*There was an error in the wind speed restrictions in the January 12th eUpdate issue. This has been corrected in this issue.

As we embark on the 2018 growing season, producers should be aware that dicamba herbicides Engenia, FeXapan, and XtendiMax have been reclassified as Restricted Use Pesticides (RUPs). In order to purchase and apply these herbicides, you must be certified as a private or 1A (Agriculture Plant) commercial pesticide applicator.  In addition, anyone planning to apply these herbicides this coming season will be required to attend dicamba or auxin specific applicator training.  In Kansas, these trainings will be sponsored by K-State Research and Extension, as well as industry representatives from BASF, Dow/Dupont, and Monsanto. It will be the responsibility of the applicators to obtain this training before the application of these herbicides.

The purpose of these trainings is to cover the label changes and application requirements in detail and provide information on what you, as an applicator, need to do to meet these requirements. The labels for these herbicides include mandatory record keeping requirements, modified wind speed restrictions (3 to 10 miles per hour only), limited times of day that applications can be made (between sunrise and sunset), a revised list of sensitive crops and sensitive sites, buffer zone requirements, and revised sprayer cleaning procedures and documentation.

The dates and locations for K-State Research and Extension sponsored trainings will be posted on the KSU-IPM website at the website listed below. Once there, click on the 2018 Dicamba Training link at the bottom of the page.
