Ongoing activities in the biological control of Water Hyacinth in Egypt. Solms . 100 of the world's worst invasive alien species: a selection the global invasive species database. One hectare of healthy E. crassipes can weigh as much as 415 metric tons (Schardt 1997). Management and control strategies ought to consider the mechanism an agent uses to control E. crassipes, whether the agent or combination of agents are appropriate for a given environment with an infestation of E.crassipes, and what growth parameters would be most appropriate for evaluating the efficacy of the agent. Madsen. Mart.) Biological and, Integrated Control of Water Hyacinth, Eichhornia crassipes: Proceedings of the Second Meeting of the Global Working Group for the Biological and Integrated Control of Water Hyacinth, 9-12 October 2000. Water conditions: Temperature: 68 - 86° F (20 - 30 ° C) pH: 6.0 - 8.0 dGH: 2-12. Fish preyed heavily on native amphipod Hyalella azteca that was more abundant in the native pennywort. 2001). Hill, M.J. Byrne, and A. Bownes. Randall, and M.C. Center for Environmental Research and Conservation. Genetic uniformity characterizes the invasive spread of water hyacinth (Eichhornia crassipes), a clonal aquatic plant. Rhode Island Department of Environmental Management. 1987. Eichhornia crassipes exhibits alternative physiological responses in response to varying nutrient concentrations. The Michigan Department of Natural Resources and the U.S. EPA have an early detection and rapid response plant regarding the establishment of E. crassipes (Ankney 2012). The information also gives insight into the impact of environmental ... estimated from the map. Interactions within pairs of biological control agents on water hyacinth, Eichhornia crassipes. Greenhouses within the Great Lakes basin commercially culture and sell E. crassipes for use in water gardens, thus, it may escape and spread into larger water bodies. Langeland, K.A., and K.C. Hydrobiologia 807: 377. https://doi.org/10.1007/s10750-017-3413-y. (floating water hyacinth) Plants Exotic. In high (7.6 mg N/L, 1.37 mg P/L), medium (2.5 mg N/L, 0.316 mg P/L), and low (.034 mg N/L, .024 mg P/L) nutrient treatments Cornops aquaticum (applied at a density of 1 insect per plant) reduced plant growth by 67%, 100%, and 400%, respectively (Bownes et al. Ecological Economics 45:105-117. https://www.researchgate.net/profile/Hugo_De_Groote/publication/223915650_Economic_impact_of_biological_control_of_water_hyacinth_in_Southern_Benin/links/55927cdf08aed6ec4bf893f4.pdf. In Caohai and Dianchi lakes in Yunnan province, southwestern China, E. crassipes competed with native plants for water, nutrients, and space, and contributed to the reduction in native plant diversity (Jianqing et al. Eichhornia crassipes has been reported to tolerate salinities of 0-8.8 ppt, with growth rate decreasing with increasing salinity (Rotella and Luken 2012). It is being provided to meet the need for timely best science. Getting the upper hand against water hyacinth can be a real challenge depending on the size of the infestation youâre trying to tackle. 2005). § 46). Eichhornia crassipes has the potential for high socio-economic impact if introduced to the Great Lakes. Invasive Species Specialist Group (ISSG), Auckland, New Zealand. Submergence of E. crassipes also has been shown to lead to higher rates of regrowth in spring. Title 18 U.S. Code 46 states that it is a violation of the law to knowingly transport E. crassipes in interstate commerce or selling or purchasing the plant (18 U.S.C. Canberra, Australia. American Journal of Botany 73(12):1741-1747. http://www.jstor.org/stable/2444240. 2,4 D or glyphosate can be effective. The application of aquatic herbicide requires a permit. Originally formatted NAS fact sheet (Oct 2003), GLERL 4840 S. State Rd., Ann Arbor, MI 48108-9719 (734) 741-2235 According to this map most of West Africa, with the . Biological control initiatives against water hyacinth in South Africa: constraining factors, success and new courses of action, pp.33-38. The sale of this species is prohibited in Chicago and Illinois State, but not in Indiana, Michigan, Minnesota, New York, Ohio, Ontario, Pennsylvania, Quebec, or Wisconsin (Great Lakes Panel on Aquatic Nuisance Species 2012). Therefore, drawdowns and submergence are not effective in long-term control of E. crassipes in subtropical climates (Liu et al. Hill, M.J.W. Plants grown in water containing 3% seawater exhibited significant leaf necrosis after 28 days (Penfound and Earle 1948). Center, and D. Jianqing, eds. Potential pathway(s) of introduction: Dispersal, hitchhiking/fouling, unintentional release, stocking/planting, and escape from commercial culture.

(Salviniaceae), Pistia stratiotes L. (Araceae), Myriophyllum aquaticum (Vell.) Eichhornia crassipes reproduces vegetatively through the production of ramets and an abundance of seeds. 2009). Great Lakes Panel on Aquatic Nuisance Species. 2007. Chemical: Registered aquatic herbicides can provide temporary control of water hyacinth in small scale applications. Eichhornia crassipes has a moderate probability of establishment if introduced to the Great Lakes (Confidence level: High). One acre of water-hyacinth can yearly deposit as much as 500 tons of rotting plant material on the bottom of a waterway. In addition, the infestation of E. crassipes resulted in increased transportation costs, blockage of irrigation canals, and difficulties in electricity and water extraction.
