Growsafe Label Reading and Safety Data Sheets 1 — Questions and Answers
Question 1: What is the most important document to read before using any agrichemical?
- The product label (Correct answer)
- The safety data sheet (SDS)
- The manufacturer's website
- The regional council pest management plan
Correct answer: The product label
The product label is the primary legal document governing the use of an agrichemical. It contains the EPA-approved instructions and precautions. Using the product contrary to the label is unlawful.
Question 2: What information is found in the 'precautionary statements' section of an agrichemical label?
- Actions to take to prevent exposure or harm, including PPE requirements and application precautions (Correct answer)
- Only emergency contact phone numbers
- Only information about storage requirements
- Only the maximum application rate per hectare
Correct answer: Actions to take to prevent exposure or harm, including PPE requirements and application precautions
Precautionary statements describe the actions required to prevent harm — including PPE to wear, handling precautions, environmental care statements, and storage and disposal instructions.
Question 3: What does the 'active ingredient' section of an agrichemical label tell the user?
- The chemical compound responsible for the pest control action and its concentration in the product (Correct answer)
- The trade name under which the product is sold
- The name of the manufacturing company
- The crops the product is registered for use on
Correct answer: The chemical compound responsible for the pest control action and its concentration in the product
The active ingredient section identifies the chemical compound that provides the pest control effect and states its concentration. This is important for understanding the hazard and checking SDS information.
Question 4: What does the 'directions for use' section of an agrichemical label specify?
- The target pests, application rates, timing, crop registration, and method of application (Correct answer)
- Only the maximum application rate
- Only the dilution ratio for tank mixing
- Only the re-entry interval and pre-harvest interval
Correct answer: The target pests, application rates, timing, crop registration, and method of application
The directions for use section provides comprehensive application guidance including what crops the product is registered for, what pests it controls, application rates, timing, and method. This is the operational core of the label.
Question 5: What does the 'withholding period' (WHP) mean on a livestock product or a product used near grazing animals?
- The minimum time between application and when animals may safely re-enter the treated area or when their produce may be used (Correct answer)
- The maximum time a product can be stored after opening
- The time required between application and the next rainfall event
- The period after application during which the product is most effective
Correct answer: The minimum time between application and when animals may safely re-enter the treated area or when their produce may be used
The withholding period specifies the minimum time that must elapse before treated animals may be slaughtered for food or their milk/eggs collected, ensuring residues fall within safe limits.
Question 6: What does the signal word 'CAUTION' on an agrichemical label indicate?
- The product poses some hazard but is at the lower end of the risk scale — standard precautions are required (Correct answer)
- The product is highly toxic and the strictest PPE must be worn
- The product is only hazardous to the environment, not to humans
- The product is banned for residential use but approved for commercial use
Correct answer: The product poses some hazard but is at the lower end of the risk scale — standard precautions are required
Signal words form a hazard hierarchy. 'CAUTION' indicates a lower level of hazard than 'WARNING' or 'DANGER', but standard precautions and PPE as specified on the label are still required.
