Subject: LGOIMA request - roadside spraying / weed control

I refer to your Official Information request of 5 October 2019 asking for details on Council's spend for roadside spraying and weed control, and reply as follows:

• How much does Council spend on roadside spraying per annum?

The annual budget for rural spraying is approximately $90-100k which allows for spraying of rural roadside verges, cycleways, street furniture, plant pests and weed control in kerb and channels.

• What are the different chemical herbicides?

The maintenance contractors for the above spraying typically use Glyphosate for spraying rural verges, street furniture, and kerb and channel. Tordon brushkiller and Meturon are typically used for pest plant (noxious weed) control.

• What is the annual calendar of weed control, for example, how often are culverts and road signs sprayed and how often playgrounds and parks.
