The following definitions shall apply to WAC 16-470-101 through 16-470-130:

(1) "Established" means present in a country, state, county or other area, multiplying and expected to continue.

(2) "Host plant" means all species in the genera of Malus, Crataegus, Prunus, Pyrus and Cydonia (including, but not limited to, apples, crab apples, hawthorn, cherries, plums, prunes, pears, and quince).

(3) "Soil" and "growing medium" as regulated commodities means only that soil or growing medium in pots or on root balls of plants originating from a quarantined area being shipped under this quarantine.

(4) "Threatened with infestation" means that any life stage of apple maggot or plum curculio has been found within one-half mile of an orchard or other production site, including any portion of an orchard outside or beyond the one-half mile area. Orchards or production sites in a quarantined area, which are not surveyed by a plant protection organization, are considered to be threatened with infestation. An orchard or other production site will be removed from threatened with infestation status, if control measures are performed at the detection site, and survey by the department shows no further detection(s) within the one-half mile area around the orchard or other production site throughout the subsequent full growing season.
