South Dakota Dicamba Use on Soybeans


On October 13, 2017, USEPA issued revised labels for the three dicamba products that are labeled for use on genetically engineered crops, including soybeans: Engenia (BASF), XtendiMax (Monsanto) and FeXapan (DuPont).  IT IS ILLEGAL TO USE ANY OTHER DICAMBA PRODUCTS ON SOYBEANS.

USEPA made Engenia, XtendiMax and FeXapan Restricted Use Pesticides, which means that only certified applicators (private applicators and commercial applicators) can purchase these products and a record of sale must be kept by pesticide dealers who sell the products.

The new labels for these products require that all applicators of the product must be trained on the proper use of these products; this includes private and commercial applicators and operators. You must make and keep a record of the application, and proof of training must accompany the record of application.  

The South Dakota agriculture industry is working together to offer classroom training opportunities for private applicators (farmers), commercial applicators and operators to ensure all applicators have the opportunity to use these products properly in 2018, in accordance with the new label requirements. There are significant changes in the product labels that must be followed and the training will provide detailed explanations and examples of proper dicamba use. At this point, only classroom training is being offered to fulfill the training requirement in order to ensure a thorough understanding of the labels and provide interaction with the instructors.

This website provides a list of dates and locations where the training will be offered, free of charge to certified applicators and operators, and to anyone who is interested in learning more about the use dicamba herbicides. We will continue to update this website with additional meeting locations, so check back if you don't see one in your area at this time. We encourage growers who plant Xtend soybeans to attend the training, even if you do not plan to apply dicamba yourself; it is important that everyone in the stewardship chain understand the proper use of these products and effective weed management principles.
