Pesticide Labels, Labeling, and Safety Data Sheets
Pesticide Labels, Labeling, and Safety Data Sheets
This domain tests the legal difference between a label, labeling, and an SDS, and your ability to find the information that controls a safe application.
Core rules
- The label is the EPA-approved document on or attached to the container; labeling includes the label plus other EPA-required materials such as brochures, worker protection information, and supplemental labeling.
- The label is the law: follow directions for use; off-label use is illegal.
- Key parts: EPA registration number, ingredient statement, signal word, first aid, PPE, environmental hazards, directions for use, site/pest list, rates, reentry interval (REI), storage/disposal.
- An SDS is a hazard communication document with 16 sections. It is not the label and does not authorize use.
- Restricted-use pesticides (RUPs) require a certified applicator.
- Check supplemental labeling for special local needs (SLN) or emergency exemptions.
Worked example
Two products list the same active ingredient. Product A is labeled for turf only; Product B is labeled for turf and ornamental beds. The customer wants bed treatment. Reasoning: same active ingredient does not mean same legal site. Choose B if the pest and rate match; using A in beds would be off-label even though the chemistry is identical. Check the REI before scheduling reentry.
Traps
- Treating the SDS as the label.
- Assuming a product labeled "for lawns" can be used on all turf sites.
- Missing a supplemental label that changes the rate or site.
- Ignoring "must" versus "may" statements.
- Applying a RUP without certification.
