CPA Pesticide Label Comprehension 3 — Questions and Answers
Question 1: What is the purpose of the EPA Registration Number found on a pesticide label?
- It identifies the batch number for quality control
- It confirms the product is registered with the EPA and approved for sale in the US (Correct answer)
- It indicates the product's toxicity category
- It specifies the expiration date of the product
Correct answer: It confirms the product is registered with the EPA and approved for sale in the US
The EPA Registration Number uniquely identifies an EPA-approved pesticide product and confirms its legal registration for sale.
Question 2: A pesticide label reads 'Do not apply within 100 feet of water.' Which label section typically contains this restriction?
- Directions for use
- Environmental hazards (Correct answer)
- First aid
- Storage and disposal
Correct answer: Environmental hazards
Buffer zone restrictions near water bodies are found in the Environmental Hazards section of the label.
Question 3: When a pesticide label lists 'chemically resistant gloves' as required PPE, what does this mean?
- Any household rubber gloves are acceptable
- Gloves must be made of a material impermeable to the specific pesticide formulation (Correct answer)
- Gloves are optional if exposure is brief
- Only glove liners are required under outer work gloves
Correct answer: Gloves must be made of a material impermeable to the specific pesticide formulation
Chemically resistant gloves must be made of materials (e.g., nitrile, neoprene, or butyl rubber) that resist permeation by the specific pesticide being handled.
Question 4: What does 'REI: 24 hours' mean on a pesticide label?
- Reapply the pesticide every 24 hours
- Workers must not enter treated areas for 24 hours without appropriate PPE (Correct answer)
- The product expires 24 hours after mixing
- The product must be stored for 24 hours before use
Correct answer: Workers must not enter treated areas for 24 hours without appropriate PPE
The Restricted Entry Interval (REI) is the time workers must stay out of treated areas or wear required PPE after a pesticide application.
Question 5: Which of the following is NOT typically found on a pesticide product label?
- Precautionary statements
- Net contents
- The applicator's personal liability insurance information (Correct answer)
- First aid instructions
Correct answer: The applicator's personal liability insurance information
The applicator's personal liability insurance is not a label requirement; labels include product information, precautions, directions, and regulatory data.
Question 6: A label says 'Not for use on golf courses or sod farms.' This type of restriction is an example of which label element?
- Signal word
- Exempted use site
- Use site restriction (Correct answer)
- Environmental fate statement
Correct answer: Use site restriction
Use site restrictions explicitly exclude certain locations from legally permitted applications of that product.
Question 7: If a pesticide label says 'apply in a minimum of 20 gallons of water per acre,' what would be the consequence of applying in only 10 gallons per acre?
- The application would be more effective due to higher concentration
- It would violate the label and potentially cause phytotoxicity or poor pest control (Correct answer)
- It is acceptable as long as the a.i. rate per acre is correct
- It would have no effect on efficacy or compliance
Correct answer: It would violate the label and potentially cause phytotoxicity or poor pest control
Applying below the minimum carrier volume stated on the label is a label violation and can result in poor coverage, phytotoxicity, or crop damage.
