GEORGE NEWS - Kariba weed management on the surface of the Garden Route Dam is going well and remains ongoing. The chemical and biological treatment since February was very successful, according to George Municipality Superintendent of Parks and Recreation, Priscilla Burgoyne. The weed at the Kat River continues to die off. This takes time, so the visual presence of dying weed gives the incorrect impression that it is not under control, she said. We are satisfied with the control of this section for now.

GEORGE NEWS - George Municipality is seeing excellent results following the release of 1 500 weevils, a small herbivorous beetle, as part of a multi-faceted plan to sustainably manage Kariba weed infestation in the Garden Route Dam. The municipality is fully aware of the presence of Kariba weed in the dam, as well as the causes for it, and is working alongside experts in the field to manage the problem holistically, said the municipal superintendent for Parks and Recreation, Priscilla Burgoyne.
Weevils of the species Cyrtobagous salviniae were released mid-February at the Kat River inlet into the dam and near the dam wall where most of the weed grows. Upon follow-up investigation, studies confirmed a 91% infection uptake, while a significant reduction in the amount of dead plant material is expected once the weevils have established.
