WASHINGTON PESTICIDE LAWS AND
SAFETY EXAM 2026 QUESTIONS WITH
CORRECT ANSWERS GRADED A+
⩥ What is an occasional or secondary pest? Answer: A pest that can
cause damage above economic injury levels only at certain times.
⩥ What is a potential pest? Answer: A pest that typically causes no
apparent economic damage under normal circumstances.
⩥ What is a migratory pest? Answer: A pest that may cause serious
economic damage on a periodic basis.
⩥ What are the five steps of developing an IPM program? Answer: 1.
Identify the pest to be managed.
2. Define the management system.
3. Develop the pest management strategy.
4. Develop reliable monitoring techniques.
5. Use economic thresholds.
⩥ What is an economic threshold? Answer: The level or density of a pest
population where control measures need to be applied to prevent the pest
from reaching the economic injury level.
,⩥ What is an economic injury level? Answer: The pest population
density that causes losses equal to the cost of the control measures.
⩥ What are mechanical control methods? Answer: Devices that prevent
the spread or reduce the infestation of pests, primarily insects and
vertebrate animals. Mechanical controls include hand destruction, traps,
and mechanical exclusions such as screens, nets, and fences.
⩥ What are physical control methods? Answer: The manipulation of
water, humidity, temperature, electric shock, or other radiant energy to
kill, alter the pests life cycle, or create an unfavorable environment for
the pest to live in.
⩥ What are cultural control methods? Answer: The manipulation of the
environment to avert serious pest damage. Cultural control methods
require knowledge of the plants needs and potential problems. Ex:
irrigation management, rotating crops, pruning, cover crops, etc.
⩥ What are generic control methods? Answer: The use of plants and
animals that are resistant to attack by pests. Ex: Traditional breeding
techniques combined with genetic manipulation of plants to promote
host plant resistance to pests and disease.
, ⩥ What are biological control methods? Answer: Involve the
introduction, encouragement, and/or artificial increase of plants and
insects/animals that are parasites or predators of a pest species.
⩥ What are chemical control methods? Answer: Involve the use of
naturally or synthetically derived chemicals that, kill, attract, repel, or
otherwise manage the growth of a pest.
⩥ Avicides Answer: Management of birds.
⩥ Bactericides Answer: Management of bacteria.
⩥ Fungicides Answer: Management of fungi.
⩥ Herbicides Answer: Management of plants.
⩥ Insecticides Answer: Management of insects and insect relatives.
⩥ Miticides Answer: Management of mites.
⩥ Molluscicides Answer: Management of snails and slugs.
⩥ Nematicides Answer: Management of nematodes.
