This chapter does not apply to producers who produce avocados on a noncommercial basis for the producer’s home use or where the avocado trees are used only for ornamental purposes. Producers from whom assessments are collected may apply for the refund of assessment payments following the close of any marketing season in which payments have been made, and the commission shall refund assessment payments if the producer demonstrates to the satisfaction of the commission that the avocados were produced for noncommercial purposes.
