The Texas Department of Agriculture will require special training in 2018 for new auxin herbicides applied under a Section 3 approval on dicamba-tolerant and 2,4-D-tolerant cotton. To meet this requirement, the Texas A&M AgriLife Extension Service in Hockley, Cochran and Lamb counties will host a series of trainings:

  • Jan 22 Levelland Extension Office 10a
  • Jan 25 Ag Producers Coop Annual Mtg, Olton Ag Pavillion
  • Jan 26 Littlefield Show Barn 10a
  • Feb 21 Levelland Extension Office 9a
  • Feb 21 Littlefield Show Barn 1p
  • Feb 26 Morton County Extension Office 10a
  • March 21 Littlefield Show Barn 9a
  • March 21 Levelland County Extension Office 1p
  • March 22 Morton County Extension Office 10a

The programs will each be one hour in length (see times above).There will be no registration fee. Each class will provide one TDA continuing education unit on laws and regulations.

TDA is requiring auxin-specific herbicide training for those using the new formulations of dicamba (Xtendimax, FeXapan and Engenia).The auxin training is required for all applicators including licensed applicators and unlicensed applicators who spray under a licensed applicator. Xtendimax, FeXapan and Engenia were approved for use in XtendFlex, the dicamba-tolerant cotton from Monsanto.

Training is not required for the use of Enlist, the new 2,4-D tolerant cotton from Dow AgroSciences. However, the information provided will still be applicable for producers planning to use Enlist technology. Enlist is included in several varieties in the PhytoGen Cottonseed company brand while XtendFlex is in several varieties from Deltapine, Americot/NexGen, All-Tex/Dyna-Gro and CROPLAN Genetics brands.

The training is not required for old formulations such as Weedmaster, Clarity or Banvel, because these products are NOT labelled for use in cotton. Last year there were issues in other cotton-growing regions. Fortunately, there were very few issues reported in Texas.

As we plan for our 2018 cotton crop, we want to be proactive and promote stewardship of the new dicamba formulations so we can maintain the technology in Texas. Environmental Protection Agency approved the registration for XtendiMax, FeXapan and Engenia, as a two-year conditional registration.
