Extension Wild Blueberry Specialist and Assistant Professor of Horticulture
Professional Interests: Integrated Pest Management, Sustainable Agriculture
Research: Lily Calderwood’s research and education program aims to develop whole system approaches to wild blueberry production in Maine. Integrated Pest Management (IPM) is at the forefront of her work, which can improve the economic and ecological resilience of farms by incorporating subjects such as fertility, soil health, and plant physiology into pest management. Current research includes a weed survey of wild blueberry fields, tine weeding and cover cropping studies for organic weed management, mulching studies, crop and pest forecasting tools, and foliar fertilizer assessments. Past projects studied insect-plant interactions and biological control on lavender, cut flower, hop, dry bean, grains, and oilseeds. Her applied research and education helps growers to identify and address on-farm needs.
