Definitions.
The definitions in this section apply throughout this chapter unless the context clearly requires otherwise.
(1) "Agricultural commodity" means any plant or part of a plant, or animal, or animal product, produced by a person (including farmers, ranchers, vineyardists, plant propagators, Christmas tree growers, aquaculturists, floriculturists, orchardists, foresters, or other comparable persons) primarily for sale, consumption, propagation, or other use by people or animals.
(2) "Agricultural land" means land on which an agricultural commodity is produced or land that is in a government-recognized conservation reserve program. This definition does not apply to private gardens where agricultural commodities are produced for personal consumption.
(3) "Antimicrobial pesticide" means a pesticide that is used for the control of microbial pests, including but not limited to viruses, bacteria, algae, and protozoa, and is intended for use as a disinfectant or sanitizer.
(4) "Apparatus" means any type of ground, water, or aerial equipment, device, or contrivance using motorized, mechanical, or pressurized power and used to apply pesticides that are mounted, attached to, pulled, or carried on any vehicle, trailer, aircraft, vessel, or all-terrain vehicle designed primarily for transportation and movement, but does not include a device that is handheld, carried by the applicator, or placed in position for a sedentary timed or metered application.
(5) "Arthropod" means any invertebrate animal that belongs to the phylum arthropoda, which in addition to insects, includes allied classes whose members are wingless and usually have more than six legs; for example, spiders, mites, ticks, centipedes, and isopod crustaceans.
(6) "Certified applicator" means any individual who is licensed as a commercial pesticide applicator, commercial pesticide operator, public operator, private-commercial applicator, demonstration and research applicator, private applicator, limited private applicator, rancher private applicator, or any other individual who is certified by the director to use or supervise the use of any pesticide which is classified by the EPA or the director as a restricted use pesticide.
(7) "Commercial pesticide applicator" means any person who engages in the business of applying pesticides to the land of another.
(8) "Commercial pesticide operator" means any employee of a commercial pesticide applicator who uses or supervises the use of any pesticide and who is required to be licensed under provisions of this chapter.
(9) "Defoliant" means any substance or mixture of substances intended to cause the leaves or foliage to drop from a plant with or without causing abscission.
(10) "Department" means the Washington state department of agriculture.
(11) "Desiccant" means any substance or mixture of substances intended to artificially accelerate the drying of plant tissues.
(12) "Device" means any instrument or contrivance intended to trap, destroy, control, repel, or mitigate pests, but not including equipment used for the application of pesticides when sold separately from the pesticides.
(13) "Direct supervision" by certified private applicators shall mean that the designated restricted use pesticide shall be applied for purposes of producing any agricultural commodity on land owned or rented by the applicator or the applicator's employer, by a competent person acting under the instructions and control of a certified private applicator who is immediately available, even though such certified private applicator is not physically present at the time and place the pesticide is applied. The certified private applicator shall have direct management responsibility and familiarity of the pesticide, manner of application, pest, and land to which the pesticide is being applied. Direct supervision by all other certified applicators means direct on-the-job supervision and shall require that the certified applicator be physically present at the application site and that the person making the application be in voice and visual contact with the certified applicator at all times during the application. However, direct supervision for forest application does not require constant voice and visual contact when general use pesticides are applied using nonapparatus type equipment, the certified applicator is physically present and readily available in the immediate application area, and the certified applicator directly observes pesticide mixing and batching. Direct supervision of an aerial apparatus means the pilot of the aircraft must be appropriately certified.

(21) "Fungi" means all nonchlorophyll-bearing thallophytes (all nonchlorophyll-bearing plants of lower order than mosses and liverworts); for example, rusts, smuts, mildews, molds, and yeasts, except those on or in a living person or other animals.
(22) "Fungicide" means any substance or mixture of substances intended to prevent, destroy, repel, or mitigate any fungi.
(23) "Herbicide" means any substance or mixture of substances intended to prevent, destroy, repel, or mitigate any weed or other higher plant.

(29) "Limited private applicator" means a certified applicator who uses or is in direct supervision, as defined for private applicators in this section, of the use of any herbicide classified by the EPA or the director as a restricted use pesticide, for the sole purpose of controlling weeds on nonproduction agricultural land owned or rented by the applicator or the applicator's employer. Limited private applicators may also use restricted use pesticides on timber areas, excluding aquatic sites, to control weeds designated for mandatory control under chapters 17.04, 17.06, and 17.10 RCW and state and local regulations adopted under chapters 17.04, 17.06, and 17.10 RCW.
