    Tiger Pear Cladode Swap

    Do you have tiger pear (Cylindropuntia aurantiaca)?

    IMG 0131

    Tiger pear is extremely hardy, thriving in a range of habitats. This includes the slopes and nearby plains, where large localised infestations still thrive. Segments break from established plants easily and are transported by water, stock and car tyres.

    Tiger pear is a spreading or climbing cactus rarely more than 40 cm high.  The plant consists of numerous segments up to 20cm long. Each segment has large spines up to 5 cm long. Flowers are yellow. Fruits are egg-shaped with a depressed top. They are 2.5–3.5 cm long and are red to purple when ripe. Plants form seeds, however, the species is a sterile hybrid and only spreads vegetatively by segments or fruit which root where they contact the ground.

    How do I control it?

    If you have an infestation of tiger pear contact your local weed officer on how to best control it. If you live in the Narrabri Shire or the Gwydir Shires, you can partake in a cladode swap.

    What is a cladode?

    Opuntia spp. have succulent, jointed cladodes, which are also known as pads or stem segments. Cladodes are generally flat, cylindrical or occasionally fan shaped and green in colour.

    What is a cladode swap?

    A cladode swap is when you bring in clean (no soil or ants) fresh (recently collected), undamaged (cleanly broken off) cladodes (segments) and the weed officer will swap you for cladodes infected with Dactylopius austrinus, a cochineal species that specifically targets tiger pear. You can then release these infected cladodes in tiger pear plants that are up wind of your core infestation. As a result, the wind will then disperse the crawlers (juvenile cochineal) onto the surrounding plants. Make sure you securely place the cladodes in the plants by using a pair of long handled tongs.
