Pesticide Product Registration Requirements
All pesticides that are sold or used in Connecticut must be registered with the Department of Energy and Environmental Protection (DEEP) Pesticide Program. Pesticides are broadly defined and include insecticides, herbicides, antimicrobials, fungicides and most other products that are designed or marketed to control or repel a pest. The manufacturer or distributor is responsible for registering the product. In most cases, federal EPA registration must be obtained before the state registration process can begin. Note:
Pesticides exempt from federal registration under section 25(b) of FIFRA must be registered in Connecticut, more information here.
Alternate Brand Names (ABN) must be registered separately.
Section 22a-50(l) of the Connecticut General Statutes requires that the Commissioner classify neonicotinoids (as defined by section 22-61k of the Connecticut General Statutes) that are labeled for treating plants, as restricted use.
Applications must be submitted through DEEP's online product registration system.
