WYOMING PESTICIDE APPLICATOR
CERTIFICATION. EXAM QUESTIONS
AND ANSWERS 100% PASS.
Pest - ANS An undesirable organism that injures humans, desirable plants and animals,
manufactured products, or natural substances.
Bioaccumulation - ANS The accumulation of a substance, such as a toxic chemical, in fatty
tissues of living organisms.
Biomagnification - ANS The concentration of toxins in an organism as a result of its ingesting
other plants or animals in which the toxins are more widely disbursed.
The four main groups of pests: - ANS 1. Weeds (Undesirable plants)
2. Invertebrates (insects, mites, ticks, spiders, snails, and slugs)
3. Disease agents or pathogens (bacteria, viruses, fungi, nematodes [roundworms],
mycoplasmas [parasitic microorganisms], and other microorganisms)
4. vertebrates (birds, reptiles amphibians, fish, and rodents)
pest management methods - ANS Biological Control, Chemical Control, Cultural Control,
Genetic Control, Mechanical/Physical Control, Regulatory Control
2026 STUDY MATERIAL @COPYRIGHT RESERVED 1
,biological control - ANS The control of a pest by the introduction of natural enemies such as a
predator, parasites, pathogen, or competitor.
chemical control - ANS Use of chemicals , often called pesticides to manage pests.
Hericide - ANS Chemicals used to control weeds
Mode of Action - ANS The way that a chemical kills or stops growth of pests.
Site of Action - ANS The specific biological system affected within the pest
cultural control - ANS practices that reduce pest establishment, reproduction, dispersal, and
survival
Genetic Control - ANS Breeding or selection plants and animals to resist specific pest
problems.
Mechanical/ physical control - ANS Control methods specifically taken to kill the pest directly
or to indirectly make the environment unsuitable for pest entry, dispersal, survival or
reproduction. Examples include deer fences, cloth mesh to exclude birds from fruit trees,
mechanical vertebrate traps, sticky traps for insects
regulatory control - ANS Quarantine of pests or Eradication (elimination) of Pests.
IPM - ANS Integrated Pest Management
integrated pest management - ANS A balanced, tactical approach to est control that uses a
wide range of control methods with a goal of preventing pests from reaching damaging levels
with the least risk to the environment.
2026 STUDY MATERIAL @COPYRIGHT RESERVED 2
,Why practice IPM - ANS Helps keep a balanced ecosystem, pesticides can be ineffective,
saves money, promotes healthy environment, maintains good public image
Key Pests - ANS Pests that will cause major problems unless successfully managed
Secondary pests - ANS become a problem when key pests are controlled or absent.
Occasional pests - ANS require periodic control when environmental influences, there life
cycles, or human activities effect them. EX: Providing then with food, or a strange temperature
surge.
ET - ANS Economic Threshold
EIL - ANS Economic Injury Level
economic threshold - ANS The population level of a pest where action must be taken to keep
the population from exceeding the Economic Injury Level.
Economic Injury Level - ANS The pest population density that causes losses equal to the cost
of control measures.
Components of IPM - ANS 1. Identify the pest and understand its biology
2. Monitor the pest to be managed
3. Develop the pest management goal
4. Implement the IPM program
5. Record and evaluate results
Pesticide Resistance - ANS The ability of a pest to withstand exposure to a given pesticide;
the result of natural selection favoring the survivors of an original population that was exposed
to the pesticide
2026 STUDY MATERIAL @COPYRIGHT RESERVED 3
, FIFRA - ANS Federal Insecticide, Fungicide, and Rodenticide Act
Restricted Use Pesticide - ANS A pesticide that the EPA or a State Regulatory Agency
determines to have the potential to cause unreasonable adverse effects on the environment or
human health, when applied in accordance with its directions for use; requires additional
regulatory restrictions
Unclassified-Use Pesticides - ANS These are pesticides that anyone can use in accordance
with the label. They often have the same ingredients as RUP's but at a much lower toxicity level.
Certified Applicator - ANS A person qualified to apply or supervise the application of
restricted-use pesticides.
Private Applicator - ANS An applicator who uses or supervises the use of any pesticide in the
production of an agricultural commodity.
Commercial Applicator - ANS A certified applicator who uses or supervises the use of
pesticides for purposes other than those covered under a private applicator certification.
Tolerance - ANS The maximum pesticide residue limit that may legally remain on or in treated
crops and animals or animal products sold for food or feed.
The label is... - ANS The LAW!
Worker Protection Standard Regulation - ANS Intended to reduce the incidence of
occupational pesticide exposure and related illnesses and injuries among agricultural workers
and pesticide handlers.
How do pesticide affect the ESA? - ANS The EPA must ensure that no registered pesticide use
is likely to jeopardize the survival of an endangered or threatened species.
