Okla. Stat. tit. 2, § 2-3-82C: Insurance requirements

A. The Board shall not issue a commercial applicator's license

until the applicant has furnished evidence of an insurance policy or

certificate by an insurer or broker authorized to do business in

this state insuring the commercial applicator and any agents against

liability resulting from the operations of the commercial

applicator. The insurance shall not be applied to damage or injury

to agricultural crops, plants, or land being worked upon by the

commercial applicator.

B. The amount of liability shall not be less than that set by

the Board for each property damage arising out of actual use of any

pesticide. The liability shall be maintained at not less than that

sum at all times during the licensing period. The Board shall be

notified fifteen (15) days prior to any reduction in liability.

C. If the furnished liability becomes unsatisfactory, the

applicant shall immediately execute new liability upon notice from

the Board. If new liability is not immediately obtained, the Board

shall, upon notice, cancel the license. It shall be unlawful for

the person to engage in the business of applying pesticides until

the liability is brought into compliance and the license reinstated.
