Cal. Food & Agr. Code § 58895
A marketing order may contain provisions to detect, control, prevent damage by or to eradicate insects, predators, diseases, or parasites with respect to any commodity or group of commodities. The advisory board may recommend and the director may approve measures to assist in the prevention or reduction of losses to crops or livestock caused by predators, insects, disease or parasite infestations, including the establishment and operation of detection, inspection, spraying, dusting, fumigating or other control measures.
For the purposes of this section, (1) assessments established pursuant to Article 10 (commencing with Section 58921) of this chapter may include an assessment for nonbearing acreage as well as bearing acreage of the commodity affected by such predators, insects, disease, or parasite, and (2) the director may use both the bearing and nonbearing acreage of such commodity as a measure of production for assent or referendum purposes in relation to such assessments.
As used in this section, "nonbearing acreage" means acreage planted to produce the particular commodity covered by the marketing order during the marketing season on which no quantity of the product is produced for marketing or is anticipated will be produced for market during such marketing season.
