On the last day of April, we took to the air to get a view of the current state of the Lagarosiphon spread around Roys Bay and the Wanaka Marina complex.
The team from Aquatec completed the application of Diquat as a weed control measure in Roys Bay, on Feb 22nd.
Several site visits have been made since then and Boffamiscal is reporting a successful application and that there was a very good “take’ of the treatment.
Marina managers will be attending the annual Lake Wanaka Lagarosiphon Management Committee meeting on May 10th hosted by the LINZ Biosecurity and Biodiversity Team
The draft agenda is:
- An overview of 2022/23 control works
- A summary of NIWA scientific monitoring results
- A summary of NIWA scientific monitoring results
- An update on any additional works LINZ has underway at this site
- Round table discussion looking at priorities for the 2023/24 season
Check below for frequently asked questions published from NIWA relating to the Use of Diquat and the need for control of Lagarosiphon
