What is the term for the active ingredient in pesticides in its pure form?

The term for the active ingredient in pesticides in its pure form is referred to as "technical material." This designation indicates the unprocessed chemical component that is responsible for the pesticidal effects. Technical material is important because it serves as the base from which various pesticide formulations are created.

Formulation refers to the combination of active ingredients and other substances, like solvents or inert ingredients, that create the final product. Concentration generally pertains to the amount of active ingredient present in a specific volume or weight of the formulation but does not denote the pure chemical form. Active compound is a similar term but is often used interchangeably with active ingredient and does not specifically denote the pure, unformulated version. Understanding these distinctions helps clarify the roles and definitions of pesticide components within the context of pest management practices.
