Publ. 78, 218 p.In young windbreaks, diseases caused by root-infecting fungi, leaf-spotting fungi, and abiotic factors such as adverse sites are very important. As windbreaks mature, heart rots, diebacks, and stem-canker diseases become significant. In general, on poor sites diseases normally associated with young trees may appear in older trees. On good sites, diseases of older trees may appear in younger trees. Diseases commonly encountered in young and old windbreaks in the Great Plains are listed. In this paper, tree diseases will be considered with reference to parts of trees affected: stems and branches, roots, and foliage.
