1. Which of the following best describes integrated pest management
(IPM)?
A. Using only chemical pesticides to control pests
B. Eliminating all natural predators to prevent pest spread
C. Combining biological, cultural, physical, and chemical tools to
manage pests economically and ecologically
D. Relying exclusively on genetically modified crops for pest control
Integrated Pest Management (IPM) emphasizes a multi-faceted
approach that reduces reliance on chemicals and promotes
sustainable pest control.
2. What is the primary purpose of a pesticide label?
A. To advertise the pesticide product
B. To provide legal instructions for safe and effective use
C. To list only the chemical composition
D. To provide information about competitor products
Pesticide labels are legally binding and provide detailed instructions
on use, safety precautions, and environmental precautions.
3. Which type of pesticide formulation is most likely to reduce drift
during application?
A. Ultra-low volume (ULV) spray
B. Wettable powder (WP)
C. Aerosol spray
, D. Emulsifiable concentrate (EC)
Wettable powders tend to adhere better to plant surfaces and have
larger droplet sizes, reducing drift compared to ULV or aerosol
sprays.
4. Which class of pesticides is most toxic to humans?
A. Insecticidal soaps
B. Pyrethrins
C. Organophosphates
D. Botanical oils
Organophosphates inhibit acetylcholinesterase in humans and pests,
making them highly toxic if not handled properly.
5. What is the main function of a surfactant in a pesticide mixture?
A. To kill pests directly
B. To neutralize pesticide chemicals
C. To improve the spreading and sticking of pesticide solutions on
target surfaces
D. To increase pesticide volatility
Surfactants reduce surface tension, allowing pesticide solutions to
spread evenly and adhere to plant surfaces, enhancing efficacy.
6. Which of the following is an example of a biological control agent?
A. Glyphosate
B. Lady beetles (Coccinellidae) feeding on aphids
C. Carbaryl
D. Copper sulfate
Biological control agents involve living organisms that naturally
suppress pest populations without chemical intervention.
7. How often should personal protective equipment (PPE) be inspected?
A. Only after chemical spills
B. Once per year
C. Before each pesticide application
D. Only when new PPE is purchased
PPE should be inspected prior to every use to ensure safety and
compliance with label instructions.
8. Which type of pesticide residue is most likely to persist in soil for long
periods?
, A. Rapidly degradable herbicides
B. Microbial pesticides
C. Organochlorine insecticides
D. Botanical insecticides
Organochlorines are chemically stable and resist breakdown, leading
to long-term persistence in soil and potential bioaccumulation.
9. What is the primary reason for calibrating pesticide application
equipment?
A. To reduce equipment wear
B. To ensure the correct pesticide rate is applied uniformly
C. To comply with marketing standards
D. To minimize fuel consumption
Calibration ensures the correct amount of pesticide reaches the
target, preventing under- or over-application.
10. Which environmental factor most affects pesticide volatility?
A. Soil pH
B. Temperature
C. Rainfall only
D. Wind direction
Higher temperatures increase the evaporation rate of volatile
pesticides, potentially reducing efficacy and increasing off-target
movement.
11. Which of the following is a systemic pesticide?
A. Dust formulations applied to leaf surfaces
B. Contact sprays that remain on foliage
C. Imidacloprid absorbed by roots and transported throughout the
plant
D. Granular pesticides applied to soil surface only
Systemic pesticides are absorbed by plants and move within tissues,
providing protection against pests that feed on various plant parts.
12. The concept of “economic threshold” refers to:
A. The cost of pesticides per acre
B. The pest population level at which control measures should be
applied to prevent economic loss
C. The minimum crop yield acceptable
