Ornamental and Turf Pest Control Exam Study
Questions with Correct Answers 2026 Update
Pest -Correct Answer ✔-unwanted organism that is a nuisance and can injure
people animals, plants, and property.
Nontarget organisms -Correct Answer ✔-Those that a pesticide applicator did
not intend to affect. ex. Pollinators, bees, butterflies, other beneficial insects,
birds, pets, or people
Integrated Pest Management (IPM) -Correct Answer ✔-An approach to pest
management in which all available necessary techniques are combined into one
program. The goal is to manage pest populations in a way that avoids economic
or aesthetic damage and has teh least adverse side effects.
Economic Injury Level (EIL) -Correct Answer ✔-The lowest pest density at which
economic damage occurs; the level where the cost of control is equal to the loss
likely to be caused by the pest.
Injury Threshold -Correct Answer ✔-The pest level population that causes
unacceptable injury.
Treatment Threshold -Correct Answer ✔-The number of pests or level of damage
at which you should begin treatment to prevent the pest population from
reaching the injury threshold. It is less the injury threshold.
,Successful pest management program includes early -Correct Answer ✔-
detection and diagnosis
Becoming familiar with plants in a greenhouse or interiorscape setting may be
more difficult -Correct Answer ✔-the types of plants grown vary from season to
season to year to year
Inspect and investigate -Correct Answer ✔-watch for unusual spots on foliage,
insects massing underside of leaves, or insect droppings
Step 1. Regular monitoring will help determine if, where, and when treatment is
needed.
Other methods include shaking plants, soil sampling, drenching, and tapping to
detect the presence of insects.
Keeping track of the weather.
Identify the pest and understand pest biology -Correct Answer ✔-Identify what
was found then learn about biology and threshold and control methods of the
pest.
Establish threshold levels -Correct Answer ✔-Consider controlling a particular
pest when you think of economic and unacceptable damage. Vary by setting as
well as by the type of plant
Implement measures to manage pests -Correct Answer ✔-the population of one
organism or species affects various options for pest management. Select the
most appropriate method based on several factors, including the site, aesthetics,
economics, and pest population.
,Cultural methods -Correct Answer ✔-management strategies that make the
environment less suitable for pests, and help prevent problem levels ex.
modifying the site , proper planting, watering, following proper planting
procedures
Biological Control Methods -Correct Answer ✔-uses living organisms, sometimes
called beneficials to reduce or prevent plant damage.
Parasitoids -Correct Answer ✔-insects that lay eggs in or on plant pests and their
immature stages consume the pest.
Biological control methods examples -Correct Answer ✔-learning to distinguish
pests from natural enemies
avoiding the use of long-lasting broad-spectrum pesticides
Providing alternative foods such as flowering and nectar-producing plants.
Chemical Control methods -Correct Answer ✔-Pesticides can be part of a
balanced IPM program. Choose pesticides based on the specific pest involved;
the plant speices affected; the site and impact on humans, nontarget organisms,
and environment.
Restricted use pesticides (RUPs) -Correct Answer ✔-higher risk harming people
and the environment. Must be certified under direct supervision.
General use Pesticides (GUPs) -Correct Answer ✔-available to the public for
purchase and use.
, Integrated pest management (IPM) -Correct Answer ✔-An ecological approach
to pest control uses a mix of cultivation and biological methods, into one
program.
Exoskeleton -Correct Answer ✔-an external skeleton that provides protection
and support
metamorphosis -Correct Answer ✔-change in shape, form, and/or size that an
insect undergoes during its life cycle
Pesticide resistance -Correct Answer ✔-when a pest population is less
susceptible to a pesticide that previously was effective. A population can
develop resistance when the same pesticide is used repeatedly.
Head of insect -Correct Answer ✔-has the mouth parts and some of the sensory
organs.
Mechanical methods -Correct Answer ✔-consist of removing insects or their
pupae such as bagworm bags by hand. screens, traps, barriers or sticky tape.
Biological control -Correct Answer ✔-pit living organisms against each other.
Beneficial insects -Correct Answer ✔-choosing insecticides as a management
option, remember that most of them kill insects as well as pests.
Consider Pesticide resistance -Correct Answer ✔-disrupts a vital function of the
pests and kill it. Insecticides with different modes,
