OREGON PESTICIDE LAWS AND SAFETY EXAM
QUESTIONS AND ANSWERS UPDATED (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 | | | | | | | | |
