Rules for aerial application of herbicides and biocides

Before you apply a pesticide by aerial application, you should also notify:
- local beekeeper groups, at least 48 hours before application
- the local council, 24 to 48 hours before application
- occupants or owners of property within 25 metres of the area to be treated, 24 to 48 hours before application
- the person in charge of any school, hospital or other institution within 150 metres of the flight path, 24 to 48 hours before application
