Y 4' 5 i The Division of Entomology and Economic Zoology f 4 6 l MONG the many important problems taking the time of the members of the A Division of Entomology and Economic Zoology is the one concerning the Q44 control of injurious insects. The insects for the most part do their damage x . . . . ' before they are recognized as dangerous and it is only by keeping constantly on guard that the grower can combat these insidious pests. One of the principal methods of N Q6 combating injurious insects is by the use of insecticides such as paris green, arsenate of lil. lead, nicotine, oil or soap. To kill a chewing insect an internal or stomach poison is required. The principal ingredient in the most of these stomach poisons is arsenic. When used in a spray the 3 is particles of poison are held in suspension in the liquid and settle down on the leaf when the Water evaporates. Much experimental work is required to determine the value of an aj insecticide. The sticky quality is one of the valuable assets of a stomach insecticide. ' 131 . . . lx MQ In the picture Professor A. L. Strand has just demonstrated the electrical charge present on the particles in a brand of arsenate of lead. It has been proven that where the spray has a charge different from the leaf to be sprayed, the poison will stick better. As the leaf usually has a negative charge it is necessary for best results to have a poison fl-. W' - . . , . Mxlq with a positive charge. At the present time several manufacturers of stomach poisons X-Y . . . Eg sul are trying to do this for their products. iflffv .. ,1 A lliimr, Y .M ,W Y , V, Y Y W .. ff? tf::EZf'147i?'Tf.f?3f ff-T f3ff5if- 1'-'XT' :'2fi--51555 YQ f A Page Tbiriy-seven

The experimental work in these fields covers a variety of cultural problems N, and is most extensively developed in the breeding of improved fruits and vegetables, li 3 including potatoes, especially adapted to Minnesota conditions. The instruction given Q on the campus is offered to four rather distinct groups,-students in the Graduate 4 . . . , xx' School of the University, undergraduate students in the College' of Agriculture, For- iafx estry and Home Economics, students in the School of Agriculture, and Short Course l' u n s 1 I u n Xl students. In addition to the week's program of horticultural instruction given during 1 Y Farmers' and Home-Makers' Week, a short course for commercial florists and another in by general horticulture are offered. In the extension field a wide correspondence is main- ' ll ' ' u A 4 u 1 tained and in the absence of a regular extension specialist in horticulture all members N A . . . - . . . g of the staff cooperate in attending meetings and demonstrations in various parts of the y state.

The Division of Farm Management and Agricultural Economics HE farmer encounters not only problems of technical production such as those involved in feeding, breeding, disease control, handling of soils, growing of crops, but also problems of an economic nature. In fact technical production problems usually have economic aspects. For this reason, students of agriculture need to study the economic side of their industry as well as the technical. The field of work of this Division is to supply this need and to assist farmers through studying economic problems of their industry. Courses in farm management and organization and farm records are given to students in the School of Agriculture. An extensive list of courses is offered to students in the College of Agriculture, Forestry and Home Economics and to graduate students, including principles of economics, rural economics, farm management, natural resources, marketing, agricultural cooperation, statistics, prices, accounting, land economics and farm finance. Specific problems are studied as a part of the research work of the division including projects obtaining data on efliciency and cost factors in farming, marketing methods and problems, market organizations, factors influencing prices, 0 questions of agricultural taxation, and credit problems. The work of the Division ,KJ is planned to give training to students in economic principles affecting agriculture and so to acquaint them with economic problems confronting the farmer.
