Description
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.
