Dicamba Facts image

On Oct. 13, 2017, the U.S. Environmental Protection Agency (EPA) announced an agreement with Monsanto, BASF and DuPont on measures to minimize the potential for off-target movement of Dicamba and further ensure effective use of three pesticides: DuPont’s FeXapan, BASF’s Engenia and Monsanto’s XtendiMax.

In a collaborative effort to safeguard Missouri agriculture, the Missouri Department of Agriculture issued a 24c Special Local Need label for ENGENIA Herbicide on Nov. 16, 2017, EPA Registration Number 7969-345 – SLN label MO-180001. The Department subsequently issued 24c Special Local Need labels for XTENDIMAX, EPA Registration Number 524-617, and FEXAPAN, EPA Registration Number 352-913, on Dec. 11, 2017. All three labels contain the same restrictions.

The Missouri Department of Agriculture announced the following Missouri-specific restrictions for ENGENIA, XTENDIMAX and FEXAPAN:

Dates and locations for in-person training:

  • Jan. 10 - Ramada Plaza Hotel and Oasis Convention Center, 2546 N. Glenstone, Springfield.

If you are a private applicator (farmer) producing agricultural commodities, you are required to complete certified private applicator training provided by University of Missouri Extension. Contact your local county extension center to register for the next available training session. Following the completion of private applicator training, the extension center will send your application for license to the Missouri Department of Agriculture for issuance of a certified private applicator license.

If you are a pesticide applicator engaged in the business of applying pesticides for hire in exchange for a fee or other compensation, you must obtain a certified commercial applicator license through the Missouri Department of Agriculture. Please visit our certification and licensing webpage for more information.

Dicamba Notice of Application

Certified applicators must complete an online Notice of Application form daily prior to each application. This means that applicators are required to submit one Notice of Application for each field they will be spraying, each day they are spraying it. For example, if you will be making five applications to five different fields on one day, you are required to submit five separate Notices of Application.

Proposed Pesticide Emergency Rule

The Missouri Department of Agriculture hosted a public hearing on Wednesday, March 21, at which interested parties shared their input on a proposed emergency rule to restrict the sale of certain pesticides in Missouri. Written comments were also accepted.

An emergency rule is still being considered, but no decision has been made yet.

The Department is working diligently to review all comments and develop a path forward that promotes and protects technology, both old and new. Whatever the decision, the Department will work closely with stakeholders to share the information.

Report Pesticide Drift Damage

The Missouri Department of Agriculture is responsible for regulating the use of pesticides in the state of Missouri. This is established in Sections 281.005 to 115 (RSMo) of the Missouri Pesticide Use Act. To report pesticide drift damage on your farm or property, please visit the Pesticide Incident Report page.
