This book was released on 1988 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alligatorweed (Alternanthera philoxeroides (Mart.) Griseb.) is an exotic South American plant introduced into the United States prior to 1897. It rapidly developed into problem levels throughout most southern states, where it outcompetes native vegetation and interferes with navigation and recreational use of waterways. Three biological control agents Agasicles hygrophila (Selman and Vogt), Amynothrips andersoni (O'Neill) and Vogita malloi (Pastrana) were released in the United States between 1964 and 1970 for the control of alligatorweed. A review of the releases and population development of these insect species was conducted through 1972 by US Department of Agriculture scientists. The objectives of this study were to: (a) determine the current extent of the alligatorweed population in each state and ascertain whether or not it occurred at problem levels, (b) define the current population levels of biocontrol agents at selected original release sites and assess their impacts on the alligatorweed population, (c) describe the current distribution of each species of biocontrol agent in each state, (d) identify environmental factors influencing the effectiveness of each biocontrol agent, and (e) provide recommendations for managers to enhance the effectiveness of each biocontrol agent in areas where control has not been achieved.

Download or read book Influence of Environmental Parameters on Penoxsulam Control of Alligatorweed alternanthera Philoxeroides in Rice oryza Sativa written by Samuel Duane Willingham and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Alligatorweed is a perennial plant which reproduces vegetatively and has spread from waterways into canals and ultimately into rice fields of Louisiana and Texas. Penoxsulam is a new acetolactate synthase (ALS) inhibiting broad-spectrum herbicide that was registered for rice in 2005. Previous research on alligatorweed control has focused mainly in aquatic areas and in the rice producing regions of Louisiana with little success. Research is limited using penoxsulam for alligatorweed control in rice production and results vary between year and location. Variability could be due to growth habit and resource allocation of this perennial species. Therefore, field and laboratory experiments were conducted from 2004 to 2007 to: 1) evaluate the effects of select rice herbicides on alligatorweed control, 2) determine the absorption and translocation efficiency and the effect of propanil on penoxsulam in alligatorweed 3) access the environmental effects of temperature on penoxsulam efficacy and determine application timing to avoid antagonism with propanil and, 4) evaluate the effects of flood timing and rice cultivars on rice root stunting and plant foliar injury from penoxsulam applications. Alligatorweed control was obtained from penoxsulam or bispyribac-sodium applied alone; however, mixtures with propanil were antagonistic. Day temperatures at 21 C increased efficacy of penoxsulam compared to 27 and 30 C day temperatures. Delaying propanil applications 3 days following penoxsulam applications were required at 21 and 27 C and 10 days at 30 C in order to avoid antagonism. Alligatorweed absorbed up to 33% of penoxsulam when applied alone, but most was retained in treated leaves (29%). Propanil reduced penoxsulam absorption into alligatorweed with only 22% of total penoxsulam recovered being absorbed by alligatorweed. More than 50% remained on the leaf surface of the treated leaf. Previous research has indicated root stunting of rice plants from ALS inhibiting herbicides. When various rice varieties were permanently flooded one week after herbicide application of penoxsulam, root stunting was greater compared to delaying flood establishment 7 or 14 days after treatment. Significant root stunting, however, did not affect rice yield.

Available in PDF, EPUB and Kindle. Book excerpt: Applications of 2 lb/A 2,4-dichlorophenoxy acetic acid (2,4-D) coordinated with alligatorweed flea beetle (Agasicles hygrophila) feeding damage resulted in the deterioration of subsurface mats of alligatorweed (Alternanthera philoxeroides (Mart.) Griseb.). The constant pressure on the surface alligatorweed growth, when using the integration method, appeared to deplete the subsurface carbohydrate reserves in alligatorweed stems. The integrated control in laboratory and small plot experiments has yielded a greater reduction of floating alligatorweed mats than is attainable with either agent alone. (Modified author abstract).

Book excerpt: "Alligator weed (Alternanthera philoxeroides) is a major weed of world importance and a “weed of national significance” to Australia where it is proclaimed noxious in all states. In spite of a concentrated effort with herbicides and insect biological control, the core infestation in NSW is still inadequately controlled and acts as a reservoir for new outbreaks throughout Australia. Inundative biological control with plant pathogens (mycoherbicide) is seen as a “softer” alternative to chemicals and could be integrated with existing control methods to give better levels of control."

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).
