Plant Pathology: Volume I

Given three volumes in which to set out the principles of plant pathology, we found that the subject dissected easily into the required three segments: The Diseased Plant; The Pathogen; The Diseased Population. This distinction has not been emphasized hitherto. In fact, Stakman and Harrar (1957) in their excellent text say that "Diseases of individual plants are relatively unimportant, and plant pathology is therefore essentially a community aspect, or plant public health science."
