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.

This book was released on 1961 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: DDT was sprayed at 0.5 pound per acre for elm spanworm control in two drainages in north Georgia in both 1959 and 1960. In one drainage, precautions were taken to avoid the stream, and no significant mortality to aquatic organisms resulted. In the other drainage, DDT reached the stream in a normal spray operation, and serious depletion of aquatic invertebrates resulted. Recovery of bottom organisms was rapid, and total numbers of invertebrates were up to pre-treatment levels after four months.
