Pesticide Private Applicator Certification

In Connecticut, a farmer must be certified as a private applicator in order to purchase and use restricted use pesticides on agricultural crops.  (No certification is needed if a farmer does not use restricted use pesticides.) Only one certificate per farm is needed.

General Information

The pesticide private applicator certification program is open to persons who intend to use or supervise the use of restricted use pesticides on property owned or rented by them or their employer for the purpose of producing an agricultural commodity.  Federal regulations (40 CFR 171) prevent the State of Connecticut from certifying homeowners or home gardeners as private applicators.

Requirements for Certification

An examination is required before a private applicator certificate can be issued.

As a minimum requirement for certification, a private applicator must show that they possess a practical knowledge of laws pertaining to pesticide applications and the pest problems associated with their farming operation.  This practical knowledge includes ability to recognize common pests and damage caused by them.  Recognition is critical because it is the first step in control.  The private applicator must be able to recognize the pest problem before they select among the available pesticides.

Study Materials

The examination is based on the following publications:

  1. The Pesticide Applicator Training Manual (Core Manual) which can be purchased from

  2. Pesticide Private Applicator Study Manuals (Commodity Booklets)

    The commodity booklets are prepared as a study guide for those individuals seeking certification as private applicators in Connecticut.  Each one contains brief descriptions of the major pests of each crop, their life cycles and the damage they cause to the host plants. The commodity booklets are not to be considered a complete source of information.  Information on integrated pest management (IPM) and suggested spray schedules may be obtained from the Connecticut Cooperative Extension Service or Connecticut Agricultural Experiment Station at (203) 974-8500.

Additional Information

Certification Requirements

Any person who uses restricted use pesticides must be certified in order to be able to purchase such products.  With the exception of commercial applications, certification is not required if only general use pesticides are used.

Any person who sprays another's property in exchange for money must possess a commercial applicator's license.  However, individuals that are certified as a private applicator can spray another's property in exchange for services  (i.e. applicator might trade a spray job in the spring for help with harvest in the fall).

A farmer wishing to use restricted use pesticides must obtain a "private applicator's certificate."  The private applicator may then buy and apply restricted use pesticides on their own farm, property they rent or on the farms of others, provided that they do not get paid to do so.

It is not necessary for the certified private applicator to actually perform all pesticide applications.  An employee or family member can apply pesticides, however, the certificate holder is responsible for training the person who actually does the work, and must be available if needed.

Private applicators are required to maintain records with respect to each use of restricted use pesticide and must file a report of their usage with the DEEP on or before January 31st each year for the previous year's applications.

In accordance with state regulation 22a-66-5(e), if your address changes, you must notify the Pesticide Management Program within 30 days.
