Mandatory Dicamba Training and Recordkeeping

Read below to learn how to comply with federal label and Mississippi Department of Agriculture and Commerce (MDAC) requirements for the use of the dicamba herbicides XtendiMax, FeXapan, and Engenia during the 2020 growing season or view the Quick Links for access to the mandatory training for purchasers and applicators and the current version of Mississippi’s required recordkeeping form. 

Federal Label Changes for 2019 Remain in Effect for 2020

  • Only certified pesticide applicators may apply these 3 products (XtendiMax, FeXapan, and Engenia); in other words, applicators can no longer work ‘under the supervision of’ a certified applicator
  • Generate application records within 72 hours of application
  • Daytime application only (1 hour after sunrise until 2 hours before sunset)
  • Buffers for endangered species protection
  • Susceptible crop language
  • Updated postemergence window
  • Minimum spray volume (15 gallons per acre)
  • Updated sensitive areas, sensitive crops, and residential areas
  • Updated 24-hour rainfall amount

Mandatory Training

Both purchasers and applicators of these products must complete training provided free of charge by Mississippi State University Extension Service, the only provider approved by MDAC. See below for specific training requirements for new purchasers, applicators, and those who will both purchase and physically apply these products.

Purchaser Requirements

To purchase auxin-containing herbicides for in-crop use during the 2020 growing season, individuals must:

  • Hold an active pesticide applicator certification
  • Complete one-time Dicamba/2,4-D herbicide technology training (if not taken previously)

New purchasers can access the training by clicking here. Fill out the registration information and complete Dicamba Purchaser Training. After successful completion of the training, individuals will receive email verification from MDAC and endorsement on their pesticide certification.

Applicator Requirements

Applicators who plan to apply the dicamba herbicides XtendiMax, FeXapan, and Engenia during the 2020 growing season MUST complete label-required annual applicator training. To access Dicamba Applicator Training, click here. After successfully completing the training, individuals will receive notice of completion that must be kept for 2 years.

Applicators of these dicamba herbicides must hold current pesticide applicator certification. Individuals who need to become certified can attend a Private Applicator Training (fee $20). After successfully passing the exam, MDAC will issue a private applicator certification, which is good for 5 years. Private Applicator Trainings are conducted around the state by Extension agents. See Upcoming Events in the sidebar on the right for the Private Applicator Training schedule or contact your local Extension office.

Purchaser/Applicator Requirements

Some individuals will both purchase and physically apply these auxin-containing herbicides.

Purchasers who previously completed Dicamba/2,4-D Herbicide Technology Training (required for purchase) do NOT need to take purchaser training again, but they MUST complete Dicamba Applicator Training annually to comply with federal label requirements (see Applicator Requirements above).


Mississippi’s mandatory recordkeeping form for Engenia, FeXapan, and XtendiMax applications has been updated for the 2020 growing season. The 2020 form reflects federal label changes implemented in 2019, including

  • pesticide certification for all applicators
  • 72-hour window for completing the application record
  • buffer requirements for endangered species protection

A separate form must be filled out for each application. Application records must be retained for 2 years.

For each applicator, confirmation of completion of Dicamba Applicator Training must also be kept for 2 years.
