Types of pesticide applicators
Anyone can take the Private Applicator examination. A private applicator license is only intended to be used to apply or supervise the use of a restricted use pesticide for the purpose of producing an agricultural commodity.
- Under CRS 35-10-103(11.5), a Private Applicator is defined as: "any person who uses or supervises the use of a pesticide for purposes of producing any agricultural commodity on property owned or leased by the applicator or the applicator's employer or, if the pesticide is applied without compensation other than trading of personal services between producers of agricultural commodities, on the property of another person."
If a person wants to make pesticide applications for hire or apply restricted use pesticides for purposes other than producing an agricultural commodity, they must license as a commercial applicator and/or hold the appropriate Qualified Supervisor license.
