Moth plant is one of the most problematic weeds of North Island kiwifruit orchards and the pods are beginning to develop - they are currently flowering in most locations.

Growers should start the first round of control work now to avoid the need to pull masses of vines and pods out of shelter belts.

Seedlings will be establishing beneath shelter belts, ready to climb into trees before flowering and forming their distinctive seed pods. A skillfully used sharp hoe will kill emergent seedlings and is an effective organic control method. Alternatively, glyphosate applied at label rates is effective on emergent seedlings. Apply under low pressure ensuring no spray drift.

Moth plant is poisonous – the milky white sap can cause dermatitis so wear gloves and protective clothing when handling it.

There is a great video here from the Bay of Plenty Regional Council on control.
