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 approximately 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 about 6–10 cm in length.

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 1.5 mL/1 L of water with a foliar spray.

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