Mandatory Dicamba Training and Recordkeeping

The requirements have changed for purchasing and applying auxin-specific (dicamba/2,4-D) herbicides. Read on to learn how to comply with new federal label requirements and Mississippi Department of Agriculture and Commerce (MDAC) requirements for the use of the dicamba herbicides XtendiMax, FeXapan, and Engenia during the 2019 growing season, or view the Quick Links for compliance information, access to the mandatory training for purchasers and applicators, and the current version of Mississippi’s required recordkeeping form.

Overview of Federal Label Changes for 2019

• 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)
• New 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. The training is primarily offered online, though MSU-ES has conducted some face-to-face trainings.

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 2019 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 2019 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 completed Dicamba/2,4-D Herbicide Technology Training (required for purchase) in 2017 or 2018 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).

For new purchasers who will physically apply these products, MDAC will accept Dicamba Purchaser Training to cover both purchase and application during the 2019 growing season. After 2019, these individuals must complete Dicamba Applicator Training annually to comply with federal label requirements (see Applicator Requirements above).

Recordkeeping

EPA has implemented recordkeeping changes for the 2019 growing season. These changes include filling out records within 72 hours of the application.

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

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

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

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