Pesticide Safety (Core)
Pesticide safety is the cornerstone of responsible pest management. This section covers the fundamental principles of safe pesticide handling, including personal protective equipment (PPE), first aid procedures for exposure, toxicity categories (signal words: DANGER, WARNING, CAUTION), and the routes of exposure â oral, dermal, inhalation, and ocular. These concepts appear frequently on state applicator exams.

Review these sample questions before starting the practice test.
Q1: What is the primary purpose of the EPA registration number on a pesticide label?
- A. To indicate the retail price
- B. To uniquely identify the product and confirm EPA registration â
- C. To show the manufacturing date
- D. To indicate the toxicity category
The EPA registration number uniquely identifies each pesticide product and confirms it has been reviewed and registered by the EPA. This number is required on every pesticide label sold in the United States.
Q2: Which type of pesticide is classified as "restricted use"?
- A. Any pesticide sold in a retail store
- B. Pesticides that may cause unreasonable adverse effects even when used as directed â
- C. All organic pesticides
- D. Pesticides that are water-soluble
Restricted Use Pesticides (RUPs) are products that may cause unreasonable adverse effects to the environment or injury to applicators, even when used according to label directions. They can only be purchased and applied by certified applicators.
Q3: What does the term "formulation" refer to in pesticide terminology?
- A. The method of applying the pesticide
- B. The way the active ingredient is mixed with inert ingredients for practical use â
- C. The chemical name of the pesticide
- D. The target pest species
A formulation is the mixture of active ingredient(s) with inert (other) ingredients to create a product that can be effectively and safely applied. Common formulations include emulsifiable concentrates (EC), wettable powders (WP), and granulars (G).
Q4: When mixing pesticides, what should you do FIRST?
- A. Pour the concentrate into the tank
- B. Read the entire product label â
- C. Put on your work boots
- D. Fill the tank with water
Before handling any pesticide, you must always read the entire label first. The label contains critical information about mixing rates, PPE requirements, safety precautions, and first aid measures. Reading the label is the law.
Q5: Which of the following is considered an "inert" ingredient?
- A. The active chemical that kills the pest
- B. Any ingredient in the product that does not directly control the target pest â
- C. The EPA registration number
- D. The signal word on the label
Inert (or "other") ingredients are components that do not directly act against the target pest. They serve other purposes such as solvents, carriers, emulsifiers, or preservatives. Despite being called "inert," some may still pose health or environmental risks.
Q6: What is the proper way to dispose of excess pesticide spray mixture?
- A. Pour it down a storm drain
- B. Apply it to a labeled site at label rates â
- C. Dump it in an open field
- D. Pour it into a stream to dilute it
The best way to dispose of excess spray mixture is to apply it to a labeled site at labeled rates. This ensures the product is used according to its registration and does not contaminate water sources or non-target areas.
Q7: What does "general use pesticide" mean?
- A. It can only be used by commercial applicators
- B. It can be purchased and used by the general public when used according to label directions â
- C. It works on all types of pests
- D. It requires a special license to purchase
General use pesticides are products that will not cause unreasonable adverse effects when used according to label directions. They are available for purchase and use by the general public without certification requirements.
Q8: Which factor is MOST important when selecting a pesticide for a specific pest problem?
- A. The color of the product label
- B. The pest identified and the site where it will be applied â
- C. The size of the container
- D. Whether it is on sale
Proper pest identification and site assessment are the most critical factors in pesticide selection. The product must be labeled for both the target pest and the application site. Using a pesticide on a site not listed on the label is a federal violation.
