What farmers need to know about the new label for dicamba

There is a new label for dicamba applied to soybeans, and farmers need to be aware of those changes as the growing season approaches.

It is the first year of a new label for XtendiMax, Engenia, and Tavium, used in dicamba-tolerant soybeans and cotton. The registrations that were approved last fall by the EPA include new, or more application restrictions.

One weed scientist says that the modified labels means new limits of use.

University of Illinois Extension’s Aaron Hager states, “The labels of the initial products over the last three or four years have included essentially a similar listing of crops as you would find on the Clarity label. That is no longer the case. For example, XtendiMax now can no longer be applied to a cornfield.”

He says that another thing to watch out for is new restrictions to buffer zones and endangered species.

The “Endangered Species Protection Bulletin” on EPA’s website can sometimes change.

According to Hager, “One of the biggest potential consequences of this is that farmers or applicators in five or six counties may not be aware the new buffer requirements apply to them since they are now in a county with endangered species.”

That is because states can now add their own restrictions, in addition to federal ones. For example, five different counties are now on Illinois’s list from last year.
