1. What is the primary purpose of Integrated Pest Management (IPM)?
A) Eliminate all pests using chemical control
B) Replace all pesticides with biological agents
C) Reduce pest populations to economically acceptable levels using
multiple control methods
D) Increase pesticide application frequency
IPM focuses on combining biological, cultural, mechanical, and
chemical methods to manage pests at acceptable economic
thresholds rather than total eradication.
2. Which part of a pesticide label provides legally binding instructions for
use?
A) Marketing section
, B) Safety data sheet only
C) Directions for Use
D) Manufacturer advertisement
The Directions for Use section contains legally enforceable
instructions that must be followed to ensure safe and effective
application.
3. What is the main function of a surfactant in pesticide mixtures?
A) Kill insects directly
B) Increase pesticide toxicity
C) Improve spreading and sticking of spray droplets
D) Neutralize pesticide residue
Surfactants help pesticides spread evenly and adhere to plant
surfaces, improving effectiveness.
4. Which pest management method uses natural predators?
A) Mechanical control
B) Chemical control
C) Cultural control
D) Biological control
Biological control involves using living organisms such as predators,
parasites, or pathogens to suppress pest populations.
5. What is the most common route of pesticide exposure for applicators?
A) Eye absorption
B) Oral ingestion
, C) Dermal (skin) absorption
D) Hair contact
Skin contact is the most frequent exposure route, making protective
clothing essential.
6. What does LD50 represent?
A) Dose needed to kill 50% of plants
B) Legal dosage limit
C) Lethal dose that kills 50% of a test population
D) Lowest detectable dose
LD50 is a standard measure of acute toxicity indicating the dose that
kills half of test animals.
7. Which weather condition increases pesticide drift risk?
A) High humidity
B) Calm wind
C) Strong wind
D) Cool temperature
Wind carries pesticide droplets away from the target area, increasing
drift and environmental contamination.
8. What is the purpose of a pre-harvest interval (PHI)?
A) Increase crop yield
B) Determine fertilizer timing
C) Time between last pesticide application and harvest
D) Control irrigation schedule
, PHI ensures pesticide residues decline to safe levels before crops are
harvested.
9. Which insect life stage undergoes complete metamorphosis?
A) Nymph
B) Larva only
C) Egg, larva, pupa, adult
D) Egg and nymph only
Complete metamorphosis includes four distinct stages, each with
different forms and functions.
10. What is calibration of spray equipment?
A) Cleaning tanks
B) Mixing pesticides
C) Adjusting equipment to apply correct dosage per area
D) Changing pesticide type
Calibration ensures accurate application rates for effective pest
control and environmental safety.
11. Which group of pesticides controls weeds?
A) Insecticides
B) Fungicides
C) Rodenticides
D) Herbicides
Herbicides are specifically formulated to control unwanted plants or
weeds.
