Food & Agr. Code, § 233

(a) The trust fund consists of moneys transferred by the director from the Department of Food and Agriculture Fund, including all income therefrom. The amount of funds, excluding interest earned thereon, contained in the trust fund shall be determined by the director, and shall be the same percentage for all agricultural programs, but shall not exceed 10 percent of the annual operating budgets of each agricultural program. Funds in excess of 10 percent of the annual operating budgets of each agricultural program that are in the trust fund, or such other lesser percentage as the director may determine, may be returned to the Department of Food and Agriculture Fund.

(b) The director shall establish separate accounts in the trust fund for the money transferred to the fund from each of the agricultural program accounts in the Department of Food and Agriculture Fund. The trust accounts shall be used by the Department of Food and Agriculture Fund for expenditure when necessary for the exclusive purpose of implementing and continuing any of the agriculture programs with money contained in the trust fund.
