From the Preface:

This compendium was prepared for all those interested in rice and the diseases that affect it. It is hoped that the technical descriptions and illustrations will assist in identification, further study, and ultimately better management and control of the maladies that limit the availability of rice as a food stable for millions of the world’s population.

Because rice is grown and studied under diverse climates and cultural conditions and in many counties, the literature is broad, diverse, and in some cases scattered and difficult to obtain and translate. We have attempted to ensure that the most recent information is included but fully realize that some may have been overlooked. Since much of the existing knowledge on rice diseases is unavailable to many rice researchers in the world, a major purpose of the compendium is to stimulate further communication among rice pathologists, which should eventually lead to an improved product.

A broad array of diseases affects all parts of the rice plant and often places major restraints on rice production. Certain diseases are limited in occurrence because of the absence of environmental conditions favoring pathogen establishment and disease development, whereas others, the viruses and mycoplasmalike organisms, are limited by the absence of the vectors.
