Book excerpt: The use of herbicides coordinated with insect-feeding damage as a method for alligator weed management is discussed. Detailed studies on the integrated control method include the details of the research program relating to an integrated approach, the effects of water quality on the distribution of alligator weed and water hyacinth, the effects of water hardness on herbicide toxicity, and the evaluation of promising herbicides for the control of alligator weed and water lettuce. Color illustrations reproduced in black and white.

Book excerpt: The greatest success with the Agasicles as a biocontrol for alligator weed has been at experimental sites in Florida. The increased effectiveness of the alligator weed beetle in this area is believed to be related to the ability of the insect to overwinter. The Agasicles population usually has two peaks of activity in Florida as compared with one in other states. Alligator weed mats present at the beginning of the study reported herein have decreased in size and thickness. Plant competition has played an important role in controlling the alligator weed at the Goose Creek site by Agasicles and at several other sites in the southeastern states. The feeding of the Agasicles on alligator weed decreases its ability to compete with other aquatic plants. Other insects may be used to extend control over a greater geographic area. (Author).
Download or read book Weed Control Methods for River Basin Management written by E.O. Gangstad and published by CRC Press. This book was released on 2018-05-04 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic plants continue to create problems associated with navigation, flood control, agriculture, irrigation and drainage, values of lands, conservation of wildlife and fisheries, and water resource supply. While much research is being done to find more effective and economic control measures, there is now a great need to apply known facts to achieve a measure of control by the means available. It is the purpose of this volume to provide a scientifically documented treatise of the known facts as they apply to the control of aquatic weeds in river basins and their allied waterways with particular emphasis on alligator weed and water hyacinth.

Download or read book Weed Control Methods for Public Health Applications written by E.O. Gangstad and published by CRC Press. This book was released on 2018-05-04 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume includes measures of control of aquatic vegetation that harms human health, since water-related diseases exist in this environment. Although malaria has receded internationally due to the combined chemotherapeutic-insecticidal programs, recently it has resisted both medicines and insecticide control. Active malaria cases in the U.S. were fewer than a dozen before the Vietnam War, but in 1973 the figure was ab out 700, almost all traceable to returning military personnel. The disease could again become prevalent. Other diseases exist whose transmission is indirectly affected by aquatic weed conditions including filariasis, and various trematodiases, especially from the schistosomes, Chinese liver fluke, cattle liver fluke, Guinea worm, giant intestinal fluke, Asiatic lung fluke, and broad tapeworm. Waterweeds also support disease-pest arthropods, i.e., snipe flies, tabanids (horse, gad, deer, and greenheads), Clear Lake gnats, Mayflies, black flies, sandflies, and sewage flies.Ecosystem studies of impounded water research and development of herbivorous fish, and utilization of herbivorous fish in China, are also included in this volume.

Book excerpt: Preliminary experiments in 1968 indicated that water hyacinths and possibly other aquatic plants could be controlled by 10.6 micron laser radiation. Two effects were noted: an immediate plasmolysis directly proportional to laser energy and a secondary effect at lower levels of irradiation that resulted in death of the plant after a period of time. Studies made in 1969 indicated that split applications of laser energy were not more effective than continuous treatment. Plant count evaluations were significant at a minimum level of 0.5 joules per sqcm(J/sgcm). Histological examination of irradiated leaf tissue did not show extensive cell damage due to laser treatment. Studies made in 1970 indicated that twice-irradiated plants were affected at a level of about 70J/sqcm. (Author).
