1. What is the main function of a pesticide label?
Answer: To provide legal instructions for proper use and safety.
Rationale: The pesticide label is a legal document required by the EPA. It
provides directions for safe, effective application, including dosage,
application methods, target pests, and precautions.
2. What does the signal word "Danger" on a pesticide label indicate?
Answer: The pesticide is highly toxic.
Rationale: "Danger" is used for pesticides that pose a severe risk if inhaled,
ingested, or absorbed through skin. It alerts the applicator to extreme
hazards.
3. What is the main goal of integrated pest management (IPM)?
Answer: To use multiple pest control methods to minimize environmental
,impact.
Rationale: IPM combines biological, cultural, mechanical, and chemical
methods to control pests effectively while reducing risks to humans and
the environment.
4. What is the most important step before applying a pesticide?
Answer: Reading and understanding the pesticide label.
Rationale: The label contains critical safety information, proper application
rates, and legal requirements. Ignoring it can result in ineffective
treatment or regulatory violations.
5. How should a pesticide be stored?
Answer: In a cool, dry, locked area away from food and water sources.
Rationale: Proper storage prevents accidental exposure, chemical
degradation, and contamination of food, water, or non-target areas.
6. What is the primary route of pesticide exposure for applicators?
Answer: Skin contact.
Rationale: Dermal exposure is the most common route because pesticides
often come into contact with clothing, gloves, or bare skin during mixing
and application.
7. Why is calibration of pesticide application equipment important?
Answer: To ensure the correct amount of pesticide is applied.
Rationale: Proper calibration prevents over- or under-application, which
can harm non-target organisms or reduce efficacy.
,8. What is the first action if a pesticide is accidentally ingested?
Answer: Contact a poison control center or medical professional
immediately.
Rationale: Rapid response and professional guidance are critical for
minimizing health effects after ingestion.
9. What type of pesticide moves through the plant’s vascular system?
Answer: Systemic pesticide.
Rationale: Systemic pesticides are absorbed and translocated by the plant,
controlling pests that feed on plant tissues.
10. What is the purpose of a pesticide’s active ingredient?
Answer: To control the target pest.
Rationale: The active ingredient is the chemical responsible for killing or
controlling pests, while other ingredients may aid in application or
stability.
11. What does the term "pre-harvest interval" refer to?
Answer: The minimum time between pesticide application and crop harvest.
Rationale: PHI ensures pesticide residues degrade to safe levels before the
crop enters the food chain.
12. Why is it important to avoid pesticide drift?
Answer: To prevent harm to non-target areas and organisms.
Rationale: Drift occurs when pesticides move off-target, potentially
harming plants, animals, water sources, or humans.
, 13. What is the main reason for wearing personal protective equipment
(PPE) during pesticide application?
Answer: To reduce exposure and prevent poisoning.
Rationale: PPE creates a barrier between the applicator and pesticide,
reducing risk from skin, inhalation, or eye contact.
14. How should empty pesticide containers be disposed of?
Answer: Triple-rinse and follow label or local disposal regulations.
Rationale: Proper rinsing removes residues, and following regulations
prevents environmental contamination and legal penalties.
15. What is the term for a pest that develops resistance to a pesticide over
time?
Answer: Resistant pest.
Rationale: Repeated exposure to the same pesticide can select for resistant
individuals, making control less effective.
16. What is the function of an adjuvant in pesticide applications?
Answer: To enhance the effectiveness or handling of the pesticide.
Rationale: Adjuvants may improve spreading, sticking, penetration, or
mixing of pesticides, improving overall efficacy.
17. Which environmental factor most influences pesticide degradation?
Answer: Sunlight.
Rationale: UV radiation from sunlight can break down chemicals
(photodegradation), reducing the pesticide’s effectiveness.
