RCW 15.160.040

(1) A seed bailment contract or seed purchase contract does not create a possessory security interest in goods under the uniform commercial code, chapter 62A.9A RCW. For a seed bailment contract, filing, recording, or notice of the contract is not a requirement for establishing, during the term of the contract, the validity of the contract or for establishing and confirming in the turf seed dealer the title to all seed, seed stock, and plant life grown or used by the bailee under the terms of the contract.

(2) Payments due from a turf seed dealer to a bailee under the terms of a seed bailment contract, or due to a turf seed producer under the terms of a turf seed purchase contract, are subject to lien under chapter 60.11 RCW and to security interests perfected as provided under Title 62A RCW.
