Helicopters are expected to be hovering over Lake Bistineau in the near future for a periodic, aerial herbicide spray to treat giant salvinia. The Louisiana Department of Wildlife and Fisheries has contracted two days of helicopter spraying to control plants in the large, open areas starting Tuesday, November 27.
Following the aerial treatment, airboats will concentrate on those areas with thick concentrations among dense cypress tree stands. The aerial spraying will be applied to selected areas where giant salvinia growth is particularly heavy.
