This self-paced, online course examines best management practices to ensure proper application of synthetic auxin herbicides such as 2,4-D and dicamba. Upon successful completion of this course, you will be able to obtain a training certificate that will be required in order to purchase any of the approved dicamba products: Engenia, XtendiMax, or FeXapan.


This course contains four short, self-paced modules. Each module has a final quiz at the end. You must obtain a score of at least an 80% on the final quiz at the conclusion of the first three modules to obtain your certificate of completion. The fourth module is optional. You may work through the modules at your own pace; they do not all have to be completed at the same time.
