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…

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.
