OH PESTICIDE CERTIFICATION – CORE 2025-2026
UPDATED ACTUAL EXAM WITH CORRECT
SOLUTIONS.
Apest can be anything that:
| | | | |
a. Competes with humans, domestic animals or desirable | | | | | |
plants for food or water
| | | | |
b. Injures humans, animals, desirable plants, structures, or | | | | | |
possessions
|
c. Spreads disease to humans, domestic animals, wildlife, or | | | | | | |
desirable plants
| |
d. Annoys human or domestic animals | | | |
e. All of the above - correct answer- E. A pest can be anything that
| | | | | | | | | | | | |
annoys, injures, spreads disease or competes with desired
| | | | | | | |
plants, animals, or humans. Examples of pests include weeds,
| | | | | | | | |
insects, fungi, bacteria, mites and nematodes
| | | | | |
One requirement for effective pest control is:
| | | | | |
a. Identification of the pest to be controlled | | | | | |
b. New spray equipment | |
c. Using more than the recommended dosage | | | | |
d. Spraying only the field margin - correct answer- A. Identifying | | | | | | | | |
the pest is the first step. Additionally, it is necessary to know what
| | | | | | | | | | | | |
control methods are available; evaluate the benefits and risks of
| | | | | | | | | |
each method or combination of methods; choose the methods
| | | | | | | | |
that are most effective and will cause the least harm
| | | | | | | | | |
,2 | Page
| | | | | |
to people and the environment; use each method correctly; and
| | | | | | | | |
observe local, state, and federal regulations that apply to the
| | | | | | | | | |
situation.
|
Apest-control method should be used only when that method will
| | | | | | | | | |
cost less than the expected value of a loss from the pest.
| | | | | | | | | | | |
a. True
b. False - correct answer- A. Even though a pest is present, it
| | | | | | | | | | |
may not do very much harm. It could cost more to control the
| | | | | | | | | | | | |
pest than to allow the damage to occur. The point at which the
| | | | | | | | | | | | |
cost of the damage exceeds the cost of the control is the
| | | | | | | | | | | |
"economic threshold."
| |
Successful pest control is based on the ability to: | | | | | | | |
a. Eradicate all pests | |
b. Use pesticides whenever pests are identified
| | | | |
c. Contaminate the environment | |
d. None of the above - correct answer- D. The best answer
| | | | | | | | | |
should be to: 1) keep pest damage to a minimum by choosing an
| | | | | | | | | | | | |
appropriate combination of control methods, 2) recognize when
| | | | | | | |
direct action is necessary, and 3) endanger the environment as
| | | | | | | | | |
little as possible
| | |
Which of the following is NOT a pest control goal?
| | | | | | | | |
a. Prevention - keeping a pest from becoming a problem | | | | | | | |
,3 | Page
| | | | | |
b. Suppression - reducing pest numbers to an acceptable level | | | | | | | |
c. Eradication - destroying an entire pest population | | | | | |
d. All of the above are possible goals - correct answer- D.
| | | | | | | | | |
Prevention and suppression are common goals. Eradication is a
| | | | | | | | |
difficult goal to achieve, especially in outdoor areas, but may be
| | | | | | | | | | |
attempted when a foreign pest has been introduced into an area
| | | | | | | | | | |
(e.g. gypsy moth, Mediterranean fruit fly, etc.). Eradication is a
| | | | | | | | | |
more common goal in indoor areas.
| | | | | |
The strategy of combining pest control tactics into a single plan to
| | | | | | | | | | |
reduce pests and their damage to an acceptable level is called:
| | | | | | | | | | |
a. Holistic Resource Management Plan | | |
b. Biological Control |
c. Best Management Practices | |
d. Integrated Pest Management - correct answer- D. Biological | | | | | | |
control is a tactic of Integrated Pest Management (IPM). IPM is
| | | | | | | | | | |
one component of a holistic resource management plan and is
| | | | | | | | | |
an example of a Best Management Practice.
| | | | | | |
When the level of a pest population reaches the stage where pest
| | | | | | | | | | |
control action should be taken, you are at the:
| | | | | | | | |
a. Scouting stage |
b. Monitoring stage |
c. Threshold stage |
, 4 | Page
| | | | | |
d. Pesticide application stage - correct answer- C. Thresholds | | | | | | |
maybe based on aesthetic, health, or economic considerations.
| | | | | | | |
Action thresholds have been determined for many pests.
| | | | | | | |
Which of the following is NOT an example of a control tactic?
| | | | | | | | | | |
a. Pesticide resistance - the ability of a pest to resist pesticide | | | | | | | | | |
control measures
| |
b. Biological control - using natural predators to control pests | | | | | | | |
c. Cultural controls - such as crop rotation, date of planting, | | | | | | | | |
cultivation, etc.
| |
d. Chemical control - the use of pesticides - correct answer- A. | | | | | | | | | |
Do not confuse pest resistance with host resistance. Some
| | | | | | | | |
plants and animals resist pests better than others
| | | | | | | |
The ability of a pest to resist or avoid poisoning from a pesticide
| | | | | | | | | | | |
even when it has been properly applied is called:
| | | | | | | | |
a. Efficacy
b. Pesticide resistance |
c. Dormancy
d. Antagonism - correct answer- B. Each time a pesticide is used, | | | | | | | | | |
it selectively kills the most susceptible pests. Some pests are able
| | | | | | | | | | |
to withstand its effects. These pests may be able to pass along
| | | | | | | | | | | |
this trait to their offspring. Continued use of the same pesticide
| | | | | | | | | | |
may allow the resistant offspring to multiply. This phenomenon is
| | | | | | | | | |
known as pesticide resistance.
