The Lord Howe Island Board is planning to undertake targeted spot spray of Bitou Bush, Ground Asparagus and African Box Thorn on sea cliffs by helicopter. Surveillance for weeds in remote areas will also be undertaken!
Proposed dates: Between the 27th July to 30th August (potentially early September) pending weather and seabird activity). The program will be undertaken between 7:00 am and 4:00pm over a period of 5-7 days.
Method: Spot spraying will be undertaken using a forward mounted lance spray apparatus on a helicopter.
Pesticides: Metsulfuron 600 WG® Active Constituent: 600g/kg metsulfuron methyl &/or Clear Up Bio 360® Active Constituent: 360g/L isopropylamine salt (this will be the primary herbicide applied)
Pending track closures:
Some tracks will be temporarily closed during the operation. Timing of closures will be placed at track entrances & tracks monitored by LHIB staff.
Tracks will be reopened 1 hour after the operation concludes in the area.
