Best Management Practices to Protect Groundwater

The New York State Department of Environmental Conservation, with input from CCE Suffolk and other stakeholders, developed the Long Island Pesticide Pollution Prevention Strategy as a blueprint for DEC, in consultation with stakeholders, to evaluate pesticide usage on Long Island, identify pesticides that have the greatest potential to cause adverse impacts, and work with partners to reduce or eliminate such usage or find alternatives that do not present such impacts. This approach will both protect Long Island’s water resources and encourage effective methods of pest management. More information about the Strategy can be found at

As one component of the Strategy, factsheets below were prepared for specific active ingredients to summarize best management practices, alternative active ingredients and non-pesticidal techniques for key or important targets of these pesticides in agriculture and commercial landscape management.

Detailed factsheets for proper use of atrazine, imidacloprid and mefenoxam in various commodities.

Mefenoxam for Nursery Uses

Mefenoxam for Greenhouse Uses

Mefenoxam for Potato and Tomato Uses

Atrazine for Sweet Corn Uses

Imidacloprid for Fruiting Vegetables

Imidacloprid for Tree and Shrub Use

Imidacloprid for Cucurbit (Vine) Crops

Imidacloprid for Commercial Turfgrass Use

Imidacloprid for Commercial Greenhouse Use

Imidacloprid for Potatoes

Protecting LI's Groundwater from Pesticide Contamination

The purpose of these factsheets are to provide information that can help Long Island growers select best management practices (BMPs) that will minimize groundwater contamination. BMPs are economically and environmentally sound measures that, when followed, aid the protection of water resources while ensuring the continued availability of pesticides.
