Utah Pesticide Applicator Exam – 2025 – Questions and Answers
Term - -Definition
-Biomagnification - -some organisms accumulate chemical residues in higher
concentrations than those found in the organisms they consume
-Food chain - -sequence of amimals feeding in a natural environment
-Non-living agents - -some plants are damaged by weather extremes, salts, air polutants,
and inadequate or excessive fertilization
-Pest host - -animal or plant on which the organism lives
-Natural controls - -measures that destroy pests without dependance on humans for
continued success (climate, wind, heat, rain)
-Applied controls - -biological, mechanical, cultual, physical, genetic, chamical, and
regulatory
-Biological control - -involves locating the native home of the pest and introducing a
suitible natural enemy into the system. Can be one of the most economic means of control.
-Mechanical control - -use of devices, machines, or other physical methods to control pests
or alter their environment
-Cultural control - -alter the condition of the host plant/site, environment, or pest
behavior to prevent or supress an infestation
-Physical modification - -altering the light, humidity, temperature, etc. of the pests
environment
-Host resistance / genetic control - -genetic modoification = host resistant species
-Chemical control - -pesticifes that are naturally derived or synthesised
-Pesticide - -any material applied to soil, plants, water, cropsm structures, clothing or
animals to kill, attract, repel, or interrupt the growth and mating of pests, or to regulate
plant growth
-Mode of action - -denotes what specific system in the pest is affected by the pesticide
-Systemics - -absorbed through leaves or roots and transported within the plant
-Contact pesticides - -not absorbed and must come in direct contact with the target peat
, -Residual pesticides - -control pests for weeks, months, years
-Regulatory control - -for problems that involve pests that pose a serious danger to public
health or are likely to cause widespread damage to crops or animals
-Quarantine - -process designed to prevent entry of pests into pest free areas
-Eradication - -eliminate a pest from a designated area
-IPM - -balanced tactical approach to pest control - limited reliance on pesticides -
minimize damage with least risk to environment
-IPM Components - -(1) ID pest and understand biology, (2) monitor the pest to be
managed (3) develop pest management goal (eradication, supression, prevention), (4)
implement IPM management program, (5) record and evaluate results
-Key pests - -may cause regular damage unless controlled (e.g., weeds)
-Occasional pests - -cause problems only periodically, usually based on lifecycle and
environmental factors (e.g., ants)
-Secondary pests - -become pronlematic after another pest is controlled and a niche is
exposed
-Economic threshold - -pest population density at which control is required to prevent
economic injury level
-Econimic injuy level - -pest population densith causes losses equal to the cost of control
measures
-Action threshold - -pest level at which management action must be taken
-Pesticide resistance - -ability or insect, fungas, rodent, weed, or pest to tolerate a
pesticide that once controlled it
-FIFRA - -enacted in 1947, ammended in 1972, 75, 78, 88. Federal law regulating pesticide
use
-Unclassified use - -lower toxicity than restricted use and less potential to harm humans or
the environment - most "would be" general use pesticides are unclassified
-Private applicator - -using chemical on property that you own rent or lease
-Commercial applicator - -use restricted use pesticide on property exempt from those
defined under the private applicator definition
