A pesticide is any substance or mixture of substances intended for:
> repelling, or
> mitigating any pest.
Though often misunderstood to refer only to insecticides, the term pesticide also applies to herbicides, fungicides, and various other substances used to control pests.
Under United States law, a pesticide is also any substance or mixture of substances intended for use as a plant regulator, defoliant, or desiccant.

Pesticide Certification/Recertification and Pesticide Licensing
It is best to know the difference between Pesticide CERTIFICATION and Pesticide LICENSING.
CERTIFICATION is the process of demonstrating a person knows how to handle and apply pesticides in a safe and responsible manner. Certification examinations must be taken in specific categories of application to obtain a pesticide license. A passing score of 70% or higher on pesticide exams is required to become certified.Certification is the first step to obtaining a pesticide license.
Certification is valid for up to five (5) years and begins when the required tests are passed and ends on December 31st of the fifth calendar year. If you qualify for certification in the last 45 days of the year (November 17th through December 31st), the certification period is extended through the calendar year and the next five (5) years. For example:
Test Date Certification End Date
January 2, 2013 December 31, 2017
November 16, 2012 December 31, 2016
November 17, 2012 December 31, 2017
Just passing pesticide exams does not mean an individual is licensed!
LICENSING is the process to obtain the actual license that shows that a person has met certification requirements to make specific pesticide applications under that license. To get a license: (1) After passing the exams, fill out the correct form, (2) pay the license fee and any other associated fees; (3) submit both to ODA. All licenses are renewed annually, except for the Private Applicator license, which is renewed every 5 years.
