Certification Requirements

This training satisfies the US EPA requirement for mandatory applicator training as well as the Texas Department of Agriculture (TDA) requirement for auxin-specific training for approved 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 2025 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.

• Private Applicators: Section 7.24 (v)(5) of the Texas Pesticide Laws and Regulations relating to private applicator recertification states 'A private applicator may not obtain more than 10 CEUs through correspondence activities in any five-year recertification cycle.'
