Trouble began in the late 1950s when the initial spread of water hyacinth became a nuisance for boaters. Water hyacinth and water moss have been choking many water bodies in the country, causing serious ecological and economic problems. The plant is ideal for composting. Several insects and fungi have been identified as control agents for water hyacinth. The mixture can be left in piles to compost, the warmer climate of tropical countries accelerating the process and producing a rich pathogen free compost which can be applied directly to the soil. Biological control. Dehydrated water hyacinth has been added to the diet of channel catfish fingerlings to increase their growth. The residue from the digestion process provides a fertiliser rich in nutrients. They have developed a locally manufactured production plant for producing fibreboard for general-purpose use and also a bituminised board for use as a low cost roofing material. Investigations into the use of bitumen coated boards for roofing are underway. The 3 main mechanisms used are biological, chemical and physical control. Water hyacinth has to be pre-treated before entering the digester (macerated, chopped or beaten) to promote digestion and to remove air entrapped in the tissue of the plant which would cause it to float. Biological control is the use of host specific natural enemies to reduce the population density of a pest. The boards are floated in a vat on water and then finished in a hand press and hung to dry. There is still no firm consensus on the design of an appropriate water hyacinth biogas digester. Success is hard to measure when the exact scale of the problem is not clearly defined and is anyway growing rapidly. ISSN 1857- 7431. To eradicate or control water hyacinth, physical, chemical, and biological methods are widely applied throughout the world. Water hyacinth root compost has nevertheless been used with good results as a propagation medium for house plants. It is however costly, using either land-based ‘clamshell’ bucket cranes, draglines or booms or, alternatively, water based machinery such as mowers, dredges, barges or specially designed aquatic weed harvesters.

Use water hyacinth! extremely di cult to control this determined water hyacinth species [8, 17]. CAB International: Organisation dealing with weed science and pest management In the Philippines water hyacinth is dried and used to make baskets and matting for domestic use. The plant originated in the Amazon Basin and was introduced into many parts of the world as an ornamental garden pond plant due to its beauty. Regardless of its problems, water hyacinth has been found to be useful for industrial, agricultural, household and environmental purposes. a practical handbook of uses for the water hyacinth from across the world. In the last 10 years the rapid spread of the plant in many parts of Africa has led to great concern. Such methods are suitable for only relatively small areas. Notwithstanding energetic gains in water hyacinth-bioenergy systems, there is a wide range of uncertainty in their economic viability due to underdeveloped extraction and processing technologies. Water hyacinth grows over a wide variety of wetland types from lakes, streams, ponds, waterways, ditches and backwater areas. Destroyer boat chopping water hyacinth in the St Johns River. With regards to its control, the mechanical method is the most cost-effective, followed by the biological, manual and chemical methods. California State Parks Division of Boating and Waterways manages an integrated pest control program that uses several methods to control hyacinth growth, including herbicides, mechanical harvesting, and insects implemented by the U.S. Department of Agriculture’s Agricultural Research Service. FAV control by water hyacinth weevils (Neochetina bruchi and Neochetina eichhorniae) have been used… The application of herbicides for controlling water hyacinth has been carried out for many years. Other fish such as the tilapia, silver carp and the silver dollar fish are all aquatic and can be used to control aquatic weeds. One such design has been tested in Bangladesh by a team from Warwick University, UK and the Housing and Building Research Institute, Dhaka, Bangladesh. Quantification of the problem is often extremely difficult. Water hyacinth is an aggressive invader and can form thick mats. In Florida, where for 100 years this weed had the upper-hand in water management, the water hyacinth in most places is under “maintenance control”: field crews constantly working to keep the plant numbers at their lowest possible levels, in exchange for the rivers and lakes remaining usable. Application can be from the ground or from the air and requires skilled operators. Water hyacinth is frequently branded as the world’s worst aquatic weed due to its invasive potential, negative impact on aquatic ecosystems, and the cost it necessitates to control it. Water quality can be affected by the invasion of water hyacinth. Chemical control is the least favoured due the unknown long-term effects on the environment and the communities with which it comes into contact. Water hyacinth can be found in many places of the world, which indicates that this aquatic weed is prone to adaptation and can tolerate considerable environmental variation (Julien, 2008). Biological Control. Dehydrated water hyacinth has been added to the diet of channel catfish fingerlings to increase their growth. It seems that the systematic use of successive vetiver hedges along the river and lake beds, beside the positive impact on the bank protection, shows positive results in retaining nutrients, pollutants and sediments from the run-off to flow in the water.

Water hyacinth can be used as a vegetable, fodder, green manure, compost and mulch for soil improvement. ... Herbicidal weed control of water hyacinth . Even quantifying the coverage of the weed is difficult on bodies of water which are as large and geographically complex as Lake Victoria. The stalk from the plant is shredded lengthways to expose the fibres and then left to dry for several days. The physical method is employed by directly harvesting, cutting, and removing the plant using machines or manual removing by hands and hand tools. Another fast-growing nonnative, hydrilla grows from the bottom, making it harder to manage. The manatee or sea cow has also been suggested as another herbivore which could be used for aquatic weed control. • http://www.sidney.ars.usda.gov/scientists/neal/water_h/consortium.htm A healthy acre of water hyacinths can weigh up to 200 tons! It also causes practical problems for marine transportation, fishing and at intakes for hydro power and irrigation schemes. Where water levels can be manipulated within a body of water, raising the water level can be used as a tool for managing the seed bank. To reduce the need for large volume digesters high rate digestion techniques have been employed. The first project is quite large with 120 producers involved in paper manufacture. In Florida, water hyacinth once clogged up and choked a major waterway. Water hyacinth (Eichhornia crassipes), South American spongeplant (Limnobium laevigatum) and Uruguay water primrose (Ludwigia hexapetala) are floating, aquatic invasive plants that are not native to California.They grow in wetlands, marshes, shallow water bodies, slow moving waterways, lakes, reservoirs, and rivers. 2. If the stalks still contain moisture then this can cause the product to rot quite quickly. Approximately 16,600 ha of water hyacinth control were treated annually from 2000 to 2013 (A. Perret, 2015, personal communication). Water hyacinths thrive on sewage; they absorb and digest waste water pollutants, converting sewage effluents to relatively clean water. Water hyacinth has also been used indirectly to feed fish. S.W., Tumwater, WA 98512, USA. (if ingested uncooked it will cause sever skin irritation) The plant is rich in carotene. Many of these techniques require the support of a fleet of water and land-based vehicles for transporting the large quantities of water hyacinth which is removed. One major drawback is that it can take a long time to initiate such projects because it can take several years for the insect population to reach a population density sufficient to tackle the pest problem. 8.The Water hyacinth Problem in Tropical Africa, Proceedings of the first meeting of the International Water Hyacinth Consortium, Hill, G., Waage, J. and Phiri, G., World Bank, 18-19 March 1997. Researchers are trying to find economic use so that these problem plants become a resource for income generation. Water hyacinth is a common fodder plant in the third world especially Africa though excessive use can be toxic. The design was for a small (8.3 cubic metre) baffled reactor which was fed with juiced water hyacinth. Since the water hyacinths are so prolific, harvesting them for industrial use serves also as a means of environmental control. See the Water hyacinth fact sheet (PDF, 386KB) for herbicide control and application rates. Figure 3: The scale of the problem is considerable © Paul Calvert/Practical Action. All have slender rootstocks, In north-east India, the Philippines, Thailand and Vietnam the water hyacinth's stems are used as a braiding material and a source of fibers.

In Benin, a startup is using water hyacinth to fight pollution. The result is a significant decrease in turbidity due to the removal of flocs and also slight reduction in organic matter in the water. It is also becoming a serious hazard to lake transport on Lake Victoria as large floating islands of water hyacinth form, while many of the inland waterways of south east Asia have been all but abandoned. - … Microbial decomposition breaks down the fats, lipids, proteins, sugars and starches. The compost increases soil fertility and crop yield and generally improves the quality of the soil. It will eat submerged or floating plants and also bank grasses. Water hyacinth and water moss have been choking many water bodies in the country, causing serious ecological and economic problems. In developing countries where mineral fertiliser is expensive, it is an elegant solution to the problem of water hyacinth proliferation and also poor soil quality. He states that with an energy density of 8.3 GJ/m3 this would be comparable with the energy density of charcoal at 9.6 GJ/m3. Researchers are trying to find economic use so that these problem plants become a resource for income generation. This aquatic perennial plant has stolons - that is, the plant can spread by broken plant parts, which can start new plants. Harnessing its considerable productivity is considered as a sustainable and possibly less expensive method of control. Proceedings of the International Water Hyacinth Consortium, World Bank, Washington, 18-19 March 1997 The mature plant consists of long, pendant roots, rhizomes, stolons, leaves, inflorescences and fruit clusters. 3.The Water Hyacinth, Herfjord, T., Osthagen, H.
