1. A pesticide label states “Restricted Entry Interval (REI): 12 hours.” What does this mean
for workers?
A. Workers may re-enter only after 12 hours without PPE
B. Workers may enter only for emergency rescue during 12 hours
C. Workers may apply pesticide again after 12 hours
D. Workers must wait 12 hours before transporting product
════════════════════
Correct Answer: B. Workers may enter only for emergency rescue during 12 hours
The REI is the time immediately after pesticide application during which entry into the
treated area is restricted, except for trained and protected workers performing
,emergency tasks. Options A, C, and D misinterpret REI as a reapplication or transport
restriction rather than an entry safety restriction.
2. Which practice best reduces pesticide drift during spraying?
A. Increasing spray pressure
B. Using fine droplet nozzles
C. Spraying during high wind
D. Lowering boom height and using coarse droplets
════════════════════
Correct Answer: D. Lowering boom height and using coarse droplets
Drift is minimized by reducing droplet size variability and keeping spray close to target.
Coarse droplets and low boom height reduce off-target movement. Fine droplets and
high wind increase drift risk.
3. What is the primary purpose of Integrated Pest Management (IPM)?
A. Eliminate all pests using chemical pesticides
B. Prevent pest resistance through chemical rotation only
C. Combine methods to manage pests economically and environmentally
D. Replace all biological controls with synthetic pesticides
,════════════════════
Correct Answer: C. Combine methods to manage pests economically and
environmentally
IPM integrates biological, cultural, mechanical, and chemical controls to reduce reliance
on pesticides. It does not aim for total pest elimination or exclusive chemical use.
4. A pesticide label is considered a legal document because it:
A. Is approved by retailers
B. Contains manufacturer advertising claims
C. Provides enforceable use directions by law
D. Can be modified by applicators in the field
════════════════════
Correct Answer: C. Provides enforceable use directions by law
The label is legally binding; using a pesticide contrary to label instructions is a violation
of federal and state law. Applicators cannot modify label directions.
5. Which condition most increases pesticide volatility?
A. Low temperature and high humidity
, B. High temperature and low humidity
C. Low wind and cloudy skies
D. High soil moisture and cool weather
════════════════════
Correct Answer: B. High temperature and low humidity
Volatility increases when pesticides evaporate easily, which is promoted by heat and dry
air conditions.
6. What is the first action if a pesticide spill occurs in the field?
A. Notify the media
B. Apply more pesticide to dilute it
C. Contain the spill and prevent spread
D. Wash equipment immediately in irrigation canal
════════════════════
Correct Answer: C. Contain the spill and prevent spread
Immediate containment prevents environmental contamination and exposure. Reporting
and cleanup follow containment.
