The Nature and Practice of Biological Control of Plant Pathogens

This book explains how biocontrol works in soil, in crop residue, on the surface of the plant and in the plant. One of the principal concepts is that slight changes in an environmental factor produce striking effects in interactions among micro-organisms, or between them and the crop, and provide effective means of achieving biological control of plant pathogens. Pathogen suppresive soils are discussed in the context of the soil ecosystem and in relation to the source fields
