WASHINGTON PESTICIDE LAWS UPDATED FINALS PAPER
QUESTIONS AND SOLUTIONS GUARANTEE A+
✔✔What are chemical control methods? - ✔✔Involve the use of naturally or
synthetically derived chemicals that, kill, attract, repel, or otherwise manage the growth
of a pest.
✔✔Avicides - ✔✔Management of birds.
✔✔Bactericides - ✔✔Management of bacteria.
✔✔Fungicides - ✔✔Management of fungi.
✔✔Herbicides - ✔✔Management of plants.
✔✔Insecticides - ✔✔Management of insects and insect relatives.
✔✔Miticides - ✔✔Management of mites.
✔✔Molluscicides - ✔✔Management of snails and slugs.
✔✔Nematicides - ✔✔Management of nematodes.
✔✔Piscicides - ✔✔Management of pest fish.
✔✔Rodenticides - ✔✔Management of rodent populations.
✔✔Although not considered pesticides by definition, what three classes of chemicals
are also regulated and classified as such? - ✔✔1. Defoliants: Chemicals that cause
leaves or foliage to drop from a plant.
2. Dessicants: Chemicals that promote drying or loss of moisture in plant tissues.
3: Growth Regulators: Substances (other than fertilizers or food) that alter the growth or
development of a plant or animal.
✔✔Adjuvants are regulated as pesticides in Washington state. What are adjuvants? -
✔✔Substances added to the pesticides formulations and tank mixtures to increase
safety or effectiveness.
✔✔Define systemic pesticides: - ✔✔Products that are foliar or root absorbed and then
translocated throughout the plant. These types of products can provide control of certain
pests in livestock through ingestion or injection.
✔✔Define contact pesticides: - ✔✔Are neither absorbed nor translocated within treated
plants or animals. The pesticide must contact the organism being controlled.
, ✔✔What does FIFRA stand for? - ✔✔Federal Insecticide Fungicide and Rodenticide Act
✔✔What are legal control methods? - ✔✔Limit the development of pest populations by
restricting human activities. This is accomplished by a series of laws that establish a
series of framework and quarantines to prevent the introduction of new pests within the
country.
✔✔Which federal institutions regulate legal controls? - ✔✔At the federal level, the
Animal and Plant Health Inspection Service (APHIS), and the WSDA at the state level.
✔✔Under Washington state law, what is a pesticide? - ✔✔Any substance or mixture of
substances intended to:
1. Prevent, destroy, control, repel, or mitigate any pest organism, whither it be plant,
animal, or virus (except viruses in or on humans or other animals).
2. Be used as a plant regulator, defoliant, or dessicant.
3. Or be used as a spray adjuvant (not included in the federal definition of a pesticide).
✔✔Pesticide registrations by the EPA: - ✔✔Most pesticides are registered by the EPA
and classified at general or restricted use.
✔✔Pesticide registration by the WSDA: - ✔✔Any pesticide sold or used in Washington
must be registered by the EPA. The WSDA can refuse to register pesticides regardless
of that products EPA registration status.
✔✔What is state restricted use? - ✔✔The WSDA may restrict the use of some
pesticides even though the EPA has registered them as general use.
✔✔What is SLN or 24c? - ✔✔Special local needs registrations allow a state, under
some conditions, to register additional uses for a federally registered pesticide. This
may adding application sites, pests, or alternate control techniques to those listed on
the federally registered label.
✔✔What must an applicator have to make a SLN application? - ✔✔The applicator must
have a copy of the SLN label to present to perform this type of application.
✔✔What is section 18? - ✔✔Emergency exemption from registration: Is used when an
emergency situation arises for which no acceptable pesticide is registered or available
in the state. This provision allows for the sale and use for a nonregistered purpose in a
specified area for a specified time period. Special restrictions generally accompany the
use of these products (record keeping, safety precautions, specified rates, limited
certification).
✔✔Pesticide use clause: - ✔✔No person shall transport, handle, store, load, apply, or
dispose of any pesticide, pesticide container, or apparatus in such a manner to cause
