Dicamba Cutoff Date Approaching
PIERRE, S.D. – The South Dakota Department of Agriculture (SDDA) reminds applicators that June 30 is the cutoff date for dicamba products.
The SDDA obtained Special Local Needs registration labels, also known as 24(c) labels, from the U.S. Environmental Protection Agency (EPA) for the following products: Engenia, Fexapan and Xtendimax with VaporGrip Technology. These labels establish a June 30 cutoff for applications of these products in South Dakota for the 2019 growing season. Applicators can use these products until soybeans reach the R1 growth stage, 45 days after planting or June 30, whichever comes first.
“While the weather has had an impact on planting this year, which I know is frustrating for many producers, the fact remains that warmer conditions in July increase the risk of volatility and drift when using dicamba products. The cutoff date is based on data which supports increased risk of drift after July 1,” says Secretary of Agriculture Kim Vanneman. “I encourage producers to explore the other products available to them once the cutoff date for use of dicamba has passed.”
Anyone applying Engenia, Fexapan or Xtendimax with VaporGrip Technology must also abide by the restrictions included in the EPA labels for those products, including recordkeeping requirements. Additionally, applicators applying or purchasing these products will have to complete annual dicamba specific training. Trainings can be found on the SDDA website at https://sdda.sd.gov/ag-services/dicamba/.
Agriculture is a major contributor to South Dakota’s economy, generating $25.6 billion in annual economic activity and employing over 115,000 South Dakotans. The South Dakota Department of Agriculture’s mission is to promote, protect and preserve South Dakota agriculture for today and tomorrow.

IN-CROP DICAMBA USE SUBJECT TO NORTH DAKOTA-SPECIFIC REQUIREMENTS
May 2, 2019
BISMARCK – Agriculture Commissioner Doug Goehring is reminding producers that the North Dakota Department of Agriculture (NDDA) has developed a 24c Special Local Needs (SLN) label for the in-crop use of Dicamba on soybeans. The federal label would only allow for in-crop applications no more than 45 days after planting or prior to beginning bloom (R1 growth phase), whichever comes first. The North Dakota 24c SLN allows applications of Dicamba on soybeans through June 30 or beginning bloom (R1 growth phase), whichever comes first.
In October 2018, the Environmental Protection Agency (EPA) announced it has extended the registration of Dicamba for two years for over-the-top use in Dicamba-tolerant soybeans, while also making new changes to the label.
The other label changes made by the EPA for the Dicamba formulations of XtendiMax, Engenia, and FeXapan are as follows:
- Two-year registration (until Dec. 20, 2020)
- Only certified applicators may apply Dicamba over the top (those working under the supervision of a certified applicator may no longer make applications)
- Applications will only be allowed from 1 hour after sunrise to 2 hours before sunset
- In counties where endangered species may exist, the downwind buffer will remain at 110 feet and there will be a new 57-foot buffer around the other sides of the field (the 110-foot downwind buffer applies to all applications, not just in counties where endangered species may exist)
- Clarifies training period for 2019 and beyond, ensuring consistency across all three products
- Enhanced tank clean out instructions for the entire system
- Enhanced label to improve applicator awareness on the impact of low pH’s on the potential volatility of Dicamba
- Label clean up and consistency to improve compliance and enforceability
“As a best management practice, farmers should strongly consider good weed management strategies such as pre-plant and pre-emerge products,” Goehring said. “Farmers should not rely solely on post-emergence applications of Dicamba or any herbicide for weed control.”
The new protocols will only affect applications made on soybeans for XtendiMax, Engenia, and FeXapan. The restrictions will not affect generic Dicamba on other crops.
