Granstar 75

The Benchmark in Selective Cereal Protection

Granstar 75 from the American corporation DuPont is not merely a herbicide; it is the industry-recognized standard for controlling broadleaf weeds in cereal crops. Since its introduction, the product has set a high bar for sulfonylureas, offering growers exceptional application flexibility and high-precision performance.

Why Granstar Remains the Professional's Choice

The efficacy of this product is rooted in tribenuron-methyl. This systemic active ingredient is rapidly absorbed by weed leaves, where it blocks the acetolactate synthase enzyme. Consequently, cell division halts within hours of application, with visible signs of weed necrosis appearing within a week. The model’s key advantage is its superior selectivity: wheat, rye, and barley possess the natural ability to metabolize the active ingredient, ensuring the crop remains completely safe.

Technological Application Insights

• Precision Control: Highly effective against aggressive field weeds such as field thistle (Cirsium arvense), common lambsquarters, and field bindweed.
• Application Flexibility: As a post-emergence foliar herbicide, it allows agronomists to wait until the majority of weeds have emerged, eliminating the risk of phytotoxicity-related crop loss.
• User-Friendly Formulation: The water-dispersible granule form ensures easy dissolution without dust or sediment buildup in spray tanks.
• Economic Efficiency: With a dosage rate of up to 25 grams per hectare, it serves as a cost-effective solution for large-scale operations, reducing logistics overhead.

It is important to note that the product is classified under Toxicity Class 3, requiring standard precautions when handling agrochemicals. The pre-harvest interval is only 1 day, underscoring its high environmental safety profile when used in accordance with labels. DuPont has engineered a tool that provides a margin for error in application timing and remains effective even in cooler weather conditions when many other herbicides become inactive.
