Proxan Ektiv 720 KE

Technological Edge in Soil-Applied Weed Control

The Proxan Ektiv 720 KE formula is powered by propisochlor, a selective active ingredient that, at a concentration of 720 g/l, provides a potent blocking effect. This new-generation chloroacetanilide operates at a systemic level, inhibiting the biosynthesis of proteins and nucleic acids in the meristematic tissues of germinating weeds. Through its systemic action, the herbicide is absorbed by the coleoptile and roots, making it a critical tool during the early development phase of crops.

The Advantage of the Emulsifiable Concentrate (EC) Form

Selecting the emulsifiable concentrate (EC) form for soil application is a deliberate technical choice. Unlike suspension concentrates, the EC formulation creates a more uniform barrier when interacting with soil moisture. This is vital for crops such as winter rape, soybeans, sunflowers, and corn, where the margin for safety between crop germination and weed elimination is extremely narrow.

Mechanism of Action and Application Rates

• Selectivity: The product is engineered so that crop plants possess the metabolic ability to break down the herbicide molecules, while susceptible weeds (primarily annual grasses) are eliminated before they emerge.
• Application: The optimal rate ranges from 2.0 to 3.0 l/ha. For maximum efficacy, high-quality soil preparation is essential; the field surface must be fine-crumbed and free of large clods to ensure the active ingredient anchors evenly in the topsoil layer.
• Systemic Action: As a pre-emergence soil-applied herbicide, Proxan Ektiv 720 KE establishes a "protective shield" that prevents competing grasses from depleting soil resources during early vegetative stages.

The use of the product is strictly limited to one application per season, aligning with Class 3 safety regulations and minimizing stress on the agroecosystem.
