Poteau, Okla. – Applicators planning to use specific dicamba herbicides labelled for the Roundup Ready Xtend Crop System™ for soybeans and cotton must complete U.S. Department of Agriculture-approved dicamba training before spraying these products each year.


“Whether you’re a certified applicator or driving the application equipment you have to be trained,” said Todd Baughman, Oklahoma State University Cooperative Extension summer crop weed specialist. “Even if you went through a training in previous years, you’re still required to go through the Oklahoma Department of Agriculture, Food and Forestry approved trainings every year.”


The following one-hour trainings are free of charge hosted at most county extension offices via a webinar service format however, we ask that you call ahead to reserve your spot.



For more information, including specific training locations and times, contact your nearest county Extension office.

Recently introduced to Oklahoma, the Xtend cropping system for cotton and soybeans allows over-the- top application of dicamba herbicides, which traditionally had not been the case until this newest technology was developed.

With that technology, three specific herbicides – XtendiMax, Engenia and FeXapan – were developed for this use that are lower volatility than the other dicamba products currently on the market.

Issues with drift in several states led the Environmental Protection Agency and manufacturers to develop new regulations for this technology.

The mandatory training will cover the regulations, including how to work with these herbicides, which are restricted-use products with extensive recordkeeping requirements, and best management practices for applying the herbicides.

Baughman stressed the training is important because it familiarizes people with the regulations.

“If we have any types of issues, especially to the level in past years, we could potentially lose the use of this technology for soybeans and cotton, which would be a major detriment, especially to producers who are dealing with resistant weeds,” Baughman said.
