Dutch Elm Disease and the American Elm

This educational DVD is the perfect supplement to classes teaching the history and biology of Dutch elm disease, a major epidemic in the United States from the 1930s through the 1960s that is still killing thousands of American elms today. Through this case study students will:  -- learn to appreciate the aesthetic value of plants and the devastation of an epidemic.  -- understand monoculture and the effects this planting system has on spreading plant diseases.  -- be introduced to the role of an insect vector in the life cycle of a plant pathogenic fungus.  -- examine the roles people play in the spread and management of plant diseases.
