' 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.

DIVISION OF HORTICULTURE an HE Dixision of Horticulture embraces four distinct types of work, vegetable if T? ture In each of these fields teaching, research and extension work occupy ' V137 I yn 1 growing, fruit growing, fruit breeding, landscape gardening and floricul- :ff . 57 ' a prominent position. A brief summary of some of the experimental work in connection with the above fields will best indicate the scope of the Division's activities. In the Vegetable Section one of the leading projects has to do with the breeding and improvement of potatoes. A few years ago the Vegetable Section introduced a small strain of Hubbard squash known as Kitchenette. Tl1e Fruit Growing Section has a project on testing of varieties of new fruits which involves the inspection of forty co-operative trial stations scattered about the state. Minnesota presents so many variations in soil and climate that it becomes necessary to make many trials to determine the adaptability of a new variety of fruit. This section is also undertaking to domesticate the northern blueberry. The Section of Fruit Breeding centers its activities largely at the State Fruit Breeding Farm where 110 acres of land are devoted entirely to the production of new hardy fruits. During the I8 years that this farm has been operated 32 new varieties have been introduced in addition to many others now under trial wl1icl1 will probably be given to the pnblic within a few years. The Section of Landscape Gardening and Floriculture is making a study of the adaptation of varieties of ornamental plants and flowers to various parts of Minnesota. In this connection the landscaping of homes and public grounds is being promoted wherever feasible throughout the state. 1 ., ,sr f ,-- '- V 'iff 1 i i ' 1 f ' I ' H.: - . n 'fn ' f ' 4-.1 Q' i -v A .1 ..i'1,1.l ' .
