QUESTIONS AND CORRECT ANSWERS / A GRADE
SCORE SOLUTION
Explain the difference between key pests, occasional pests and secondary
pests - answer-Key pests are nearly always present and require regular control.
occasional pests are migratory or cyclical and require intermittent control.
secondary pests require control only under certain conditions, such as the
elimination of a key pest or the absence of a natural host.
what should you do first if you see damage to a plant, animal, or valuable
product/ - answer-identify the cause
what should you do first if you discover a pest that may need to be controlled?
- answer-make sure the pest is actually responsible for the damage. then
accurately identify the pest
what is monitoring and how is it important to a sound pest control strategy? -
answer-regular checking or scouting for pests in a designated area. Monitoring
will tell you what pests are in an area, how many are in the area, and how
much damage they are causing. it will help determine if the pest population
has reached the treatment threshold and whether control measures have
worked.
what is the difference between prevention, suppression and eradication of a
pest? - answer-prevention means reducing the chances that a pest will become
,a problem. suppression means reducing pest numbers or damage to an
acceptable level. Eradication means destroying an entire pest population.
how could you prevent a pest infestation? - answer-plant weed- and disease-
free seed, choose plants resistant to diseases and insects, and practice good
sanitation. other preventative techniques include excluding pests from the
target area and using pre-emergent herbicides to kill weed seeds.
when and why may a pesticide product be registered for a special local need
SLN? - answer-if a manufacturer wants to register a pesticide for use only on a
regional crop or to manage a localized pest problem. SLN registrations allow
states to expand or limit the uses of federally registered pesticides within their
jurisdictions.
what is a federal Section 3 registration? - answer-an EPA registered product
with a label reviewed and approved by that federal agency. Most pesticides
are registered this way. these have an EPA registration number
true or false: ALL pesticide products must be registered with EPA. This agency
reviews the labels of ALL pesticide products sold in the US - answer-False.
Minimum risk pesticides are exempt from the federal registration process.
under what conditions may a pesticide be labeled "minimum risk" and thus be
exempt form federal regulations? how do labels of minimum-risk Section 25(b)
products differ from those that are EPA registered (section 3)? - answer-EPA
has produced a list of minimal risk active and inert ingredients. to be exempt,
all of the active and inert ingredients in a pesticide product must be on this list.
, are minimum risk products exempt from Virginia's state registration
requirements? - answer-no. all pesticides that are sold or used in the
Commonwealth of Virginia must be registered with VDACS office of pesticide
services.

problems for which no pesticides are registered. section 18 exemptions allow
the sale and use of a certain pesticide for a specific nonregistered purpose for
a specified period. the four types of emergency exemptions are: specific,
quarantine, public health, and crisis.
what is a restricted use pesticide? - answer-RUPs are pesticides that require
special care and handling. the restricted use designation limits the use of a
pesticide product. RUPs are for sale only to properly certified applicators. only
trained persons, or people under their direct supervision, may handle and
apply RUPs.
EPA classifies pesticides RUPs for different reasons. Some are highly toxic to
humans. others may cause long-term health effects. still others are restricted
because of an environmental effect such as ground water pollution.
what is the difference between the chemical name, common name, and trade
name? which is the most accurate identify the active ingredient? - answer-
chemical name is a complex term that identifies the chemical components and
structure of a pesticide.
common name is a shorter name that EPA recognizes as a substitute for the
chemical name. best identifier.--ex. glyphosate
