Missouri issues safeguards for dicamba-tolerant herbicides


If a Missouri grower wants to apply a herbicide to dicamba-tolerant soybeans or cotton, the Missouri Department of Agriculture has now approved a Special Local Need label.

Missouri Director of Agriculture Chris Chinn today issued today a Notice of Release from the statewide Stop Sale, Use, or Removal Order on ENGENIA, XTENDIMAX, and FEXAPAN herbicides.

“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.
  • 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.

This release applies to the sale, distribution, and use of ENGENIA Herbicide, EPA Registration Number 7969-345 – SLN label MO-17-0003; XTENDIMAX with VaporGrip Technology, EPA Registration Number 524-617 — SLN label MO-17-0002; and FEXAPAN Herbicide Plus VaporGrip Technology, EPA Registration Number 352-913 — SLN label MO-17-0004. The statewide order will remain in effect until Dec. 1, 2017, for all other Dicamba containing products labeled for agricultural use.
