feeding on treated plants.
11. Which of the following is a common environmental concern associated with pesticides?
A) Soil enrichment
B) Water contamination
C) Increase in pollinators
D) Plant growth stimulation
*Answer: B – Pesticides can leach or run off into water, potentially harming aquatic life and
water quality.
12. Which type of pesticide formulation reduces drift during application?
A) Ultra-low volume (ULV) sprays
B) Granules or wettable powders
C) Fumigants
D) Foggers
*Answer: B – Granules and wettable powders are less prone to drift than fine sprays or
fumigants.
13. What does the signal word “Danger” indicate on a pesticide label?
A) Low toxicity
B) Moderate toxicity
C) High toxicity
D) Only dangerous if ingested
*Answer: C – “Danger” signifies the highest level of acute toxicity, requiring strict handling
precautions.
14. Which factor has the greatest influence on pesticide volatility?
A) Color of the product
B) Temperature and formulation type
C) Label font size
D) Application equipment brand
*Answer: B – Higher temperatures and certain formulations increase the likelihood that the
pesticide will vaporize and move off target.
15. The main goal of a pre-application site assessment is to:
A) Determine the cheapest pesticide
B) Identify pest presence and potential hazards
, C) Skip safety measures
D) Measure the label font
*Answer: B – Assessing the site helps determine the proper pesticide, timing, and precautions to
minimize risks.
