Pesticide Active Ingredients
Aug 23, 2018

Active ingredients are the chemicals in pesticide products that kill, control, or repel pests. For example, the active ingredients in a herbicide are the ingredient(s) that kill weeds. Often, the active ingredients make up a small portion of the whole product. Pesticide product labels include the name of each active ingredient and its concentration in the product.

  • The same active ingredient may be found in hundreds of pesticide products with different names.

  • Products with similar brand names may have different active ingredients.

  • Products with the same name and active ingredient(s) may have different concentrations.

  • Some active ingredients work on a broad spectrum of pests. Others are more targeted, killing only certain things.

  • There are families of active ingredients that work in the same basic way. Using active ingredients from different chemical families can slow the development of pesticide resistance.
