Pesticide Ingredients

Active Ingredient(s) + Other/Inert Ingredient(s) = Pesticide Product

Pesticide products include both active ingredients and other ingredients. Active ingredients are used to kill, control or repel the pest. Other ingredients may do a variety of jobs, like attracting the pest, spreading the active ingredients around, and/or reducing drift.

In order to know the risk associated with a pesticide, both toxicity and exposure must be considered. The toxicity depends on the ingredient(s), and this page is your gateway to a world of information about specific ingredients.

If you have questions about this, or any pesticide-related topic, please call NPIC at 1-800-858-7378 (8:00am - 12:00pm PST), or email us at npic@ace.orst.edu.
