Paterson’s curse (Echium plantagineum) – also known as Salvation Jane – is widespread throughout many parts of New South Wales. It’s a handy resource for bees, but a curse to most grazing animals.
Paterson’s curse is easily distinguishable by its attractive, purple flowers. The plant produces thousands of seeds, often transported to new areas in hay and other forms of fodder. Wherever we see horses in a paddock, for example, we usually see Paterson’s curse that has arrived there via hay.
EFFECT ON ANIMALS
Paterson’s curse contains a number of alkaloids, at least one of which acts on the livers of animals causing loss of condition and eventual death in some cases.
Pigs and horses are most affected by continued exposure to Paterson’s curse. Their stomachs cannot fully process the plant material, resulting in chronic liver damage. Sheep, goats and cattle are affected but to a lesser extent.
Paterson’s curse also causes hay fever and skin irritation for some humans.
INFORMATION: Includes “Noxious Plants of Australia”, by Parsons and Cuthbertson [Inkata Press]. NSW DPI weeds website – detailed information on the plant and its management
Competitive pastures and/or good grazing management are important in helping to control this problem plant. Manual removal of new plants is an option for small infestations.
is showing some promise as a means of controlling serious, established infestations in some parts of NSW. The CSIRO and NSW DPI have been involved in a major biological program to control Paterson’s curse. Seven (7) different types of insects have been approved for release in Australia. The most promising insects so far include Mogulones larvatas and Mogulones geographicus. These insects have been released in many areas of NSW, at sites subsequently monitored by NSW DPI staff and local council weeds officers.
Results in northern NSW have been patchy, compared to the southern (and cooler) areas of the state where the program has had some noticeable successes – in fact, some news reports have quoted bee farmers as going crook because there has not been enough Paterson’s curse available for their bees!
More information on the biocontrol program can be found on the NSW DPI weeds website,
