This online course covers the application requirements for the use of approved dicamba and 2,4-D auxin formulations. Upon completion of this course, participants will be able to:
- Discuss the reasons auxin herbicides require additional precautions
- Identify label requirements for approved auxin formulations
- Describe the effects of temperature inversions of auxin formulations
- Describe practices for spray system hygiene
- Identify the record-keeping requirements for auxin
This training satisfies the US EPA requirement for mandatory dicamba applicator training as well as the Texas Department of Agriculture (TDA) requirement for auxin-specific training for approved dicamba and 2,4-D formulations. This training is not a substitute for the state-specific Certified Applicator training, which is required to purchase and use Restricted Use Pesticides. Additionally, this training qualifies for 1 CEU of laws and regulations, and successful certification permits the use of approved auxin formulation for the 2023 season only.
To receive the certificate of completion for this course, participants must obtain a score of 100% on the online Auxin Specific Applicator Test. Participants may retake the test as often as necessary.
