Dr. J.D. Green, UK Extension Weed Specialist, reports that two dicamba formulations, XtendiMax (Monsanto) and Engenia (BASF), received federal EPA approval in December for use with RoundupReady2Xtend soybean.
In addition to federal registration, a pesticide must also be registered and approved within a state before it can be sold. The XtendiMax product received state approval in early January for applications in Kentucky. The Engenia product is still pending state approval, but is anticipated in the near future.
