Controlling Important Fungous and Insect Enemies of the Pear in the Humid Sections of the Pacific Northwest

Description: "Pear growers of the coast regions of Washington and Oregon can greatly increase the yields of their trees by careful spraying at the right time and with the proper materials. The losses occurring at present are largely due to pear scab and various insect pests. This bulletin describes the more important fungus and insect enemies of the pear in the region mentioned and gives directions for combating them. It also tells how to prepare the spray materials needed and how to apply them. A spraying schedule, showing concisely when and with what to spray, is included." -- p. 2

Dry Farming for Better Wheat Yields: The Columbia and Snake River Basins

Description: "This bulletin deals in particular with the dry farming methods practiced on grain farms in the Pacific Northwest where the rainfall is less than 18 to 20 inches annually, but it also contains advice helpful to all farmers of that region who practice summer-fallowing. Its purpose is to show the possibility of increasing crop yields in the dry-farming areas by using improved methods, and to discuss the practices which have been found most advantageous.... The purposes of summer-fallowing and details of the methods of their accomplishment are presented, with the application of these methods to the cultivation of "blow" soils and "nonblow" soils, and methods are suggested for preventing and stopping the blowing of soils. Attention is given to the seeding of winter and of spring wheat, and suggestions are made for properly maintaining the organic matter in the soil." -- p. 2

Strawberry Culture: Western United States

Description: "This bulletin applies to that part of the United States in which ordinary farm crops are grown largely under irrigation. It describes methods practiced in the more important commercial strawberry-growing districts in the irrigated regions of the West; it aims to aid those familiar only with local and perhaps unsatisfactory methods, as well as inexperienced prospective growers. The fundamental principles of the irrigation of strawberries are substantially the same as those which apply in the growing of other crops. Details of operation must necessarily be governed largely by the character of the crop grown. Since strawberries in the humid regions frequently suffer from drought, which causes heavy losses in the developing fruit, the information may prove suggestive to many growers in those localities who could install an irrigation system at small expense. Detailed information is also given as to soils and their preparation, different training systems, propagation, planting, culture, the leading varieties, harvesting, and shipping. Methods of using surplus strawberries for preserves and jams, for canning, and for flavoring for various purposes are given." -- p. 3
