Weevils alone will not permanently eradicate Hartbeespoort Dam’s hyacinth problem
By Gofaone Motsamai
While the release of weevils into the hyacinth-infested waters of the Hartbeespoort Dam is a welcome development, these insects alone cannot be expected to permanently solve the dam’s pollution problem.
“The use of weevils must be part of an integrated plan to resolve the issue,” says Prof Wynand Malherbe from the North-West University’s (NWU’s) Water Research Group in the Unit for Environmental Sciences and Management.
