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.

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.

In this issue, we learn about invasive species, their impacts, and what we can do to help stop their spread.

Classical biological control, which reunites invasive insects or plants that have spread in new, invaded areas with their natural enemies, is the only means of reducing permanently and over large areas the harm such invaders cause. Short of eradication, which is rarely practical once an invader has spread widely, this method is the only solution that does not depend on endless control activities and their associated costs. The purpose of this book is to highlight the value that programs of classical insect and weed control have provided to the United States over roughly the last 40 years (1985–2022).

This synthesis reviews federal, state, and regional approaches; prevention, early detection, and rapid responses; identification of aspects of operations and risks; statewide inventories; and information management. In particular, this report synthesizes the state of the practice in developing Integrated (Roadside) Vegetation Management, along with physical, chemical, biological, and cultural control mechanisms.

Ailanthus altissima (tree-of-heaven) is a rapidly growing invasive tree species introduced to the United States nearly 200 years ago. Today, this species is a common invader in many forests across the nation. Scientists with the Northern Research Station have identified a unique biological control measure for managing Ailanthus—Verticillium nonalfalfae, a native soil-borne fungus. Check out this latest issue of Rooted in Research that explores how Verticillium can reduce Ailanthus populations.
