Pesticide Label Reading

Core PrincipleProfessional Level

Understanding all sections of pesticide labels - target pests, application rates, timing, precautions, PPE, re-entry intervals, and legal requirements.

Detailed Overview

Labels are legal documents that must be followed exactly. Label sections: (1) Product name and EPA registration number: identifies specific product and approval. (2) Signal word: DANGER (highly toxic), WARNING (moderately toxic), CAUTION (slightly toxic). Indicates acute toxicity. (3) Active ingredient: chemical name and percent concentration. (4) Target pests: specifies which pests product labeled to control - using on unlisted pest is violation. (5) Application sites: where product can be legally applied - using on unlisted sites prohibited. (6) Directions for use: how to mix and apply. Mandatory - must follow exactly. (7) Application rates: minimum and maximum amounts allowed. Cannot exceed maximum. (8) Timing and frequency: when and how often can apply. (9) PPE requirements: what protective equipment applicator must wear. (10) Environmental hazards: warnings about fish toxicity, groundwater concerns, bee protection. (11) Re-entry interval (REI): how long people must stay out of treated area. (12) Storage and disposal: how to handle product safely. Reading labels: read entirely before first use, refer to label when questions arise, keep labels accessible, update when revised. Legal principle: label is law - any use not specifically permitted is prohibited.
