The water-dispersible granule (WG) formulation is a technological standard ensuring the stability of the spray solution. Unlike powders, Williams, VG granules are dust-free, easy to dose, and dissolve quickly in water without leaving residues. This minimizes the risk of nozzle clogging and ensures uniform coverage of the leaf surface, which is critical for the systemic effect of the herbicide.

Agronomic Application Features

This herbicide belongs to the class of selective agents. Its selectivity allows for safe use on cereal crops (wheat, barley), corn, fodder beet, and rapeseed without suppressing the crops. Key technical nuances include:

• Application timing: The product is applied as a post-emergence herbicide. Maximum efficacy is achieved when treating actively growing weeds (2–6 leaf stage for annuals).
• Application rate: The optimal operating range is 0.1–0.3 kg/ha, depending on the weed density.
• Spectrum of control: It effectively suppresses a wide range of broad-leaved weeds: scentless mayweed, creeping thistle, cornflower, common vetch, and common ragweed.

The product is classified as Hazard Class 3, requiring standard safety precautions during handling. The limit of 1 application per season is designed to prevent the development of weed resistance.
