QUESTIONS AND SOLUTIONS GUARANTEE A+
✔✔C3: Define "integrated pest management" (IPM) - ✔✔Integrated Pest Management
(IPM) is an approach to controlling a specific pest in a specific setting that makes use of
current pest information, regular monitoring, & recordkeeping to determine if & when
action against the pest is needed. IPM uses a combination of control strategies
(biological, mechanical, cultural, physical, genetic, regulatory, & chemical) to prevent
unacceptable damage or annoyance. The control options used should be the most
effective with the least risk to people & the environment, yet provide viable options to
produce a quality, economical, & safe crop or maintain a clean, healthy indoor or
outdoor setting.
✔✔C3: List five major components of "integrated pest management" - ✔✔1) Identify the
pest & understand its biology, 2) Set up a monitoring program, 3) Know the available
control strategies, 4) Implement an IPM program, & 5) Record & evaluate results.
✔✔C3: Describe the concepts of economic & action threshold levels - ✔✔The economic
threshold level is the pest population density (number of pests per unit area) at which
control measures are needed to prevent the pest from reaching the economic injury
level; primarily in agricultural & ornamental pest control. An action threshold is the pest
level at which some type of pest management action should be taken; more appropriate
if you are not directly involved in production. It is a predetermined pest level that is
considered to be unacceptable.
✔✔C3: List several possible control tactics that may be used in an IPM strategy - ✔✔1)
Biological, 2) mechanical,
3) cultural, 4) physical,
5) genetic, 6) regulatory, &
7) chemical strategies.
✔✔C3: Discuss how pesticides can come in contact & move within target pests -
✔✔Once a pesticide comes in contact with the target species, it can move in various
ways . SYSTEMIC pesticides, once they are absorbed through the leaves or roots, are
translocated within the treated plant. CONTACT pesticides must directly touch the pest
or a site the pest frequents to be effective.
✔✔C3: Recognize the steps to take to minimize the development of pesticide resistance
- ✔✔Using different pest management strategies can help prevent or delay the
occurrence of pesticide resistance. One tactic is to use products with different MODES
OF ACTION to reduce the likelihood of resistance developing in a population. Changing
pesticide use PATTERNS is another step that can be taken to prevent resistance
development. An effective resistance management plan is based on knowing the
pesticide treatment HISTORY. ALTERNATIVE pest management techniques should be
, used to control resistant populations, hopefully to extend & prolong the use of current
pesticides.
✔✔C4: Define "label" - ✔✔The pesticide LABEL includes all the info printed on &
attached to the pesticide container or referred to on the label or accompanying
literature;
✔✔C4: Discuss why it is important to read & understand the label - ✔✔The purpose of
the label is to clearly explain info on handling, storage, use, & disposal of pesticides.
Because the label is a legal document, failure to read & follow that info can result in
legal action.
✔✔C4: Differentiate between the types of pesticide registration - ✔✔Section 3 of FIFRA:
most comprehensive registration, EPA has reviewed & approved all info; Section 24(c):
Iowa can limit uses or register additional uses of a federally registered pesticide, Special
Local Need (SLN); Section 18 emergency exemption: a state may petition EPA for a
particular product to address pest problems for which no pesticides are registered,
these needs are usually based on specific public health quarantine emergency or other
crises; Section 25(b): considered to pose minimum risk to humans and the environment
(cinnamon, garlic, salt, etc), does not require EPA label approval & does not undergo
review by the agency.
✔✔C4: Distinguish between "active" & "inert" ingredients - ✔✔"ACTIVE ingredients" the
part of the product responsible for controlling the target pest; "INERT ingredients" the
part of the product that does not provide activity against pests.
✔✔C4: Identify the common, chemical, & brand names of active ingredients in a
pesticide from a product label - ✔✔Common: Imidacloprid, Chemical: 1[(6-Chloro-3-
pyridininnyl) methyl]-N-..., Brand: BUGG-OUT
✔✔C4: Identify the meaning of "restricted use" classification & explain where to look for
it in pesticide labeling. - ✔✔Restricted use pesticides demand special attention as they
could harm humans, livestock, wildlife, or the environment, EVEN WHEN used
according to label directions; where to look for statement on label - at the top of the front
panel of the pesticide label.
✔✔C4: Interpret the signal words & symbols on pesticide labeling - ✔✔An indication of
the relative acute toxicity of the product to humans & animals. Signal words & symbols:
DANGER-POISON [Poison in red] (skull & crossbones) - can cause death in very low
doses; DANGER - can cause SEVERE eye damage or skin irritation; WARNING - is
MODERATELY toxic either orally, dermally, or through inhalation, or causes moderate
eye or skin irritation; CAUTION - is SLIGHTLY toxic either orally, dermally, or through
inhalation, or causes slight eye & skin irritation.
