From the nineteenth century Irish potato famine to current widespread threats to forests and ecosystems in North and South America, Europe and Australia, the genus lives up to its reputation as the plant destroyer. This book provides an overview of "Phytophthora" species impacting crops, forests, nurseries, greenhouses and natural areas worldwide. Chapters cover major hosts, identification, epidemiology, management, current research, future perspectives and the impacts of globalization on "Phytophthora." "Phytophthora: A Global Perspective" is an essential resource for researchers and extension workers in plant pathology and crop protection.
