Monsanto upgrades dicamba prior to arrival of Xtend technology in Brazil
Sep. 14, 2018
By Leonardo Gottems, reporter for AgroPagesThe global leader in foliar products from Bayer says that Xtend technology, which adds resistance to the herbicide dicamba when applied to the Intacta 2 soybean, has minimized dicamba's volatility to very low level. According to John Hemminghaus, this characteristic of the active ingredient, indicated as causing a drift problem registered in the United States, was largely eliminated in the new formulation of the product.
Speaking exclusively to AgroPages, Hemminghaus explains that dicamba is an "effective weed control agent". The herbicide fights broad-leaved invasive plants that become resistant to glyphosate and other technologies, being a great novelty in the Intacta 2 Xtend Platform - the new generation of soybeans has a predicted release date of 2021 in Brazil.
Additionally, Monsanto/Bayer has been working with manufacturers of agrochemical spray nozzles to develop the most appropriate equipment. "The basic way to reduce particle drift is to select nozzles that produce droplets in the right way. Smaller particles can go further through the wind. By reducing the number of fine particles - by selecting the correct nozzle, we can reduce the distance that these particles travel. "
"In addition, we work with adjuvant manufacturers to develop drift reduction agents that are compatible with the nozzles we are recommending. With this we get an improved system, which goes beyond what the beak itself can provide," adds Hemminghaus.
He noted that the manufacturer's development research team has been "very proactive in developing a low volatility formula for dicamba. In addition, we have taken steps to limit the number of types of tank mixtures, such as ammonium sulfate, which can substantially increase volatility, in addition to certain glyphosate salts, such as dimethyl lauramine. In the United States we restrict the use of them. So, having a formula of low volatility, and being quite proactive with respect to the mixtures, really allowed us to minimize dicamba volatility. "
In the future, Hemminghaus told AgroPages that Monsanto/Bayer is already working on the next steps in developing a line of tolerant herbicide systems that bring new traits to be used in soybeans, corn and cotton. "The hope is that we can bring these new tools to producers who will have more flexibility in post-emergence solutions that allow them not only to spray a single herbicide, but to use multiple herbicides in a system that can effectively and sustainably control weeds ", he said .
