Which pesticide formulation is most often used in households, back yards and
other small areas? - ANSWER-Aerosol
Which pesticide formulation can be dangerous if its container is punctured or
overheated? - ANSWER-Aerosol
Why are dust formulations usually not used outdoors on a large scale? -
ANSWER-They may drift away from the target area
Which is not a type of pest that poisonous bait formulations are used to control?
- ANSWER-Centipedes and millipedes
For which type of job are dusts not often used? - ANSWER-To treat
recreational turf areas
Why are poisonous baits often used in small amounts? - ANSWER-baits are
needed only where pests gather
True or False: Granular formulations are made of larger, more uniform particles
than dust formulations. - ANSWER-True.
,What advantages do granules have over dusts and sprays? - ANSWER-Drift
less
Application is simpler
They penetrate dense foliage better
Why wouldn't you choose a granular if you were going to treat a tree or lettuce
crop? - ANSWER-Not enough will stick to the leaves.
What formulation would you choose if you wanted little visible residue and
only moderate agitation? - ANSWER-Emulsifiable concentrate
Why choose a low concentrate liquid formulation if you want to be sure to get
the right mixture? - ANSWER-It is ready to be sprayed as purchased
Which formulation is very hazardous because it is highly concentrated and
absorbed easily by the skin? - ANSWER-Emulsifiable concentrate
What is the difference between emulsifiable concentrates and flowables? -
ANSWER-Flowables start as solids: emulsifiable concentrates start as liquids
Would you choose an EC or a WP if phytotoxicity might be a problem? -
ANSWER-WP
True or False: You should wear a respirator when mixing soluble or wettable
powders. - ANSWER-True
What formulation would you choose if you wanted to penetrate cracks, soil,
burrows, and enclosed areas? - ANSWER-Fumigant
What are disadvantages of fumigants? - ANSWER-Can be applied only in
enclosed areas
,- May be toxic enough to require full protective gear
Which pesticide formulations must be diluted before they are applied? -
ANSWER-Wettable powders and emulsifiable concentrates
When is the best time to add pesticide to the spray tank? - ANSWER-
Immediately before application
True of False: Mixing is the time when you are most likely to be exposed to
pesticide poisoning. - ANSWER-True
Through which routes of entry are you likely to be exposed during pesticide
mixing? - ANSWER-dermal and inhalation
What margin of safety ("safety factor") does the EPA use to set tolerances? -
ANSWER-100 times lower than the NOEL (No Observed Effect Level), which
is the highest dose in a dose-response study that does not cause an adverse
effect that scientists can observe. RfD (Reference Dose) is at least 100 times
lower than the NOEL.
True or False: Food may have no residues at all because the residues may have
degraded or the crop may have been treated with a minimum dose of a
pesticide. - ANSWER-True
True or False: Soil and plant surfaces may contain pesticide residue even when
they are not directly sprayed with the pesticide. - ANSWER-True
EPA sets two kinds of tolerances: ___ ___ tolerances for pesticides that
indirectly contact food; and tolerances for pesticides applied directly to food. -
ANSWER-Negligible residue, Finite
, "Pre-slaughter interval" or "pre-harvest interval" refers to the ___ ("least/most")
number of days allowed between the last pesticide application and the slaughter
or harvest day. - ANSWER-Least
True or False: No pesticide may be bought, sold or used in the United States
until it has federal registration for the product, the use and the label. -
ANSWER-True
True or False: Sometimes even small environmental changes can greatly reduce
the chances of survival for fish and wildlife. - ANSWER-True
When a pesticide evaporates and moves off target, this is called ___ ___. -
ANSWER-Vapor Drift
Do pollution and re-entry interval influence drift? - ANSWER-No. It is
influenced by Particle size, Nozzle design and orientation, humidity, height of
release, wind speed and direction, and temperature.
Why should honeybees be protected? - ANSWER-Their work as pollinators is
necessary for crop production.
True or False: Pesticide residues can build up in the bodies of animals,
including man. - ANSWER-True
True or False: Only pesticides that are applied incorrectly are likely to move
downward with rain or irrigation water into the water table below. - ANSWER-
False
True or False: A pesticide becomes a pollutant and potentially dangerous when
it is applied at a higher dose than recommended on the label or when it drifts off
target. - ANSWER-True
