Several amendments to the XtendiMax, Engenia, and FeXapan labels have been issued by the EPA that will impact all purchases and applications of these products in 2018 and beyond.

Here's a summary from Kansas State University Extension on the agreements reached between the EPA and companies selling dicamba products registered for use on Xtend soybeans and cotton pertaining to label modifications and application requirements.

The states of Missouri and Tennessee have passed special restrictions to the use of dicamba, while Arkansas’ ban on dicamba sales still appears to remain as of Friday.

Tim Steunkel, marketing manager with TeeJet Technologies introduces the company's Turbo TeeJet induction nozzles, which are EPA approved for application of XtendiMax (Monsanto) and Engenia (BASF) on Dicamba tolerant crops. "The product allows for very coarse or ultracoarse droplets, which are often recommended for Dicamba applications, and offers drift control for both vapor and particle drift," Stuenkel says.

Arkansas has placed restrictions on the use of new dicamba herbicides, while Missouri introduced bills that will amend the approval process for herbicides and herbicide-resistant seed, as well the sale of herbicide-resistant seed if the corresponding herbicide has not garnered approval.

It's important to recognize that the costs associated with negligent applications of these products will not be limited to the crops damaged from off-target movement, says Iowa State University Extension.
