Lagarosiphon Control

After some delays due to weather, the team from Aquatec completed the application of Diquat as a weed control measure in Roys bay, today Feb 22nd.

NIWA information states that Diquat has no risk for human health at the concentrations used for submerged weed control under prescribed use. As a precaution, it is recommended lake and river users in New Zealand don’t swim or fish in areas of lakes or rivers treated with diquat for 24 hours. As there is no fishing or swimming permitted on the Marina, this should not affect Marina use in any way.
