A. No person shall conduct field tests using a pesticide not registered with the department or a registered pesticide for a use not previously approved in the registration without first having obtained an experimental use permit from the department.

B. Any person may apply to the department for an experimental use permit for a pesticide. The department may issue an experimental use permit if it determines that the applicant needs the permit in order to accumulate information necessary to register a pesticide. The department may refuse to issue an experimental use permit if it determines that issuance of such permit is not warranted or that the pesticide use to be made under the proposed terms and conditions may cause unreasonable adverse effects on the environment.

C. Use of a pesticide under an experimental use permit shall be under the supervision of the department and shall be subject to the terms and conditions and be for the period of time prescribed by the department in the permit.

D. The department may revoke any experimental use permit at any time, if it finds that the terms or conditions of the permit are being violated, or that its terms and conditions are inadequate to avoid unreasonable adverse effects on the environment.
