ABSTRACT
This chapter presents IPM strategies for disease control in landscapes in three parts. It describes the actions that can be taken to prevent or minimize disease occurrence in new plantings. The chapter discusses strategies for managing plants so as to minimize diseases in established plantings. Any action taken to improve host vigor should optimize defense responses to both bark and xylem pathogens. Landscape plants often have to be pruned in order to reduce their size, improve their shape, or ensure their safety. Despite tremendous interest by the mass media and the research community on the potential use of microorganisms to control plant diseases and a deluge of publications on the subject, only two have actually found their way into “mainstream” agriculture. Both are used to control diseases of trees and shrubs. The chapter presents innovations to strengthen IPM programs for the future.
