Metro spokesman Themba Gadebe says their Environmental Resources Management Department has deployed the wetlands attendants team to regularly spray the hyacinth with herbicide to stop it from spreading.

“The herbicide spraying has been interrupted by the recent rains, but the team makes use of all the favourable weather conditions as and when they present themselves,” he says.
In the next few weeks the team will remove the hyacinth from the dam once it has dried up.
“The work at the Dersley dam will continue until the hyacinth cover is kept at an acceptable level,” says Gadebe.
