IDAHO PESTICIDE APPLICATOR EXAM 2023-2024 ACTUAL EXAM 180 QUESTIONS AND CORRECT DETAILED
ANSWERS
FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act) - (answer) Regulates production, transport,
sale, use, and disposal of pesticides
FIFRA Section 3 - (answer) Full federal registration
FIFRA section 24c - (answer) Special local need (application site or alternate control technique not on
label)
FIFRA Section 18 - (answer) Emergency exemption (pest with no current control)
the federal worker protection standard - (answer) Reduce risk of employee exposure to pesticides
Clean Water Act - (answer) (CWA, 1972) set maximum permissible amounts of water pollutants that
can be discharged into waterways; aims to make surface waters swimmable and fishable
Pesticide Hazard - (answer) Risk = toxicity x exposure
Phytotoxicity - (answer) Injury or damage to a sensitive plant caused by a chemical exposure
Adjuvant - (answer) Product added to spray tank to assist pesticide in application
Emulsifiable Concentrate (EC) - (answer) A pesticide formulation produced by mixing an active
ingredient and an emulsifying agent in a suitable petroleum solvent. When combined with water, a milky
emulsion is usually formed. Easy to handle and easy on equipment.
Flowables (F or AF) - (answer) Insoluble solid active ingredients ground and mixed with liquid. Forms a
suspension (slurry) when ready to use. Requires agitation and leaves residue.
Solutions (S) - (answer) AI dissolved in liquid carrier. Does not settle when mixed with water.

ANSWERS
Ready-to-Use (RTU) low concentrate solutions - (answer) Do not require further dilution before
application. Consist of small amount of active ingredient (often 1% or less per unit volume). Expensive.
Ultra Low Volume (ULV) - (answer) Have almost 100% active ingredient, used as is, or diluted only a
little bit. Applied as very fine droplets (high drift potential). Requires specialized equipment.
Aerosols (A) - (answer) Fine liquid droplets with small amounts of AI. Some are ready to use (bug
spray). High drift and inhalation potential.
Dry Formulations - (answer) Dry material suspended in water. High percentage of AI measured by
weight. Require constant agitation.
Dusts and Granules - (answer) Ready to use, reach hard to get places. Very little AI.
Baits - (answer) An active ingredient mixes with an edible substance or some other attractant. Low AI
percentage (less than 5%).
Granules and Pellets - (answer) Dry, ready-to-use materials usually containing from 2-15% active
ingredient. Most granules are prepared by applying the active ingredient as a liquid to a coarse, porous,
solid. Granular formulations are applied to the soil where the active ingredient can then be absorbed by
the roots and trans-located through the plant. Relatively low AI.
Microencapsulation - (answer) Liquid or dry pesticide coated in latex. Breaks down with water. High
hazard to bees.
Fumigants - (answer) Small molecules which are delivered as a gas to penetrate soil or other materials.
Must be used in closed spaces and soils. Most hazardous of all formulations.
Recharge - (answer) Water that seeps through soil
