Washington Pesticide Laws and Safety Exam With Complete
Solutions 100% Correct Latest Update
What is a serious pest? - ANSWER A pest present in populations that are constantly
above the economic injury level in the absence of control.
What is an occasional or secondary pest? - ANSWER A pest that can only cause damage
above economic injury levels at specific times.
What is a potential pest? - ANSWER A pest that usually would not cause any apparent
economic damage under normal conditions.
What is a migratory pest? - ANSWER A pest that can cause serious economic damage
on a periodic basis.
What is the five steps of developing an IPM program? - ANSWER 1. Identify pest to be
managed.
2. Define management system.
3. Develop pest management strategy.
4. Develop reliable monitoring techniques.
5. Use economic thresholds.
What is the economic threshold? ANSWER The level or density of a pest population
where control measures must be applied in order 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 cultural controls? - ANSWER The use of resistant plants and animals to attack
by pests. Ex: Traditional plant breeding techniques combined with genetic manipulation
of plants to encourage host plant resistance to pests and disease.
What are biological control methods? - ANSWER Entail 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 Utilize 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 Control of nematodes.
Piscicides - ANSWER Control of pest fish.
Rodenticides - ANSWER Control of rodents.
Although not considered pesticides by definition what three classes of chemicals are
also regulated and classified as such? - ANSWER 1. Defoliants: Chemicals which forces
leaves or foliage to drop from a plant.
2. Dessicants: Chemicals which forces drying or loss of moisture in plant tissues.
3: Growth Regulators: Substance (other than fertilizers or food) which modifies the
growth or development of a plant or animal.
Adjuvants are regulated as pesticides in Washington state. What are adjuvants? -
ANSWER Substances added to the pesticides formulations and tank mixtures to
increase safety or effectiveness.
Define systemic pesticides: - ANS Products that are foliar or root absorbed then
translocated throughout the plant. These types of products can provide control of
certain pests in livestock through ingestion or injection.
Define contact pesticides: - ANS Are neither absorbed nor translocated within treated
plants or animals. The pesticide must contact the organism being controlled.
