Beech Leaf Disease
Beech leaf disease (BLD) affects and kills both native and ornamental beech tree species. It is associated with a nematode, Litylenchus crenatae mccannii. This disease has only been discovered in recent years and much about it, including the full cause and how it spreads, is still unknown.

Dr. James A. LaMondia
Plant Pathologist & Nematologist / Plant Breeder @The Connecticut Agricultural Experiment Station
Expertise in the biology and control of plant diseases caused by fungi, nematodes and complex diseases involving multiple soilborne pathogens. Areas of emphasis include non-chemical controls such plant resistance and the development of cropping systems with non-host or nematode-antagonistic plants. Examples include biofumigation with Brassicas, breeding for resistance to fungal, virus and nematode pathogens, and IPM programs for nematodes based on sampling and damage functions.
Dr. Robert E. Marra
Associate Scientist/Forest Pathologist @The Connecticut Agricultural Experiment Station
Dr. Marra’s research encompasses various aspects of tree and plant diseases of urban and natural ecosystems. His current research includes the population genetics, ecology, and dispersal dynamics of two important plant pathogenic fungi: Neonectria ditissima, the ascomycete that causes perennial target cankers on birch and other trees; and Fusarium palustre, the ascomycete associated with the decline of Spartina alterniflora in salt marshes of the eastern United States. Dr. Marra recently developed a methodology using sonic and electrical-resistance tomography to nondestructively measure the amount of carbon sequestered in trees, in order to investigate the role that internal decay in forest trees plays in carbon cycling and the mitigation of global warming through carbon sequestration. In addition to conducting surveys for diseases such as oak wilt and beech leaf disease, Dr. Marra is also developing molecular tools for tracking movement and spread of the beech leaf disease nematode.
