GUIDE | EXAM PREP | PRACTICE TEST | CERTIFICATION
PREPARATION
1. A commercial pesticide applicator in California is preparing to apply a restricted-use
pesticide. What should the applicator do before beginning the application?
A. Apply the pesticide immediately if the label appears familiar
B. Increase the application rate to improve effectiveness
C. Read and follow all pesticide label directions and restrictions
D. Mix the pesticide with additional products without approval
The pesticide label is a legal document that provides required instructions for use, including
application rates, safety requirements, and restrictions. Applicators must follow label
directions to remain compliant and protect people and the environment.
2. The primary purpose of pesticide regulations in California is to:
A. Increase pesticide sales
B. Eliminate all pest populations permanently
C. Protect public health, agricultural resources, and the environment
D. Reduce the need for applicator training
Pesticide regulations are designed to ensure pesticides are used safely and effectively while
minimizing risks to humans, animals, and the environment.
3. A pesticide applicator notices that wind speed has increased significantly during an
application. What is the most appropriate action?
A. Continue spraying at the same rate
B. Increase pressure to compensate
C. Stop or adjust the application to prevent drift
D. Apply closer to sensitive areas
,Wind conditions can cause pesticide drift, which may expose unintended areas and organisms.
Applicators must monitor conditions and adjust operations to prevent off-target movement.
4. Which document provides legally required information about pesticide use?
A. Equipment manual
B. Sales brochure
C. Pesticide label
D. Applicator advertisement
The pesticide label contains legally enforceable instructions regarding application, safety,
storage, and disposal. Applicators must comply with label requirements.
5. Personal protective equipment (PPE) is required because it:
A. Improves pesticide effectiveness
B. Reduces application time
C. Reduces applicator exposure to hazardous pesticides
D. Eliminates the need for training
PPE protects applicators from pesticide exposure through skin contact, inhalation, and other
routes. Proper selection and use are essential for safety.
6. A pesticide applicator accidentally spills concentrated pesticide. What should be done
first?
A. Wash the spill into a drain
B. Ignore the spill if it is small
C. Follow emergency procedures and contain the spill safely
D. Cover it with soil and leave the area
Pesticide spills require immediate response to prevent environmental contamination and

restrictions designed to prevent contamination.
9. The active ingredient in a pesticide is the component that:
A. Provides packaging protection
B. Controls the pest
C. Provides the pesticidal effect
D. Improves equipment performance
The active ingredient is the chemical component responsible for controlling the target pest.
Other ingredients support product use and application.
10. A pesticide applicator should calibrate equipment to:
A. Increase pesticide waste
B. Avoid reading labels
C. Apply the correct amount of pesticide accurately
D. Eliminate maintenance
