1. The primary purpose of integrated pest management (IPM) in
agricultural production is to:
A. Eliminate all pests from a crop permanently
B. Apply pesticides on a routine calendar schedule
C. Manage pest populations while minimizing economic,
environmental, and health risks
D. Replace all chemical controls with biological controls
Rationale: IPM focuses on using multiple pest management strategies,
including monitoring, cultural practices, biological controls, and
pesticides when necessary. The goal is not complete pest elimination
but maintaining pests below economically damaging levels.
2. The economic threshold in pest management refers to the:
,A. Point where all pests must be destroyed
B. Pest population level at which control action should be taken to
prevent economic loss
C. Maximum pesticide application rate allowed
D. Number of pesticide applications required per season
Rationale: The economic threshold helps applicators determine when
pest control measures are justified. Treating before this point may
waste resources, while treating after major damage occurs may reduce
crop value.
3. Which organization regulates pesticide use and registration in the
United States?
A. USDA only
B. OSHA
C. FDA
D. Environmental Protection Agency (EPA)
Rationale: The EPA registers pesticides and establishes requirements for
their use under federal pesticide laws, including labeling requirements
and safety standards.
,4. The pesticide label is considered:
A. A suggestion for pesticide application
B. Optional guidance for experienced applicators
C. A legally enforceable document that must be followed
D. A marketing document created by manufacturers
Rationale: Federal law requires pesticide users to follow label directions.
Using a pesticide inconsistently with the label can result in violations
and penalties.
5. A restricted-use pesticide (RUP) may only be applied by:
A. Any homeowner
B. Anyone who purchases the product
C. Certified applicators or persons under their direct supervision as
allowed by regulations
D. Agricultural workers without training
Rationale: Restricted-use pesticides have greater potential risks and
require certified applicator involvement to ensure proper handling and
application.
6. Which factor most directly affects pesticide drift?
, A. Soil color
B. Crop variety
C. Wind speed and direction
D. Fertilizer type
Rationale: Wind can carry pesticide droplets away from the target area.
Applicators must monitor wind conditions and adjust applications to
reduce drift.
7. Calibration of agricultural application equipment is necessary to:
A. Increase pesticide toxicity
B. Ensure the correct amount of pesticide is applied uniformly
C. Eliminate the need for labels
D. Reduce crop growth
Rationale: Proper calibration ensures accurate application rates,
preventing under-application, over-application, crop injury, and
environmental contamination.
8. Which formulation usually contains pesticide particles suspended in
water?
