🚨 Biosecurity Alert: Invasive Tropical Soda Apple Detected in Silverdale and Scenic Rim Region 🚨
Biosecurity authorities, along with Scenic Rim Regional Council, have confirmed the positive detection of the highly invasive w**d Tropical Soda Apple (Solanum viarum) within the Silverdale area in the Scenic Rim Regional Council jurisdictions. This is the first detection positively identified in the Scenic Rim Region.
The positive identification was finalized following targeted field surveillance by Biosecurity Queensland and Scenic Rim Regional Council Biosecurity Officers. Local landholders, primary producers, and residents are being urged to immediately inspect their properties and report any suspected sightings to prevent the aggressive pest from establishing a foothold in the region and surrounding areas.
Tropical Soda Apple is a Category 3 restricted matter under the Biosecurity Act 2014. It poses a severe threat to Queensland's agricultural industries, native ecosystems, and livestock. 🌱⚠️ The prickly perennial shrub can grow up to 2 metres high and forms dense, impenetrable thickets that displace native vegetation and restrict livestock access to water and pasture. A single plant can produce up to 50,000 seeds per year, which are rapidly spread by cattle, feral pigs, birds, and water.
📍 Where to look:
• Cattle yards and spelling grounds 🐄
• Dams, creeks, storm run-off locations, and sediment catchment areas 💧
• Areas where cattle congregate (shaded locations) 🌳
🔎 What to look for:
• A dense, upright shrub growing 1 to 2 metres tall.
• Stems and leaves heavily armed with straight, cream-coloured prickles up to 2 cm long. 🌵
• Broad-shaped leaves varying in size, with larger leaves equivalent to a dinner plate on more mature plants. 🍽️
• Clusters of white flowers with yellow stamens. 🌼
• Round fruit varying in size from marble to golf ball shape, with pale to dark green veining (resembling a small watermelon 🍉) and turning bright yellow when fully ripe. 🟡
Landholders are reminded of their General Biosecurity Obligation (GBO) to take all reasonable steps to minimise the risks associated with invasive plants under their control. Livestock movements from infested areas should be restricted, and any machinery or vehicles passing through suspected zones must be thoroughly washed down. 🚜
❌ Do not attempt to move or dispose of the plant without guidance, as improper handling can inadvertently spread the seeds.
