SDDA Classifies Dicamba Products as Restricted Use Pesticides


PIERRE, S.D. – As of April 30, 2018, all pesticide products containing only dicamba, and having agricultural use labels, sold in South Dakota are classified as restricted use pesticides (RUPs). This includes over-the-counter herbicides that were previously sold to unlicensed applicators and producers. Since these products have been classified as RUPs by the State of South Dakota, but not by the federal government, they will not display the restricted use pesticide legend on the label. A list of 2018 registered products impacted by this new classification can be found on the South Dakota Department of Agriculture’s (SDDA) website,, by clicking on the “Dicamba Information” link under the “Happening Now” section.

Applicators will be required to be certified private or commercial applicators to purchase and apply these products. In addition to state certification, the SDDA encourages applicators to take a dicamba-specific training. An online training is available on the SDDA’s website. All applicators will be required to maintain application records for each application of these products and any other RUPs. The records of application must be kept for three years.

Three dicamba products, Xtendimax with Vapor Grip technology, Fexapan with Vapor Grip technology and Engenia, were classified as RUPs by the Environmental Protection Agency effective October of 2017. Separate regulations surround the sale and use of these products, including a requirement that applicators complete a dicamba-specific training.

Any questions about this change or the regulation of dicamba products can be directed to the SDDA at 605.773.4432.

SDDA Approves Dicamba Products in South Dakota

December 19, 2017

PIERRE, S.D. – The South Dakota Department of Agriculture (SDDA) has approved Engenia, Xtendimax with Vapor Grip technology and Fexapan herbicides for use in South Dakota for the 2018 growing season. These labels expire Dec. 20, 2018.

The SDDA will use the federal EPA stamped label for use in the state. Per the EPA label, these products are now restricted use products, meaning the applicator must be a certified private or commercial applicator to purchase and apply the products. All persons applying the products must also complete a dicamba-specific training and examination. Documentation of completion of the training and examination will be required to purchase these products.

“As a producer myself, I understand the time and energy that farmers put into their crop each season. What is important to note for everyone is that these new label restrictions will require more planning, for both growers and applicators, this year prior to the planting season, as well as during the application season,” said secretary of agriculture Mike Jaspers. “However, the way we all handle application on every field, every time will impact the future of these products and agriculture in South Dakota. It’s important that we take the time to plan ahead to make sure we are being good neighbors and good stewards of this technology.”

As with all products registered by the department, applicators are required to read and follow the label prior to and during application. Application of Engenia, Xtendimax and Fexapan must be completed between sunrise and sunset when wind speeds are from 3-10 mph at boom height. Applications can occur until the R1 growth stage of the soybean crop, also known as beginning bloom.

Applicators will be required to maintain records of each application; records are required to be completed at the end of each day of application. Tank mix information must be printed and stapled to the spray record to verify the applicator referenced the website no more than seven days prior to application. The labeled tank mix information and allowable nozzles are available on the manufactures’ websites.
