Pesticide chemicals in their “raw” or unformulated state are not usually suitable for pest control. These concentrated active ingredients may not mix well with water, may be chemically unstable, and may be difficult to handle and transport. For these reasons, manufacturers add inert substances, such as clays and solvents, to improve application effectiveness, safety, handling, and storage. Inert ingredients do not usually possess pesticidal activity and are added to facilitate some purpose in the product. These ingredients are usually listed as “other ingredients” on the label. The mixture of active and inert ingredients is called a pesticide formulation. This formulation may consist of:

  • The pesticide active ingredient that controls the target pest
  • The carrier, such as an organic solvent or mineral clay
  • Adjuvants, such as emulsifiers, dispersants, stickers and spreaders
  • Other ingredients, such as stabilizers, safeners, dyes, and chemicals that improve or enhance pesticidal activity

Often the formulated product needs to be diluted with water or oil prior to application. Most baits, granules, gels, and dusts—however—are ready for use without additional dilution. Manufacturers package many specialized pesticides, such as products for households, in ready-to-use formulations.

A single active ingredient is often sold in several types of formulations. Abbreviations are frequently used to describe the formulation. Common abbreviations and their interpretations are listed in below. The amount of active ingredient (a.i.) and the kind of formulation are listed on the product label. For example, an 80% SP contains 80 percent by weight of active ingredient and is a “soluble powder.” If it is in a 10-pound bag, it contains 8 pounds of a.i. and 2 pounds of inert ingredient. Liquid formulations indicate the amount of a.i. in pounds per gallon. For example, 1E means 1 pound, and 4E means 4 pounds of the a.i. per gallon in an emulsifiable concentrate formulation.
