' AQ LANT diseases cause tremendous losses to farmers every year. Rusts of cereals in 1916 caused a damage of two l1undrcd millions of dollars in the it T N? cereal crops of America. Practically every agricultural crop is subject to one or more diseases and some are susceptible to many. The diseases of potatoes constitute one of the most important factors, if not the most important, in potato production and even in the marketing of this crop. Seed treatment, soil treatment, spraying, and especially the development of resistant and immune varieties constitute some of the methods already known for Hghting plant diseases. Eradication of com- mon barberry is a means of assisting in the control of the destructive black stem rust of cereals. The Division of Plant Pathology and Botany is also engaged in working on many physiological problems of plants, such as resistance of plants to low tempera- tures, and in the analysis and study of purity and germination of seeds.
