Thornapple Description

Thornapple Identification

Thornapple usually grows to around 1.5 m in height and produces a globular fruit about 4 cm diameter with a circular crown on top and around 100 spines of variable length.

The leaves and stems are hairless or sparsely hairy, ending in white to lavender

coloured, trumpet shaped flowers that grow to around 6–10 cm.

Thornapple Control

Controlling Thornapple

Cultivation combined with a chemical treatment can be used for limited infestations as well as hand pushing tilling tools to remove the plant.
For more extensive thornapple infestations, it is recommended to use Tordon 75-D at 1.5mL/1L of water with a foliar spray.

Large, well established infestations require using Starane Advanced at 450mL/hectare to achieve best results.
