This revised edition maintains the clear, nontechnical format of the first, and covers the infectious diseases of shade trees, the major pathogens that cause them, and noninfectious diseases and their agents. Special topics include nonpathogenic conditions, disease diagnosis, and tree injection and implantation. Comprehensive disease control protocols, a detailed discussion of disease diagnosis, and tree diseases of the western and southern United States are among the useful additions to this widely used text and reference. This is an essential book for arboriculturists and students of aboriculture. Key Features * Only text available that deals exclusively with the diseases of shade trees * Emphasizes abiotic problems of shade trees, which account for most of the losses in the urban environment
