Viblock Plus ME

The Engineering of Oil Dispersion

The core advantage of Widblock Plus ME by Adama Agan Ltd. lies in its formulation: Oil Dispersion (OD). This is not merely a carrier; it is a sophisticated delivery system. The oil-based matrix allows the active ingredient, imazethapyr, to penetrate the tough, waxy cuticle of weeds much faster than standard emulsifiable concentrates. This rapid absorption is the decisive factor when treating hardened or drought-stressed weeds, where conventional products often fail to adhere or penetrate.

Systemic Action and Selectivity

Imazethapyr acts by inhibiting the enzyme acetolactate synthase (ALS), effectively halting the biosynthesis of essential amino acids (valine, leucine, and isoleucine). As a systemic herbicide, it translocates through the xylem and phloem, ensuring that the compound reaches the growing points and root systems of the target plants.

• Selective Weed Control: The formulation is engineered to provide specific physiological targeting, allowing it to control weeds effectively while maintaining crop safety for soybeans and sunflowers.
• Wide Spectrum of Targets: It excels at controlling a broad range of annual dicots and grasses, while simultaneously providing robust suppression of perennial grass species.
• Post-Emergence Flexibility: As a post-emergence herbicide, it allows for targeted intervention, enabling the farmer to spray exactly when the weed density reaches the economic threshold.

Technical Application Parameters

The application rate is set between 0.7 and 1.2 liters per hectare. A critical constraint is the limit of one application per season. This is essential for proper soil management and adhering to residual requirements in crop rotation cycles. As a Category 3 hazardous material with systemic mobility, achieving a uniform spray pattern across the canopy is vital. Utilizing precise nozzle technology ensures the oil dispersion is evenly distributed across the leaf surface, which is the primary site of action for this chemistry.
