WASHINGTON PESTICIDE LAWS AND
SAFETY QUESTIONS AND ANSWERS WITH
CORRECT SOLUTIONS GRADED A+
What is the difference between toxicity and hazard? - CORRECT ANSWES -- Toxicity
is a measure of the the capacity of a pesticide to cause injury. Hazard is the potential
for injury, or the degree of danger involved in using a pesticide under a given set of
circumstances.
Generally speaking, warm, moist areas of the body tend to be more absorptive. -
CORRECT ANSWES -- The head and genital areas are highly absorptive. Typically, dry
powers, dusts, and granular formulations will be less readily absorbed through the skin
than oil based liquid formulations like emulsifiable concentrates.
What is acute toxicity? - CORRECT ANSWES -- Based on a single pesticide dosage
and is determined by exposing skin the chemical, permitting a test animal to inhale the
What is a severe pest? - CORRECT ANSWES -- A pest present in populations that are
always above the economic injury level in the absence of control.
What is an occasional or secondary pest? - CORRECT ANSWES -- A pest that can
cause damage above economic injury levels only at certain times.
What is a potential pest? - CORRECT ANSWES -- A pest that typically causes no
apparent economic damage under normal circumstances.
What is a migratory pest? - CORRECT ANSWES -- A pest that may cause serious
economic damage on a periodic basis.
What are the five steps of developing an IPM program? - CORRECT ANSWES -- 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? - CORRECT ANSWES -- 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? - CORRECT ANSWES -- The pest population density
that causes losses equal to the cost of the control measures.
, What are mechanical control methods? - CORRECT ANSWES -- 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? - CORRECT ANSWES -- 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? - CORRECT ANSWES -- 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? - CORRECT ANSWES -- 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? - CORRECT ANSWES -- 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? - CORRECT ANSWES -- Involve the use of
naturally or synthetically derived chemicals that, kill, attract, repel, or otherwise manage
the growth of a pest.
Avicides - CORRECT ANSWES -- Management of birds.
Bactericides - CORRECT ANSWES -- Management of bacteria.
Fungicides - CORRECT ANSWES -- Management of fungi.
Herbicides - CORRECT ANSWES -- Management of plants.
Insecticides - CORRECT ANSWES -- Management of insects and insect relatives.
Miticides - CORRECT ANSWES -- Management of mites.
Molluscicides - CORRECT ANSWES -- Management of snails and slugs.
Nematicides - CORRECT ANSWES -- Management of nematodes.
Piscicides - CORRECT ANSWES -- Management of pest fish.
