OREGON PESTICIDE LAWS AND SAFETY EXAM
QUESTIONS AND ANSWERS UPDATED
(2024/2025) (VERIFIED ANSWERS)
Pesticide drift - ANS ✓the unintentional diffusion of pesticides and the potential
negative effects of pesticide application—including: off-target contamination due
to spray drift as well as runoff from plants/soil.
Particle Drift - ANS ✓small liquid/dust droplets or particles are easiest to move
away from targeted area. USE largest droplet size that gives best pest control as
label allows.
Vapor Drift - ANS ✓vapor containing the pesticide active ingredient moves off
the application site. usually through evaporation
How to avoid drift? - ANS ✓check weather conditions, equipment; larger
droplet size (pressure- higher the smaller droplet size),
chemical formulation (less volatile- amine instead of esters)
Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) - ANS ✓allows
EPA to monitor/ regulate all pesticides usage/distribution. Registration,
approval/use from label, determines general use or Restricted use, enforce law
Federal Food, Drug and Cosmetic Act (FFDCA) - ANS ✓EPA set pesticide
tolerances for all pesticides used in or on food or in a manner that will result in a
residue in or on food or animal feed. FDA enforces it. A tolerance is the maximum
permissible level for pesticide residues allowed in or on human food and animal
feed.

Occupational Safety and Health Administration (OSHA) - ANS ✓protects
people in the workplace. requires employer to keep safety/injury/death records
and report them. employee has the right to know about pesticide use/ REI/health
issues
Endangered Species Act (ESA) - ANS ✓requires federal agencies to ensure that
any action they authorize, fund, or carry out, will not likely jeopardize the
continued existence of any listed species, or destroy or adversely modify any
critical habitat for those species.
Restricted entry interval REI - ANS ✓All WPS qualified pesticides have labels
which indicate when it is safe to enter the area after its application. Workers may
not enter the area without special preperation
Hazard communication standard HCS - ANS ✓requires employers to train
their employees to recognize chemical hazards - using the information provided
on product labels and in safety data sheets - and to take the necessary
precautions to protect themselves.
Section 3 - ANS ✓ORS 634Oregon Revised statutes- State Pesticide Control: must
be registered with ODA after EPA registers them
Section 24(c) - ANS ✓Special local needs. If a pest causes serious damage to a
crop and there is no pesticide already registered to control it. FIFRA allows states
to give out. must have the supplemental label when applying
Personal protective equipment (PPE) - ANS ✓special clothing or equipment
that protcts from pesticide exposure. coveralls, protective suits, gloves aprons,
respirators eye ware etc must .
Exposure - ANS ✓how much chemical contacted the body surface
Dose - ANS ✓the amount of chemical absorbed into the body (through skin, eye,
gut, lung)
