Excerpt from Diseases of Fruit Crops It is a curious but logical fact that in spite of a rapidly increasing population and an increased demand for fruit, there has been a decided decrease in the number of deciduous fruit trees in the United States during the last thirty years. With this marked decrease in the number of trees, there has been only a slight decrease in total production, and it is probable that there has been an increase in fruit which actually reaches the ultimate consumer. It is evident that diseases and insects have eliminated millions of fruit trees and that those which remain have been made much more productive owing to the control of pests. This more efficient and more stable production in spite of the increase in the number Of parasites has been made possible mainly by the scientific development of plant protection. Efficient plant protection has been made possible only by a thorough knowledge of the nature and cause of the diseases of plants.
