For producers that intend to use Xtend cotton or soybean in 2020, you will need to have an additional dicamba-specific certification to apply dicamba-containing products labeled for use in these crops. This certification must be renewed annually. Certification from last year is no longer effective.
At this time, the recommended way to get that certification is to complete on-line training provided by certain companies. Plan to set aside about 45-60 minutes to complete the training. Several online training options are listed below.
Paraquat-containing products (Gramoxone SL 2.0, others) will also require additional certification for all handlers and applicators. That training can be completed on-line at the link below.
