Four sections cover foliar diseases; root and stem diseases; virus and mycoplasma diseases; and miscellaneous problems that mimic diseases, followed by 11 tables listing plants susceptible to various diseases and viruses. The last section (a full three-quarters of the book) is a list of color photographs illustrating common diseases by plant, since the same disease can sometimes look different on different plants species. Includes a glossary. Annotation copyright Book News, Inc. Portland, Or.
