How can pest identification help you develop a good pest control strategy? - Correct
Answers -Identification of the pest allows you to determine basic information about it,
including its life cycle and the time that it is most susceptible to being controlled.
Define "integrated pest management" (IPM) and list several possible control tactics that
may be used in an IPM strategy. - Correct Answers -Integrated pest management is the
combining of appropriate pest control tactics into a single plan to reduce pests and their
damage to an acceptable level. Pest control tactics may include: host resistance,
biological control, cultural control, mechanical control, sanitation, and chemical
(pesticide) control.
You applied a pesticide, but it did not control the pest. Name three reasons why your
control effort might have failed. - Correct Answers -The failure of the pesticide to control
the pest might have been caused by pest resistance, choosing the wrong pesticide,
misidentifying the pest, applying the wrong amount, or applying the pesticide incorrectly.
What can you do to keep the pests you are trying to control from becoming resistant to
the pesticides you use? - Correct Answers -Pest resistance can be reduced by using
integrated pest management and rotating the types of pesticides used.
What are common signs and symptoms of heat stress? - Correct Answers -Heat stress
may cause fatigue (exhaustion, muscle weakness); headache, nausea, and chill;
dizziness and fainting; severe thirst and dry mouth; clammy skin or hot, dry skin; heavy
sweating or complete lack of sweating; altered behavior (confusion, slurred speech, and
quarrelsome or irrational behavior).
What legal responsibility do you have for wearing the personal protective equipment
that the pesticide labeling lists for your handling situation? - Correct Answers -By law,
you must wear at least the personal protective equipment listed on the label for handling
the task you will be performing. You are allowed to wear additional or more personal
protective equipment.
What special hazards do fumigants pose for pesticide handlers? - Correct Answers -
Fumigants pose a serious inhalation hazard to pesticide handlers. Some fumigants also
can cause severe skin burns if they are trapped next to the skin by tight clothing or
chemical-resistant personal protective equipment.
, If you have pesticide wastes (other than empty containers) what can you do with them?
- Correct Answers -Dispose in a hazardous waste landfill or pesticide incinerator, or
store until disposal is possible.
Name four of the six available methods to control pests when natural controls are not
sufficient. - Correct Answers -The six pest control methods include: host resistance,
biological control, cultural control, mechanical control, sanitation, and chemical control.
Name the four factors that affect pesticide use outdoors. - Correct Answers -Pesticide
use outdoors is affected by soil factors, surface moisture, humidity and temperature,
and wind.
What is the best control method for controlling plant diseases? - Correct Answers -At
present, prevention is the only plant disease control measure. Once a plant is infected,
few control methods are effective, including pesticides.
Name four forms of mechanical vertebrate pest control. - Correct Answers -Traps,
barriers, gunning, attractants, and repellents are all forms of mechanical vertebrate pest
control.
What is a pesticide formulation? - Correct Answers -A pesticide formulation is the
mixture of active and inert (inactive) ingredients that forms a pesticide product.
What is the difference between active ingredients and inert ingredients? - Correct
Answers -Active ingredients are the chemicals in a pesticide product that control pests.
Inert ingredients are the chemicals in a pesticide product that are added to make the
product safer, more effective, easier to measure, mix, and apply, and more convenient
to handle.
What types of factors should you consider when you have a choice of formulations for a
pest control task? - Correct Answers -You should think about the characteristics of each
formulation, and you should consider which of the formulation's advantages and
disadvantages are important in your application situation. Also consider the following:
Do you have the right application equipment? Can you apply the formulation safely? Will
the formulation reach the target and stay in place long enough to control the pest? Might
the formulation harm the target site?
If you had a choice of either a wettable powder formulation or a granular formulation for
a particular pest control task, which would be best if drift were a major concern? Which
would be best if you need the pesticide to stay on a surface that is not level, such as
foliage? - Correct Answers -The granular formulation would be the best choice in the
first situation, because granules have a much lower drift hazard than wettable powders.
Granules do not stick to nonlevel surfaces, so the wettable powder would be the best
choice in the second situation.
