LINZ Pest Plant Control Programme 2010/11

Property owners, recreational, and other users of riverbeds and lakes are advised that herbicide spraying by aerial and / or ground methods is to be carried out to control pest plants on Crown Land. The pests to be controlled this season may include one, or a combination of the following pest plants: gorse, broom, briar rose, old man’s beard, banana passionfruit vine, lupin, nodding thistle, ragwort and wild ginger.

Herbicides containing the active ingredients Glyphosate, Picloram and Triclopyr may be used. Additives to aid absorption of the herbicides and prevent drift may also be used during treatment.

The work will commence no earlier than 1 October 2010 and will continue intermittently, as weather permits, up to 30 June 2011. Control works will not take place on public holidays, or at weekends which immediately precede or follow a public holiday, or during the period from 20 December 2010 to 10 January 2011.
