WASHINGTON PESTICIDE LAWS LATEST 2026 TESTS
PAPER 1 QUESTIONS AND SOLUTIONS GUARANTEE A+
✔✔organophosphate - ✔✔a large group of pesticides that contain the element
phosphorus. Most are non persistent insecticides/miticides
EX malathion, parathion, and diazinon
✔✔carbamates - ✔✔a group of pesticides containing nitrogen, formulated as
insecticides, fungicides, and herbicides
✔✔topical acute effects - ✔✔a result of either the irritant properties of a chemical in a
pesticide formulation or an allergic response by the victim
✔✔atropine sulfate - ✔✔Antidote for carbamates and organophosphates
✔✔False - ✔✔The hazard associated with a pesticide product depends entirely on the
toxicity of the active ingredient.
✔✔False - ✔✔The common route of pesticide exposure leading to poisoning is
inhalation
✔✔Chronic toxicity - ✔✔toxicity from small, repeated exposures to a pesticide over a
period of time is called
✔✔False - ✔✔Under the Worker Protection Standard, a farm laborer who hand picks
vegetables is considered a handler, not a worker.
✔✔OSHA - ✔✔Occupational Safety and Health Administration
✔✔True - ✔✔Pesticide respirators should be approved by:
National Institute for Occupational Safety and Health
and
Mine and Safety Health Administration
✔✔False - ✔✔Never use your waste rinsewater as a diluent for future applications
✔✔True - ✔✔Applications records must be kept for 7 years
✔✔Drift - ✔✔the airborne movement of pesticide spray droplets, dusts, or vapors
beyond the intended contact area
✔✔Temperature Inversion - ✔✔when air at ground level is cooler than the air above it,
and there is little or no vertical air movement
, ✔✔volatilization - ✔✔the change of a substance from a liquid or solid state to a gas at
ordinary temperatures when exposed to air
✔✔Adsorption - ✔✔the process by which chemicals are held or bound to a surface by a
physical or chemical attraction. Clay and high organic soils tend to adsorb pesticides
✔✔Absorption - ✔✔The movement of a chemical into plants, animals, microorganisms,
or soil
✔✔Runoff - ✔✔the movement of water and associated materials on the soil surface
✔✔leaching - ✔✔the movement of a substance through soil with water
✔✔plant removal - ✔✔the final pesticide transfer process after treated crops are
harvested and transferred to a new location
✔✔Microbial degradation - ✔✔breakdown of a chemical by microorganisms
✔✔Chemical degradation - ✔✔the breakdown of a pesticide by processes not involving
a living organism
✔✔photodegradation - ✔✔breakdown of chemicals by the action of sunlight
✔✔Phytotoxic - ✔✔injury to plants
✔✔False - ✔✔the airborne movement of a pesticide from its target area occurs only
during application and is clearly visible when it occurs.
✔✔True - ✔✔Incorporation could help reduce pesticide volatilization
✔✔False - ✔✔Pesticide adsorption is greatest in coarse, sandy soils.
✔✔True - ✔✔Runoff is usually more likely from a water-saturated soil than from an
unsaturated soil.
✔✔True - ✔✔Pesticide degradation processes can be beneficial because they reduce
the amount of pesticide residue in the environment.
✔✔False - ✔✔Pesticide properties have little if any effect on whether a chemical will
reach groundwater
✔✔True - ✔✔Pesticide-contaminated surface water can contaminate groundwater
