KVH works collaboratively with Regional Councils and landowners to manage wild kiwifruit populations and abandoned orchards to reduce biosecurity risk to the NZ kiwifruit industry.
Wild kiwifruit can germinate wherever birds deposit kiwifruit seeds or wherever discarded fruit has been thrown or dumped. Birds love to feed on kiwifruit that's left out on vines, in reject bins or on paddocks for stock feed. They then spread the seed that grows into wild kiwifruit vines in areas of native bush, forestry blocks and near orchards or farms.
Wild kiwifruit is a real biosecurity risk to New Zealand’s kiwifruit industry as wild vines can harbor Psa and other kiwifruit pests and diseases. It can also smother areas of New Zealand’s native bush and forest.
It’s important wild kiwifruit is reported so local regional councils or KVH can take appropriate action.
Growers—Remove unpicked fruit from vines and mulch as soon as possible. This prevents mass feeding by birds and allows the fruit to compost as quickly as possible.
Postharvest operators—Cover bins of reject fruit to prevent birds feeding on ripening fruit.
Farmers—Cover stockpiles of fruit with shade cloth, windbreak netting or something similar, to prevent birds from getting to any fruit. Feed out only what will be eaten by stock at one time to prevent birds from eating leftovers.
Members of the public—Be very careful with the disposal of kiwifruit, particularly while out in the bush.
How to kill wild kiwifruit plants
Cut vines at ground level. Apply Vigilant Gel® herbicide to the top and sides of the cut stump or any exposed roots. Ring-bark stumps or large roots with a machete or pruning saw to assist absorption of the herbicide gel. Carefully trace all vine stems to find where they may have taken root. Cut any rooted stems at ground level and apply Vigilant Gel®.
If you know the location of any unrecorded wild kiwifruit infestations, contact your local regional council or unitary authority with details so the infestation can be assessed and programmed for control.
