Dowson, W. J.
"A work of great importance at a time when world food stocks may be considerably reduced by bacterial plant diseases. Although the standard works are outdated by recent advances, this subject has not received such attention as have fungus diseases, virus diseases and insect pests. Yet bacterial diseases are causing severe losses to many crops in different parts of the world: to sugar cane and cotton, and among our own crops to stone fruits, potatoes and tomatoes, and to trees and ornamental plants."--Cover
