Department of Environment and Primary Industries (DEPI) staff are working to stem the spread of the ubiquitous weed at Illabrook, 40 kilometres south-west of Ballarat.

DEPI biosecurity officer Jesse Miller said Paterson’s Curse was of particular concern to the Illabrook area and if not controlled had the potential to reduce livestock carrying capacity and invade adjoining properties.

“Paterson’s curse is generally considered a widespread established weed throughout many parts of Victoria, but at Illabrook its growth is confined to a handful of properties, isolated from larger infestations in southwestern and central Victoria,” Mr Miller said.

“Over four years a DEPI compliance program has made significant progress in reducing the weed’s density. Annual property inspections have focussed on preventing seeding in spring and reducing the historic seed bank.”

Called Salvation Jane in South Australia, Paterson’s curse has some value in times of low rainfall as sheep fodder, and considerable value as a source of pollen for beekeeping. However, it out-competes more useful pasture species and is poisonous to grazing livestock, especially pigs and horses.

It germinates rapidly after autumn rains, competing for water, light and nutrients with desirable pasture species.

“DEPI staff will conduct property inspections during July and, where required, issue directions notices to control Paterson’s Curse,” Mr Miller said.

“Re-inspections to determine the level of Paterson’s curse control achieved will be undertaken during September before the plants seed.

“Landowners have a legal responsibility to manage declared noxious weeds and pest animals on their property to ensure they don’t adversely affect agricultural production on neighbouring farms or impact on the natural environment.”

Mr Miller said penalties could apply in cases where there was non-compliance for pest control.

“Under the Catchment and Land Protection Act 1994 landowners are liable for fines up to $34,000,” he said.
