Have you seen this weed?

Its long prickles, underground rhizomes and ability of spread seeds far and wide via birds and foxes make it a tough one to get under control.

Local Land Services regional weed coordinator Marita Sydes said Sticky Nightshade's been in the Central Tablelands since the 1980s, but it's been in isolated pockets. It's thought the weed first emerged during the drought in the 1980s and came in via stock feed.

"Now it's popping up in areas it's not been reported before, so we want to get the message out to landholders as to what it is and how to identify it," she said.

She said control can be challenging as the plant can sprout from any deep rhizomes left behind if it is dug out of the ground.

"It's not like thistles for example where they can be ploughed out when they are young to control them," Ms Sydes said.

"The best control we have is via chemicals."

She said may councils had been working to control single plant outbreaks when they were reported.

The weed is a native to warm temperate South America, but according to the LLS it now occurs as a weed in many countries.

In Australia, LLS said it is naturalised in Queensland, NSW, Western Australia and Victoria. In NSW it's mostly a weed of disturbed sites in and around Sydney and the Hunter, but has been collected in the Central West and Central Tablelands.

Recorded habitat types include roadsides, wastelands, agricultural land and dry sclerophyll forest.

Later this month a workshop in collaboration with Central Tablelands Regional Weed Committee, Cabonnne Council and Cowra Shire Council will be held for landholders to learn about Sticky Nightshade.

Landholders will not only learn about identifying the weed, but also have the opportunity to talk to local weeds officers about the best control options and the sort of impacts the weed may have on their property.

The workshop is planned for Wednesday, October 30 from 9.30am to 11am with the location still to be advised. However, for further information contact Marita Sydes 0439 334 282.

Sticky Nightshade (Solanum sisymbriifolium) is an emerging threat to landholders in the Central Tablelands.

Local Land Services regional weed coordinator, Marita Sydes said it is an invasive weed that competes with crop and pasture plants.

"Stock will avoid grazing areas of high density infestations," she said.

Sticky Nightshade is also able to invade more inaccessible sites such as rocky hillsides making control difficult.

Sticky Nightshade is a short lived perennial, but it produces a fruit which looks a bit like a small tomato and is spread by birds and foxes. The plant can also regenerate by growth from underground rhizomes.

Ms Sydes said it appears to also be spread by machinery and fodder brought into the area for drought feeding.

The core infestation was in the Panuara district in the upper reaches of the Belubula River, but it appears to be spreading with recent records of new incursions recorded in the Cabonne, Cowra, Blayney, Orange and Bathurst local government areas.

The Central Tablelands Regional Weeds Committee has been working with landholders and the NSW Department of Primary Industries to review the weed risk rating of Sticky Nightshade in the Central Tablelands region and have determined that Sticky Nightshade should now be considered for listing as a priority regional weed species in the Central Tablelands Regional Strategic Weed Management Plan.

Prior to listing, the Central Tablelands Regional Weeds Committee is seeking public feedback into the proposed recommendation.
