What are the methods to eradicate water hyacinth?

To eradicate or control water hyacinth, physical, chemical, and biological methods are widely applied throughout the world. The physical method is employed by directly harvesting, cutting, and removing the plant using machines or manual removing by hands and hand tools.

Is water hyacinth a problem?

What is the effect of water hyacinth on water?

In slow-moving water bodies, water hyacinth mats physically slow the flow of water, causing suspended particles to be precipitated, leading to silting. The reduced water flow can also cause flooding and adversely affect irrigation schemes.

How is water hyacinth controlled?

How to Control Water Hyacinth

1. Physical Management Options. Water Hyacinth can be removed by raking or seining it from the pond’s surface.
2. Biological Management Options. Since water hyacinth is the main food source for the Neochetina beetle, they are commonly used as a biological management factor for the plant.

What causes water hyacinth?

One of the fastest-growing plants known, water hyacinth reproduces primarily by way of runners or stolons, which eventually form daughter plants. Each plant additionally can produce thousands of seeds each year, and these seeds can remain viable for more than 28 years.

At the end of the spring season, the foliage will die back naturally. Remove when the leaves have turned brown to help prevent fungal diseases.

Why is the Water Hyacinth so successful?

Water hyacinth stems are spongy and filled with air spaces, which allow them to stay afloat easily. Water hyacinth leaves are fanlike and slightly cupped. This shape makes a very effective sail and allows the plants to spread easily over water bodies when the wind blows.

What is the importance of water hyacinth?

Water hyacinth is used for making textiles, paper and for camouflaging fish traps (Ecoport, 2011; Pieterse, 1997). It ferments rapidly due to its high water content and can supply biomass for biogas production.

How does water hyacinth affect the environment?

Water hyacinth can alter water clarity and decrease phytoplankton production, dissolved oxygen, nitrogen, phosphorous, heavy metals and concentrations of other contaminants. The effects of water hyacinth on ecological communities appear to be largely nonlinear.

What can Water Hyacinth be used for?

Dried stems are used for baskets and furniture. Water hyacinth fibers are used as raw material for paper. Since the plant has abundant nitrogen content, it can be used as a substrate for biogas production and the sludge obtained from the biogas.

Is water hyacinth good?
