  (5) The following are restrictions on use and distribution of state-limited-use pesticides and regulated herbicides:
    (A) A person may not purchase or use a pesticide classified as a state-limited-use pesticide or as a regulated herbicide under this subsection unless the person is licensed as a pesticide applicator under either the Act or working under the direct supervision of a person so licensed, or Chapter 1951 of the Texas Occupations Code.
    (B) A person may not distribute a pesticide classified as state-limited-use or as a regulated herbicide under this subsection to a person not authorized by this section to purchase state-limited-use pesticide or a regulated herbicide.
    (C) A person may not apply 2,4-dichlorophenoxyacetic acid (2,4-D) on a transgenic auxin herbicide tolerant crop unless the person has attended an auxin training course approved by the department prior to application.
      (i) One (1) 2,4-D continuing education unit (CEU) shall be required annually and is valid for one year from the date of course attendance.
      (ii) Courses shall be approved by the department and may not be less than 50 minutes in length for each active ingredient. No more than one (1) CEU will be assigned for any 50 minutes of actual instruction time in Laws and Regulations as described in §7.24 of this chapter (relating to Applicator Recertification).
      (iii) Each course shall include topics on: application timing, nozzle requirements/selection, wind speed, ground speed, boom height, tank cleanout, sensitive crops, buffer zone requirements, weather conditions, drift, volatility, and inversion.
    (D) A person may not apply 3,6-Dichloro-o-anisic acid (dicamba) on a transgenic auxin herbicide tolerant crop unless the person has attended an auxin training course approved by the department prior to application.
      (i) One (1) dicamba continuing education unit (CEU) shall be required annually and is valid for one year from the date of course attendance.
