  • Connecticut's Beech Trees Severely Impacted by Beech Leaf Disease [PDF, 345 KB]

    • Jun 6, 2022
    • Connecticut Agricultural Experiment Station.

    • Scientists from the Connecticut Agricultural Experiment Station (CAES) are reporting that Beech Leaf Disease (BLD) has increased dramatically in both severity and distribution in 2022 compared to 2021. First detected in lower Fairfield County in 2019, BLD is now widespread on American beech (Fagus grandifolia) throughout all eight Connecticut counties, with symptoms most severe in Fairfield, New Haven, Middlesex and New London Counties. Given that BLD is now widely established throughout Connecticut, reports of BLD to CAES and DEEP are no longer requested.

  • Emerald Ash Borer in Connecticut

    • Connecticut Department of Energy & Environmental Protection.

    • The Emerald ash borer was first found in Connecticut during the week of July 16, 2012. Since that first find in Prospect, EAB has been found in many other parts of the state, particularly in towns in central and western Connecticut. DEEP, the CT Agricultural Experiment Station, USDA APHIS PPQ and the U.S. Forest Service are working together with local partners to slow the spread of the insect and to take steps to minimize its impact. This will be a long-term effort on the part of all involved.

  • Invasive and Potentially Invasive Plant Early Detection List

    • University of Connecticut. Connecticut Invasive Plant Working Group.

    • These plants are known to be invasive or potentially invasive in Connecticut and are on Connecticut's list of Invasive and Potentially Invasive Plants. They are known to be present only in relatively low numbers at limited locations in Connecticut. These species should be considered for control and eradication efforts in the state when resources are available. If you find these species: Report your findings immediately to the CT Invasive Plant Coordinator at

State and Local Government
  • Connecticut Integrated Pest Management Program

    • University of Connecticut. College of Agriculture, Health, and Natural Resources.

    • Integrated Pest Management (IPM) is a sustainable and scientific approach to managing pests. IPM practitioners base decisions on information that is collected systematically as they integrate economic, environmental and social goals. This approach applies to any situation, agricultural or urban, and is flexible enough to accommodate the changing demands of agriculture, commerce and society.

      The University of Connecticut IPM Program staff members work directly with and provide educational outreach to commercial growers, natural area managers, groundskeepers, educators and the general public in Connecticut. In addition, they conduct research and offer extension programs in these areas: Fruit, Greenhouse, Invasive Species, IPM Curriculum, Nursery, Turf & Landscape and Vegetables.
