Abstract

The class Oomycetes includes saprobes and pathogens of both plants and insects. However, the plant pathogens have been studied most intensively so will be the primary subject of this chapter. Important plant pathogens include Pythium, Phytophthora, and the Peronosporaceae, commonly known as the downy mildews. The mostly soil-borne Pythium and Phytophthora cause severe yield loss in many crops throughout the world. The Irish potato famine caused by Phytophthora infestans led to large-scale starvation and migration from Ireland in the middle of the 19th century. The downy mildews cause problems in many important food crops. Downy mildew of grape, caused by Plasmopara viticola, devastated European vineyards during the 1870s and 1880s until observations by Millardet led to the introduction of the first fungicide, Bordeaux mixture, to control fungal pathogens.
