This essential reference contains 56 color photographs and accompanying text for identification, prevention, diagnosing, and controlling chrysanthemum diseases. Diseases are arranged according to casual agents for easy reference. Infectious diseases caused by fungi, bacteria, viruses, viroids, phytoplasmas, and nematodes are covered first followed by noninfectious diseases caused by physiological problems, environmental imbalances, air pollution, pesticide toxicity, and nutritional deficiencies and toxicities. A glossary, index, and selected references are also included.
