Private Applicators

The Colorado Pesticide Applicators' Act requires that a person may not use restricted-use or state-restricted-use pesticides unless licensed (certified) by the Colorado Department of Agriculture (CDA).  The Colorado Private Pesticide Applicator License is required of individuals who use or supervise the use of restricted-use pesticides on land in agricultural production that is owned, leased, or rented by them or their employer.

CDA has a two-part system for private pesticide license renewal:

  1. Applicators accumulate the seven (7) required Continuing Education Credits (CECs)
  2. Applicators pay a renewal fee ($75.00) to the Colorado Department of Agriculture

Colorado Private Pesticide Applicator Licenses are issued for three years.  Continuing Education Credits (recetification credits) can be obtained at any time during the three year license cycle.

All Colorado Private Pesticide Applicator licenses expire on the applicator’s birthday.  Renewal application forms are mailed to the Private Applicator two (2) months before the expiration date.  If a licensee does not receive the renewal notice, a copy may be requested by calling the Pesticide Section at 303-869-9064.   It is important that licensees inform CDA of any address change.

To renew a license, the licensee must complete the renewal notice and send it back to the
CDA Pesticide Section with renewal fee ($75.00) and have accumulated the required seven (7) recertification credits.

If you do not acquire the required continuing education credits or let your license lapse you must retest in order to be licensed through the
Colorado Department of Agriculture.

Call CDA 303-869-9064 for further information.
