Purpose: This rule-making order amends WAC 16-350-035 by (1) requiring that rootstock from out-of-state certification programs be propagated directly from mother plants that were tested and found free of all known virus and virus-like diseases; (2) requiring that all prunus seed, except peach seed, used in the propagation of certified fruit trees originate from registered seed trees (peach seed originating from commercial sources may be used if the seed is tested and found to contain no more than 5% seed-borne viruses); and (3) clarifying existing language so that it is easier to read and understand.
