The Argentine National Service of Health and Food Quality (Senasa) ordered the suspension of the herbicide, Wenko NT (2,4-D), from the National Register of Plant Therapeutics, as well as its certificates of use and marketing, after confirming that the product does not comply with the standards for registration.
AGM ARGENTINA SA was, therefore, granted a period of 180 days to restore the status of its product. If the product is not re-registered within this period, its registration will be subsequently cancelled.
As part of Senesa’s standard controlled testing, a sample of Wenko NT was collected and laboratory results highlighted an inconsistency in the concentration of active principle declared by the firm, so the agency decided to begin the suspension process.
According to AGM ARGENTINA, Wenko NT is a herbicide containing the active ingredient 2,4-D in its acid form, formulated as microemulsion. It is also based on oil, water and surfactants that form a single emulsion, composed of very fine drops (0.01 to 0.05 μm in diameter).
The product’s characteristics include high-level herbicidal power, low volatility, and low phytotoxicity. It is a systemic, selective and post-emergent herbicide that control broadleaf weeds in various crops, grazing fields and uncultivated areas.
