The aquatic plant water hyacinth (Eichhornia crassipes) was first recorded in South Africa during the early part of the 20th century. The plant has since spread across the country and is found in water bodies in both sub-tropical and temperate areas. The biology, ecology and impacts of water hyacinth are well studied, but sound and cost-effective management of it remains an enormous challenge in South Africa. Since the 1970s, control programmes have focused on the use of herbicides, with some…

Effects of salinity and nutrients on water hyacinth and its biological control agent, Neochetina bruchi

Elucidating abiotic factors important for weed growth and weevil survival may increase effectiveness of water hyacinth management practices and potential effects of salinity via other exposures to weevils need to be investigated.

Aquatic Weeds and the Grand Ethiopian Renaissance Dam

Aquatic vegetation are constant problems on reservoirs, lakes, wetlands and waterways around the world with water hyacinth being the most problematic. In recent years water hyacinth has expanded in

A Comprehensive Evaluation of the Existing Approaches for Controlling and Managing the Proliferation of Water Hyacinth (Eichhornia crassipes): Review

The proliferation of the invasive Water hyacinth (WH) plant leads to ecological, economic, public health, and agricultural problems. Several efforts have been deployed to control its spread, but no

Living with floating vegetation invasions

This work analyzed floating plant coverage on 20 reservoirs across the world’s tropics and subtropics, using time-series of LANDSAT remote-sensing imagery to propose a more nuanced perspective on floating vegetation invasions.

Strategies for waterhyacinth (Eichhornia crassipes) control in Mexico

In Mexico, more than 40 000 ha of dams, lakes, canals and drains are infested with waterhyacinth (Eichhornia crassipes). To prevail over the problems resulting from this infestation, specific

Biological Control of Water Hyacinth Under Conditions of Maintenance Management: Can Herbicides and Insects Be Integrated?

Water hyacinth infestations under maintenance control were minimal when compared to unmanaged sites, and Reproductive status of the weevils improved with increased plant quality, which suggests that biological and herbicidal controls should be integrated.

Multiple regression analysis showed that the nitrogen mineralization potential of meadow marsh soil was the main factor affecting DOC production, while no significant correlation was observed between DOC release and leachate pH.
