Yolo County’s official nut buying season runs from August 1 to April 1, 2026, as set by Agricultural Commissioner Humberto Izquierdo. The season covers the trade of almonds, walnuts, and pistachios and is intended to help regulate sales and prevent theft, according to the Yolo County.
Yolo County requires sellers and buyers of unprocessed nuts to provide Proof of Ownership under a 2014 ordinance aimed at preventing nut theft. The document must include names, addresses, phone numbers, signatures, vehicle and driver’s license numbers, the weight of the nuts, the date and time of the transaction, the nut variety and condition, and the source. The Yolo County Agricultural Commissioner’s office and peace officers may conduct compliance checks and request this documentation when there is probable cause.
Nut commodities in Yolo County must have required documentation at all times, with forms available from the Yolo County Agriculture Department or the Yolo County Farm Bureau. Local law enforcement and the Agricultural Commissioner’s office will enforce these regulations during the nut buying season.
