Granstar Pro 75

Why Granstar Pro 75 remains the gold standard for cereal crop protection

In the world of agrochemistry, sulfonylureas revolutionized weed management, and Granstar Pro 75 from DuPont stands as the benchmark for this technology. When fields are infested with stubborn perennials, this herbicide provides the selectivity that more aggressive alternatives often lack.

Precision targeting of tough weeds

The primary strength of this product lies in its ability to inhibit cell division in sensitive weeds. If your winter wheat or barley fields are struggling with Canada thistle, sow thistle, or field bindweed, Granstar Pro 75 works proactively. The active ingredient, tribenuron-methyl, is quickly absorbed by the leaves and stops weed growth within hours. While full desiccation takes 10–15 days, the competition for moisture and nutrients effectively ends immediately upon application.

Competitive advantages

• Superior Selectivity: The product is gentle on crops, minimizing stress even under fluctuating weather conditions.
• User-friendly formulation: The water-dispersible granules are easy to measure and dissolve rapidly, preventing sprayer nozzle clogs.
• Low dose efficiency: A application rate of up to 25g/ha significantly reduces logistical burdens for farmers.
• Short pre-harvest interval: With a waiting period of just 1 day before harvest, it allows for flexible late-season protection.

Application insights

As a systemic herbicide, Granstar Pro 75 performs best on actively growing weeds. The optimal application window is from the 2-3 leaf stage up to the flag leaf stage of the cereal crop. Keep in mind that for certain weed spectra, tank-mixing with partner products is recommended to ensure broad-spectrum control. The product is rated as Class 3 hazardous, so standard safety protocols must be followed during handling.

Who is this for? It is the ideal choice for growers who prioritize maintaining yield potential without risking crop growth suppression, opting for the proven reliability of DuPont over unverified generics.
