TENNESSEE PESTICIDE APPLICATOR
COMPREHENSIVE ANSWERS AND QUESTIONS SURE
A+
✔✔What is the primary mechanism of pyrethroid poisoning? - ✔✔Acts on sodium
channels.
✔✔What should be done if a pesticide is ingested? - ✔✔Read the label's first-aid
statement FIRST; call Poison Control or a physician immediately.
✔✔What is the minimum PPE required for Category II inhalation exposure? -
✔✔Respirator required.
✔✔What is dermal sensitization? - ✔✔A product either is or isn't a sensitizer, tracked
separately from toxicity categories.
✔✔What is the risk associated with temperature inversions during pesticide application?
- ✔✔They trap fine droplets in stable air, allowing them to drift unpredictably.
✔✔What type of drift is caused by the physical movement of spray droplets? -
✔✔Particle (droplet) drift.
✔✔What is the first aid action for eye exposure to pesticides? - ✔✔Hold eyelid open,
flush with clean running water for 15 minutes minimum, get medical attention.
✔✔What is the difference in cholinesterase inhibition between carbamates and
organophosphates? - ✔✔Carbamates bind reversibly; organophosphates bind
irreversibly.
✔✔What is the minimum PPE for Category III eye exposure? - ✔✔Protective eyewear
required.
, ✔✔How should contaminated clothing be laundered? - ✔✔Wash separately from
household laundry, use hot water/heavy-duty detergent, and line-dry when possible.
✔✔What are the symptoms of nicotinic poisoning? - ✔✔Muscle twitching/weakness, fast
heart rate, sweating, and sometimes dilated pupils.
✔✔What is the action for skin exposure to a corrosive pesticide? - ✔✔Remove
contaminated clothing and wash skin immediately.
✔✔What is the LD50 for Category IV toxicity? - ✔✔> 5,000 mg/kg
✔✔What is the significance of a pesticide's signal word? - ✔✔It indicates the highest
toxicity category based on the worst route/effect.
✔✔What is the inhalation LC50 for Category I? - ✔✔≤ 0.2 mg/L
✔✔What is the solubility of pesticides in water? - ✔✔Pesticides dissolve readily in
water.
✔✔What does low adsorption (Koc) indicate about a pesticide? - ✔✔The pesticide
doesn't bind to soil and stays dissolved.
✔✔What is the persistence/half-life of a pesticide? - ✔✔It is long, allowing more time to
leach before breaking down.
✔✔How does soil texture affect pesticide movement? - ✔✔Sandy or coarse soil has
larger pores, leading to faster water movement.
✔✔What is the impact of a shallow depth to the water table on pesticide use? -
✔✔There is less soil to filter or degrade the pesticide.
✔✔What timing of rainfall or irrigation can exacerbate pesticide runoff? - ✔✔Heavy
watering soon after application.
✔✔What conditions worsen pesticide runoff? - ✔✔Slope, compaction, and heavy rain.
✔✔What must applicators check within 6 months of pesticide application? -
✔✔Endangered Species Protection Bulletins via EPA's Bulletins Live! Two.
✔✔What is phytotoxicity? - ✔✔Injury to non-target plants from drift, misapplication, or
plant sensitivity.
✔✔What are the Three C's of spill response? - ✔✔Control, Contain, Clean up.
