Passat

Systemic Mode of Action: The Science Behind Passat

The efficacy of Passat relies on imazamox, an active ingredient within the imidazolinone class. Unlike contact-based herbicides, Passat is a systemic solution that enters the plant through the foliage and root system, translocating through the xylem and phloem directly to the meristematic growth points. By inhibiting the synthesis of essential amino acids—valine, leucine, and isoleucine—the product halts cell division in target weeds almost instantly.

Selectivity and Weed Control Spectrum

Designed for agricultural safety, Passat acts as a selective herbicide, allowing for safe application on soybeans, sunflower, and field peas. With a field dosage ranging from 0.5 to 1 liter per hectare, it targets a broad spectrum of critical broadleaf weeds, including:

• Common ragweed (Ambrosia artemisiifolia) and white goosefoot;
• Redroot pigweed and wild mustard;
• Shepherd's purse, common chickweed, and catchweed bedstraw.

Technological Precision

As a post-emergence herbicide, Passat is engineered for operational efficiency, requiring only one application per season. The water-soluble concentrate formulation ensures stability in the spray tank and optimal adhesion to plant surfaces, promoting maximum uptake. Manufactured by BASF Agro B.V. across high-tech facilities in France, Italy, Germany, and the USA, the product maintains a high standard of chemical purity and active ingredient consistency, which is vital for predictable field performance.
