Title: New control options for Cambomba Weed

New control options for Cambomba Weed

The herbicide ‘Shark’ (carfentrazone‐ethyl) has recently been registered for use on the water weed Cabomba.

Cabomba is a submerged aquatic weed that can invade freshwater lakes, dams and slow moving waterways.
Management of Cabomba, which is found along the eastern seaboard, had been limited to mechanical removal or using techniques such as shading. ‘Shark’ can only be applied to 50% of the water body at one time and there must be a 3 month gap between repeat treatments.
It can’t be used in flowing water or water to be used for human consumption and there is a 3 month withholding period for treated water being used for irrigation.
It is moderately toxic to fish and the restriction on applying to 50% of a water body at a time reduces the risk of fish death from low oxygen levels caused by the decomposition of rotting Cabomba.

 For more information and advice, contact Charles Mifsud, NSW DPI, on 02 6640 1662.

Has "Shark" also been approved for Qld waters?

Can think of anywhere that has cabomba that they could use it. All the lakes I know with it are used for water supply.
