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.
Examination results are valid for one year from the date of the passed exam. In addition to testing, a license application must be completed to license initially or add a rider category (aerial or soil/non-soil fumigation).
The fee to license or to renew a Private Applicator license is $75.00. This is separate from any examination fees. There is no fee to add a license category. An individual private applicator license may be renewed through either examination or continuing education credits (CECs).
