Active ingredients on a pesticide label will be?

• A. Described by hazard class only
• B. Shown as a single chemical name
• C. Listed by name and percentage
• D. Listed by date and batch number

Answer: (C)

Active ingredients are shown with their exact chemical names and the percentage they comprise of the product. This labeling tells you exactly what active compounds are present and how much of each one is in the formulation, which is essential for calculating application rates, understanding potency, and assessing potential hazards. If there are multiple actives, each one’s name and its percentage appear, so you know the contribution of every active component.

The other possibilities don’t fit because hazard class alone doesn’t identify the chemicals or their amounts, listing just a single chemical name wouldn’t reveal how concentrated it is (and a product can contain more than one active ingredient), and date and batch number pertain to manufacturing tracking rather than the composition of the product.
