PA Pesticide Applicator Exam Core Info with correct
answers 2024-2025GRADED A
Bioaccumulation - Correct answer-The accumulation of a substance, such as a toxic chemical, in various
tissues of a living organism.
Biomagnification - Correct answer-Accumulation of pollutants at successive levels of the food chain
abiotic factors - Correct answer-natural control measures within the environment.
EX: climactic factors, air/water pollution, topographic features.
Biological Control - Correct answer-The use of natural enemies to control pests.
EX: Predators, Parasites, Pathogens
Cultural Control - Correct answer-These are Practices that reduce pest establishment, reproduction,
dispersal and survival.
EX: Mowing, irrigation, aeration, fertilization and sanitation.
Genetic control - Correct answer-Making use of plant varieties that are naturally resistant to insect
feedings.
,What are some of the ways to control Spring dead spot? - Correct answer-1.) In areas prone to harsh
winters, select less susceptible cultivars. Bermuda grass cultivars with good cold tolerance also tend to
be more resistant to spring dead spot
2.) Aerify and dethatch regularly
3.) Stop nitrogen applications to bermuda grass 6 weeks prior to the expected rate of dormancy
4.) Use fertilizer such as ammonium sulfate
What is a Host? - Correct answer-Organism that is invaded by a plant parasite, which obtains its
nutrients, and reproduces upon it
What is a Sign? - Correct answer-Visible pathogen or its parts or products on a host plant
What are Bactericides? - Correct answer-Chemicals that are used for control of bacterial diseases
Mechanical/Physical control - Correct answer-Kills a pest directly or makes its environment unsuitable
EX: Rodent traps, deer fences, mulches, barriers
Regulatory control - Correct answer-Removal of pests that cant be controlled at a local level. Utilizes
quarantines to prevent entry of pests at airports or ocean ports and can be used to remove pests with
government power. (i.e. draining standing water that provides breeding sites for mosquitos.)
Mode of action - Correct answer-How chemicals kill a pest
Site of action - Correct answer-The specific biological system affected within the pest
Economic threshold - Correct answer-The point at which the economic loss caused by pest damage
outweighs the cost of applying a pesticide.
(Treat pests when they pass the economic threshold)
Economic injury level - Correct answer-the pest population density that causes losses equal to the cost
of control measures
, Action threshold - Correct answer-the predetermined level at which pest control is needed
Certified applicator - Correct answer-A person qualified to apply or supervise the application of
restricted-use pesticides.
Private applicator - Correct answer-A certified applicator who uses or supervises the use of any
restricted-use pesticide to produce an agricultural commodity.
Commercial applicator - Correct answer-A certified applicator who uses or supervises the use of
pesticides for purposes other than those covered under a private applicator certification.
Food Quality Protection Act (FQPA) - Correct answer-set pesticide limits in food, & all active and inactive
ingredients must be screened for estrogenic/endocrine effects. (Amended FIFRA) Review old pesticides
and aggregate/cumulative exposure.
Federal Food, Drug, and Cosmetic Act (FFDCA) - Correct answer-A set of laws passed by Congress giving
authority to the Food and Drug Administration (FDA) to oversee the safety of food, drugs, and
cosmetics. Also called for the reassessment of existing tolerances. Governs the establishment of
pesticide tolerances for food and feed.
Worker Protection Standard - Correct answer-is intended to reduce the incidence of occupational
pesticide exposure and related illnesses/injuries. Employers must supply pesticide safety training, ppe,
and decontamination supplies as well as maintain records and display specific pesticide safety
information.
Under federal law is it unlawful (and will you be subject to criminal/civil penalties) to detach, alter,
deface or destroy any part of a container or labeling. - Correct answer-yuh
