Pesticide Applicator Training for Private Use vs. Commercial

There are 2 types of training, Commercial and Private. Most independent farmers fall in the private certification category rather than the commercial licensing. Commercial licensing is for businesses and custom applicators who spray for more acres and more individuals than a private (self) certification allows. To learn more visit:

  • Private Applicator: A person who applies restricted-use (pesticide label identifies) pesticide to produce an agricultural commodity AND pesticides are applied on property that they own or rent, or their employer owns or rents. If an applicator does not meet BOTH parts of the definition, they are considered commercial applicators. Examples of commercial applicators: Lawn care company or County Highway employee.
