Description
Springer Epidemiology and Management of Root Diseases 1st Editon 2011 Softbound by C.Lee Campbell, D.Michael Benson
Root disease epidemics, because much of the activity takes place in soil and out of sight, pose special challenges to growers who seek to manage them and to scientists who study them. All relevant topics of root disease epidemics and their management are presented: The critical aspects of specific disease components including inoculum, host roots, mycorrhiza and the soil environment are explored. Challenges of disease assessment and the temporal and spatial aspects of epidemic development are considered, and approaches to root disease management including host resistance, chemical, biological and cultural management are discussed in detail. The book fulfills the needs of researchers, teachers, and practitioners of plant pathology. 1 Inoculum.- 1.1 Role of Inoculum in Root Disease Epidemics.- 1.2 Forms of Inoculum.- 1.3 Survival of Inoculum.- 1.4 Quantifying Inoculum in Soil.- 1.5 Inoculum Density-Disease Relationships.- 1.6 Concluding Remarks.- References.- 2 Host Roots.- 2.1 Introduction.- 2.2 Root Growth and Energy Availability.- 2.3 Root System Plasticity.- 2.4 Evaluation of Root Systems.- 2.5 Host Susceptibility.- 2.6 Measuring Susceptibility Alterations.- 2.7 The Future.- References.- 3 Mycorrhizae.- 3.1 Distribution and Ecological Impact of the Mycorrhizal Symbiosis.- 3.2 Productivity of Cultivated Mycorrhizal Plants.- 3.3 Mycorrhizae — Root Disease Relationships.- 3.4 Future Research.- References.- 4 The Soil Environment.- 4.1 Introduction.- 4.2 Components of the Physical Soil Environment.- 4.3 Influence of Edaphic Factors on Roots and Pathogens.- 4.4 Conclusions.- References.- 5 Estimating Disease Severity and Incidence.- 5.1 Role of Disease Assessment in Root Disease Epidemiology.- 5.2 Signs and Symptoms.- 5.3 Root and Shoot Symptoms.- 5.4 Disease Assessment.- 5.5 Sampling Considerations.- 5.6 Recommendations.- References.- 6 Temporal Aspects of the Development of Root Disease Epidemics.- 6.1 The Shapes of Disease Progress Curves.- 6.2 The Dynamics of Infection and Disease.- 6.3 Epidemiological Comparison of Treatments for the Control of Disease.- References.- 7 Spatial Aspects of the Development of Root Disease Epidemics.- 7.1 Importance of the Spatial Dimension for Analyzing Root Disease Epidemics.- 7.2 Aspects of Spatial Processes.- 7.3 Dispersal of Pathogen Propagules.- 7.4 Spatial Pattern of Propagules and Diseases.- 7.5 Applications of Spatial Analysis in Root Disease Epidemiology and Management.- References.- 8 Host Resistance.- 8.1 Introduction.- 8.2 Terminology.- 8.3 Components of Partial Resistance to Root Pathogens.- 8.4 Measurement of Resistance Components.- 8.5 Disease Avoidance and Disease Escape.- 8.6 Tolerance.- 8.7 Examples of Host-Pathogen Systems.- 8.8 Summary.- References.- 9 Chemical Management.- 9.1 Strategies for Use of Chemical Pesticides.- 9.2 Types of Chemical Pesticides.- 9.3 Chemical Management Approaches.- 9.4 Summary.- References.- 10 Biological Management.- 10.1 Ecological Opportunities for Biocontrol.- 10.2 Strategies for Biocontrol.- 10.3 Successful Implementation of Biocontrol.- References.- 11 Cultural Management.- 11.1 Approaches to Cultural Management.- 11.2 Strategies for Use of Cultural Management.- 11.3 Limitations.- 11.4 Novel Approaches.- 11.5 Conclusions.- References.
