Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Aquatic Pests on Irrigation Systems: Identification Guide Extensive infestations of obnoxious plants and certain aquatic animals cause problems on irrigation systems, such as reduction in carrying capacity of the system, increased evaporation and seepage, clogging of structures, adverse environmental impacts, and water loss through transpiration. Because of the many problems created by these growths, steps are usually necessary to control them or prevent their occurrence. The methods employed to control these plants and animals differ widely due to differences in the organisms, such as growth habitat, organism metabolism, size, growth stage, and genetic characteristics. Correct identification of the organism is therefore important to the proper control recommendation. The simplified identification guide was prepared in response to requests from irrigation project operators and other personnel involved with biological problems requiring identification aids. It consists essentially of an illustration and a narrative description of some of the commonly observed organisms that become pests on the operation of irrigation systems in the Western United States. Not all animal pests that inhabit irrigation systems are included because many of these common ones such as muskrat, certain fish, and crayfish are readily recognizable by irrigation operating personnel. Some of the more serious and marginal ditchbank weeds have been included to illustrate a few typical problems on canals and drains.

Book excerpt: Excerpt from A New Selective Spray for the Control of Certain Weeds The primary object of weed control is to increase yields at a profit to the grower.

Book excerpt: Excerpt from Suggested Guide for Chemical Control of Weeds Research in the field of weed control with chemicals is conducted by the United States Department of Agriculture, State agricultural experiment stations, and industrial organizations. Representatives of these groups meet periodically in four regional conferences to discuss research developments in the field of chemical weed control and to formulate suggestions on control practices. Some of the suggested weed-control practices of the conferences are summarized in this report in order to make them generally available to agricultural workers in the various States who advise with farm people.

This book was released on 2018-01-08 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Use of Aromatic Solvents for Control of Submersed Aquatic Weeds in Irrigation Channels Thorough dispersion of the chemicals in the water before coming into contact with weed growth was of utmost importance. Aromatic solvents are lighter than water. Unless completely dispersed, the emulsions did not extend to the bottom of the channel but tended to break up more rapidly, allowing the solvent to rise to the surface and evaporate. With conventional spray units, the introduction of chemicals im mediately above a weir or other structure, with a considerable drop and turbulent pool, usually promoted adequate dispersion (fig. In the absence of such structures, compressed - air booms, attached to large compressor units. And placed in the water immediately below the spray boom, provided agitation and chemical dispersion. The advantage of mixing the aromatic solvents with water prior to intro duction under high pressure has already been discussed in the section titled Equipment for Application.
