The manufacturer or other person whose name appears on the label of the pesticide shall register the pesticide.

(d) Registration is not required for a chemical compound being used only to develop plot data as to the possible pesticidal action of the chemical.
(e) Unless otherwise required by department rule, registration is not required for a pesticide that is exempt from registration with the United States Environmental Protection Agency under federal law.
(f) The Texas Feed and Fertilizer Control Service may not register under Chapter 63 a fertilizer that contains a pesticide that must be registered with the department under this chapter unless the constituent pesticide is first registered with the department.

The department shall notify the Texas Feed and Fertilizer Control Service of any changes to a pesticide registration.
(g) Except as provided by Subsection (g-1), a pesticide that has been registered with the department must continue to be registered until the earlier of:
