Stargesan 500

European standards for pre-emergence weed control

"Stargezan 500" is a well-established selective herbicide designed for professional crop protection. Developed by Fader Alliance Ltd. (UK) and manufactured in high-tech facilities across the Netherlands and Poland, this product brings European precision to farm management. As a systemic soil herbicide, it is specifically formulated to create a protective barrier that suppresses weed growth before they can compete with the primary crop for nutrients and moisture.

Technical efficiency and mode of action

The core of Stargezan 500 is prometryn (500 g/l) in a concentrated suspension form. This composition ensures stability during application and consistent coverage of the soil surface. By acting as a selective herbicide, it is absorbed through the root systems of germinating weeds, effectively halting their photosynthetic process. Because it is a pre-emergence treatment, it allows for a clean field start, which is critical for achieving optimal yield in various agricultural sectors.

Crop application range

Agroflex, the product applicant, recommends Stargezan 500 for a variety of crops sensitive to weed pressure during early development stages, including:

• Legumes: Soybeans, peas, and kidney beans;
• Technical crops: Sunflowers;
• Vegetables and herbs: Carrots and coriander.

The application rate is between 2 and 4 liters per hectare, depending on the specific soil type and weed infestation level. The herbicide is intended for a single application, ensuring that the crop establishes itself without the stress of early-stage weed competition.

Why choose Stargezan 500?

For modern farmers, Stargezan 500 offers a reliable way to manage weed outbreaks before they occur. Its systemic, soil-based action ensures long-term protection, reducing the need for mechanical inter-row cultivation. Given its European manufacturing standards and proven efficacy against annual broadleaf and grass weeds, it remains a preferred choice for producers looking for a predictable and powerful tool for their crop protection strategy.
