Which of the following is NOT a component of the principle label?

The principle label of a pesticide product is a critical component that provides essential information regarding the product's safe and effective use. The elements that are included typically consist of details like the product's name, net contents, and class designation. The product's name identifies the pesticide, while net contents pertain to the amount of product contained within the packaging. Class designation indicates the type of pesticide based on its use, such as herbicide, insecticide, etc.

First-aid instructions, while important for ensuring safety in cases of exposure, are not typically considered a standard component of the principle label itself. They may be provided on an accompanying brochure or a safety data sheet but do not form a core part of the label, which focuses more on identification, usage, and regulatory compliance. Understanding this delineation helps clarify why first-aid instructions do not belong to the primary elements outlined on the principle label.
