AGM Special Chemicals, a company of the German DVA Group, recently launched a new post-emergent systemic herbicide, Weizen NT, developed to control weeds in various crops, pastures and uncultivated areas. The product is composed of the active substance, 2,4-D, in its acid form, formulated in microemulsion. According to studies, the product has the lowest volatility in the market and zero phytotoxicity.
"The sales of this product was beyond expectations, and in addition to that, last week we received studies conducted by the National University of La Plata and the National University of Costa on the volatility and possible effects of phytotoxicity on neighboring crops," said Dardo Lizárraga, General Manager of DVA Argentina.
He explained that the product is based on oil, water and surfactants that form a single emulsion, composed of very fine drops, called micelles. In addition to the low volatilities and phytotoxicity, Weizen NT features an imperceptible smell, a wide compatibility of mixtures and a larger application window of up to seven days before planting.
“This allows us to reconnect with the government of the Argentine province of La Pampa, which, today, has restrictions on microemulsion applications, Lizárraga said. “We believe that we have enough technical information to support and start conversations that, in principle, allow us to understand from a technical point of view why the progress was made.” It might facilitate adoption of the product in this region.
