Which name most accurately identifies the active ingredient of a pesticide?

The most accurate option that identifies the active ingredient of a pesticide is the chemical name. This name provides a precise description of the chemical structure of the active ingredient, following the rules of chemical nomenclature set by organizations such as the International Union of Pure and Applied Chemistry (IUPAC). The chemical name is scientifically recognized and gives insight into the molecular composition and potential chemical behavior of the pesticide.

While the trade name is the marketing name given to the pesticide formulation and can vary between manufacturers, it does not convey specific information about the active ingredient itself. The common name, although easier for consumers to recognize and use, is still not as definitive as the chemical name and may be based on various factors that do not fully describe the chemical structure. Therefore, the chemical name is the most accurate representation of the active ingredient in pesticides.
