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.

Click on any photos for a larger view.

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.

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.

Non-Chemical Options:
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.
Biological control 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, including Bingara, Inverell, Gravesend and Yetman. All release sites are being monitored by NSW DPI's Weed Biological Control Unit. Results to date have been very patchy. Results unreliable to date - not recommended for new and/or lightly/moderately infested areas.
Chemical Options: According to NSW DPI’s excellent booklet “Noxious and Environmental Weed Control Handbook (Fourth Edition)”, treatments for Echium species (Paterson's curse and Viper’s Bugloss) include:
