Missouri Lifts Dicamba Ban, Issues Stricter Application Parameters

Chris Chinn, Director of Missouri Department of Agriculture


The Missouri Department of Agriculture has lifted its barely week-old ban on new dicamba technologies, which have been at the center of controversy as complaints about drift snowball in select Southern states, and replaced it with a set of tightened application restrictions.

The department issued the following statement on Thurs., July 13:

Missouri Director of Agriculture Chris Chinn today issued a Notice of Release from the statewide Stop Sale, Use or Removal Order for ENGENIA Herbicide, EPA Registration Number 7969-345; XTENDIMAX with VaporGrip Technology, EPA Registration Number 524-617; and FEXAPAN™ Herbicide Plus VaporGrip™ Technology, EPA Registration Number 352-913.

“From the moment the stop sale and use order went into effect, we’ve been working to get these weed control products back into the hands of our farmers,” said Director of Agriculture Chris Chinn. “BASF, Monsanto and DuPont came to the table and agreed to additional safeguards for product use in response to issues we’ve faced this growing season.”

In an effort to reduce off-target crop injury, the Department has approved a Special Local Need label for each herbicide which includes special provisions and safeguards for the use of this technology in Missouri.

According to the Special Local Need labels, to apply the herbicide to dicamba-tolerant soybeans and dicamba-tolerant cotton in Missouri, the following restrictions must be followed:

  • Wind Speed DO NOT apply at wind speeds greater than 10 mph. Applicators must measure and record wind speed and wind direction for each field prior to application.
  • Application Timing DO NOT apply before 9:00 a.m. and DO NOT apply after 3:00 p.m.
  • Certified Applicator – All applications of ENGENIA, XTENDIMAX and FEXAPAN must be made by a properly licensed Missouri certified private applicator or certified commercial applicator, certified noncommercial applicator or certified public operator.
  • Dicamba Notice of Application Form – Certified applicators must complete an online web-based form “Dicamba Notice of Application” prior to the actual application. The Dicamba Notice of Application Form is posted on the Missouri Department of Agriculture’s website at: www.Agriculture.Mo.Gov/dicamba/notice/.
  • Recordkeeping Requirements – Certified private applicators, certified noncommercial applicators and certified public operators must keep and maintain a record of use for each application of ENGENIA, XTENDIMAX or FEXAPAN herbicide.
