The active ingredients on a pesticide label will be:

The active ingredients on a pesticide label will be:

• A. Listed by Name
• B. Listed by Chemical Compound
• C. Listed But Not Named
• D. Listed Only as a Percentage

Answer: (A)

The key idea is that regulatory labels identify the active substances by their names so you know exactly which chemical is providing the pesticidal action. Using the common name (the name you’d recognize and search for in safety data and usage guidance) lets applicators and regulators clearly identify the active ingredient and its hazards, rather than bogging things down with chemical formulas or isomer details. The label will also show how much of each active ingredient is present, but the identity must be stated by name. Listing only a percentage would leave you without knowing what chemical is doing the work, and listing a chemical compound or calling it “not named” would create ambiguity.
