Pesticide Management Program

Important Notice Regarding Reclassification of Neonicotinoid Pesticides
Public Act 16-17 requires that, not later than January 1, 2018, the Commissioner classify all neonicotinoids (as defined by the Act) that are labeled for treating plants, as restricted use.  Pursuant to the Act, the classification of pesticide products currently registered in Connecticut which contain clothianidin, dinotefuran, imidacloprid and thiamethoxam will be changed from general use to restricted use effective January 1, 2017. 

The Notice of Reclassification of Neonicotinoid Pesticides Used for Treating Plants and the Notice to Wholesalers/Distributors/Retailers provide a list of the affected pesticides and the schedule for implementing the Act. 

The main goal of the Pesticide Management Program is to prevent adverse human health or environmental effects from the misuse of pesticides.

Pesticide management programs include:

Application forms and instructions for aerial and aquatic pesticide applications
Nuisance Aquatic Vegetation Management Guidebook
Memorandum of Agreement between the Department of Public Health and the Department of Energy and Environmental Protection concerning the use of pesticides within public water supply watersheds and near public water supply wells.
Annual Aquatic Pesticide Use Summaries
Summaries of Methoprene/Resmethrin Use to Control Mosquitoes in the Coastal Area

Impact of EPA Registered Pesticides

The Department of Energy and Environmental Protection (DEEP) contracted Dr. Chensheng (Alex) Lu, Associate Professor of Environmental Exposure Biology at Harvard University to produce a  literature review and policy implication synthesis of the impact of EPA registered pesticides that are most widely used on turf and school grounds on the health of children and pollinators, including synergetic effects, using top-tier, peer-reviewed scientific journals.  Below are links to rough drafts of the literature review papers that are scheduled to be finalized by Dr. Lu this Fall.  DEEP will work with our state agency partners at the Department of Public Health, Department of Agriculture and Connecticut Agricultural Experiment Station to interpret Dr. Luís findings which will help lay the groundwork for public policy on pesticides.

Draft Report: A review of pesticide effects on sensitive receptors: children 
Final Report: A Meta-analysis of Sub-lethal Pesticide Exposure and Effects on Sensitive Receptors: Children 

Draft Report:  A review of pesticide effects on sensitive receptors: pollinators
Final Report:  A Review of Sub-lethal Systemic Neonicotinoid Insecticides Exposure and Effects on Sensitive Receptors: Pollinators

DEEP also held four municipal pesticide listening sessions, which were opportunities for municipalities to discuss challenges and opportunity with the current pesticide policy.  DEEP compiled the municipal thoughts into a summary presentation and shared this with all of the towns in a final meeting.
