Section One: Questions 1–100
Question 1
Which agency has primary responsibility for registering pesticide products in California before they can be sold
or distributed in the state?
A. Environmental Protection Agency (EPA)
B. Department of Pesticide Regulation (DPR)
C. California Department of Fish and Wildlife
D. United States Department of Agriculture (USDA)
🟢 Correct answer: B
,🔴 RATIONALE: The California Department of Pesticide Regulation (DPR), part of the California Department
of Agriculture, has primary responsibility for registering pesticide products in California. While EPA registers
pesticides at the federal level under FIFRA, California requires additional state registration through DPR before
products can be sold or distributed within the state.
Question 2
A pesticide label states "Restricted Use Pesticide." What does this designation mean?
A. The pesticide can only be used in agricultural settings
B. The pesticide requires a permit from the county agricultural commissioner
C. The pesticide may cause adverse effects to humans or the environment and requires applicator certification
D. The pesticide can only be purchased by licensed pest control companies
🟢 Correct answer: C
🔴 RATIONALE: Restricted Use Pesticides (RUPs) are classified by EPA as pesticides that may cause adverse
effects to humans or the environment even when used according to label directions. RUPs require purchase and
use only by certified applicators or persons under their direct supervision. This classification is based on
toxicity, environmental hazard, or other risk factors, not on setting or purchaser type alone.
Question 3
What is the primary purpose of a Restricted Entry Interval (REI) on a pesticide label?
, A. To ensure the pesticide remains effective for the longest period
B. To prevent human exposure until pesticide residues decrease to safe levels
C. To allow time for the pesticide to fully penetrate the target plant
D. To comply with federal shipping regulations
🟢 Correct answer: B
🔴 RATIONALE: A Restricted Entry Interval (REI) is the time period after pesticide application during which
people are restricted from entering the treated area. The primary purpose is to prevent human exposure until
pesticide residues dissipate to levels considered safe according to toxicological data. REIs are determined based
on the pesticide's toxicity and formulation.
Question 4
Under California law, which of the following must a certified applicator do BEFORE applying a restricted use
pesticide?
A. Notify all neighboring properties within one mile
B. Obtain a permit from the county agricultural commissioner
C. Conduct a soil test to determine pH levels
D. Wait for approval from the EPA
🟢 Correct answer: B
