18 November 1999

Further to advice in the September and October Newsletters, the Water Directorate is now pleased to inform all Water Managers that a new algaecide called CUPRICIDE has now been registered with NRA and available for use in drinking water storages, irrigation canals, fish farms, farm dams and many other uses.

CUPRICIDE is a complexed chilated copper and unlike copper sulphate, provides maximum algicidal efficiency with low marine toxicity.

The two registered products are CUPRICIDE and COPTROL and it is recommended that prices be checked before purchase.

Water Managers are advised that it is illegal to use an unregistered algaecide and the Water Directorate recommends use of only an algaecide registered with the NRA for use in potable water.

For manufacturers names, details etc or for further information, please contact the Coordinator of the Water Directorate's Blue Green Algae Sub-Committee, Mr Mervyn Chapman.
