As most know the EPA approved a new five-year registration for Engenia, Tavium and XtendiMax to be used in Xtend cotton and soybean. The new registration has some new labeled directions on application of these herbicides. In a series of articles this winter, we will try to highlight the major label changes.
One of the new labeled requirements for these three herbicides is the addition of a volatility reducing agent (VRA). Continue reading
All week we have discussed UTIA’s latest research on low-volatile dicamba formulations. We will end this series of blog posts with one of the first questions asked by TN soybean producers: Does adding glyphosate to low-volatile dicamba formulations increase its chances of moving outside the treated field via volatility? Continue reading
Tennessee soybean growers asked my colleague, Dr. Tom Mueller, and me to vet some of the directions on the XtendiMax and Engenia labels. In this third post we examine the ability of three pH modifiers approved on the Engenia label to raise spray tank pH. Continue reading
This is the second in a series of blogs on research that Dr. Tom Mueller and I did to examine some of the directions on the XtendiMax and Engenia labels. In the second test, we examined the effect on spray solution pH when AMS was added to Engenia or XtendiMax, with or without glyphosate. Continue reading
With the off-target dicamba movement in recent years, Tennessee soybean growers asked my colleague, Dr. Tom Mueller, and me to vet some of the directions on the XtendiMax and Engenia labels. The goal was to come up with information to help mitigate off-target dicamba. In a series of blog posts this week, we will share our most current findings. Continue reading
