Cal. Food & Agric. Code § 5264

If the department determines that an invasive pest has entered the state and the urban aerial application of a pesticide, or a communitywide ground application of a pesticide, is the preferred eradication, control, or management response, the department shall advise the Governor and provide the Governor with a copy of the plan for that invasive pest. If a plan has not been prepared for that invasive pest, the department shall consult with the appropriate agencies and shall advise the Governor of the lack of a plan and advise the Governor of the best available options.
