What is the significance of the "signal word" on a pesticide label?
✔✔The signal word indicates the toxicity level of the pesticide and helps applicators understand
the risks associated with its use.
How should you dispose of unused pesticides or pesticide containers?
✔✔Follow local regulations and dispose of them at a certified hazardous waste disposal site to
prevent environmental contamination.
What are the risks of pesticide drift, and how can they be minimized?
✔✔Pesticide drift can cause contamination of nearby areas, harm non-target organisms, and
violate regulations. It can be minimized by applying pesticides during calm weather and using
appropriate nozzles.
Why is pesticide application equipment calibration essential?
1
,✔✔Calibration ensures the correct amount of pesticide is applied to the target area, preventing
over- or under-application and minimizing waste.
What are some common symptoms of pesticide poisoning?
✔✔Symptoms can include dizziness, headaches, nausea, sweating, or difficulty breathing,
depending on the pesticide’s toxicity.
How do you protect water sources from pesticide contamination?
✔✔Avoid applying pesticides near water sources, use proper equipment to prevent leaks, and
follow best practices to prevent runoff.
What is the difference between a "restricted-use pesticide" and a general-use pesticide?
✔✔A restricted-use pesticide can only be applied by certified applicators due to its higher
toxicity or environmental impact. A general-use pesticide is safer and can be applied by
unlicensed individuals.
Why is it important to store pesticides in their original containers?
✔✔Storing pesticides in their original containers ensures proper identification, retains safety
instructions, and prevents accidental misuse.
2
,What should you do if a pesticide spill occurs?
✔✔Immediately contain the spill, wear proper PPE, and follow the label’s emergency
procedures for cleanup and disposal.
Why must pesticide application records be maintained?
✔✔To comply with legal requirements, track pesticide use, and provide documentation in case
of an investigation or audit.
How can pesticide applicators reduce the risk of contamination when mixing pesticides?
✔✔Mix pesticides in a designated area, use clean equipment, and follow the manufacturer’s
mixing instructions carefully.
Why is it necessary to keep a pesticide application log?
✔✔To document the amount, location, and timing of pesticide use, which is required by law and
helps with safety monitoring.
What does the term "pesticide resistance" mean?
3
, ✔✔Pesticide resistance occurs when pests evolve to become less susceptible to a particular
pesticide, often due to overuse of the same product.
How should you handle pesticide containers after use?
✔✔Triple-rinse the containers to remove any residue, and dispose of them according to local
regulations.
What is the best way to avoid pesticide contamination during transportation?
✔✔Ensure containers are securely sealed, transported upright, and kept in a well-ventilated area
away from food or water sources.
How do you know if a pesticide is safe for use in a specific area?
✔✔Check the pesticide label for site-specific instructions to ensure it is approved for use on the
target crop or area.
Why is it important to follow the pre-harvest interval (PHI) on pesticide labels?
✔✔The PHI ensures that pesticide residues do not exceed safe levels on harvested crops or food,
preventing potential health risks.
