Grantohs

Mechanism of Action: The Auxin Effect

"Grantox" utilizes MCPA, a classic synthetic auxin, to target broad-leaved weeds. Its technical advantage lies in systemic translocation: once the aqueous solution is absorbed by leaves, the active ingredient moves through the plant's phloem and xylem, accumulating in the meristematic tissues (growing points). This causes an uncontrolled, abnormal growth response, leading to the metabolic collapse of the weed.

Why Selectivity Matters

The product is specifically designed for selective weed control in grasses and small grains. Its biochemical logic is rooted in the plant's metabolism: cereals and pasture grasses possess enzymes capable of rapidly detoxifying phenoxy-type compounds, whereas susceptible species like wild mustard, sow thistle, or cleavers lack this capability. This ensures that the crop continues to grow safely while the target weeds are eliminated.

Operational Guidelines

• Formulation: Water-soluble concentrate, designed for high-quality dispersion in spray tanks.
• Application Timing: Post-emergence, targeting active weed growth phases to maximize systemic absorption.
• Dosage and Efficiency: With application rates between 0.7 and 3 L/ha, the herbicide offers flexibility to address varying infestation pressures without excessive chemical load.
• Safety and Standards: Classified as toxicity class 3; limited to a single application per season to protect crop health and soil balance.

Whether applied to barley, flax, alfalfa, or pasture grasses like meadow fescue, the product's performance is driven by its ability to neutralize invasive species from the root up. The manufacturing standards maintained by Nufarm GmbH & Co. (Austria) and Jiangsu Good-Harvest (China) ensure consistent chemical composition, making it a reliable tool for professional field management.
