Frequently Asked Questions

  1. How long will the Stop Sale, Use or Removal Order be in effect?

    Special Local Need labels are now in place for ENGENIA, XTENDIMAX and FEXAPAN in Missouri and will expire on Dec. 1, 2017.

    For all older Dicamba containing products labeled for agricultural uses, the order will remain in effect until Dec. 1, 2017.

  2. Why was this order issued?

    Based upon feedback from across Missouri and neighboring states and continued reports of crop damage, the Department felt it would be best to temporarily stop the sale and use of Dicamba products until a Special Local Need label is developed and approved.

  3. Are homeowner lawn and garden Dicamba containing herbicides included under the Stop Sale, Use or Removal Order?

    No. Only Dicamba products labeled for agricultural uses are included.

  4. As a farmer and/or retailer with an inventory of Dicamba products, what should I do with my inventory of Dicamba?

    Refer to the “storage and disposal” section found on each pesticide label and store your product in accordance with the label directions.

  5. What are the penalties for a retailer or applicator who violates the Stop Sale, Use or Removal Order?

    Section 281.060 RSMo gives the Director of Agriculture the authority to assess a civil penalty.

  9. What does Dicamba do?

    Dicamba is an active ingredient contained in certain herbicides. Herbicides containing Dicamba are registered for uses in agriculture, residential areas, and other sites to address broadleaf weeds and woody plants.

  10. What is a Special Local Need label?

    The Department has the authority under section 24(c) of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) to register an additional use of a federally registered pesticide product, or a new end use product for use in “special local need” situations.

    These registrations, reviewed and issued by MDA, become federal registrations under Section 3 of FIFRA, but can only be distributed and used within the state of Missouri.

    A Special Local Need label is typically used to allow specific pesticide use in the state with special provisions.

  11. How do I contact the manufacturer of my Dicamba product?

    Manufacturer-specific information can be found on the product label.

  12. How do I know if my pesticide is impacted?
