Due to recent rainfall combined with warm conditions we have seen an increase in the amount of caltrop around the town this summer season.
What is Caltrop?
Caltrop (Tribulus terrestris) is a pesky pest plant which produces spiky burrs throughout summer and autumn. Up to 1000 fruit can be produced on each plant, with a total of up to 20,000 seeds.
The seeds germinate after summer rain and plants grow rapidly, flowering and forming new burrs within three to five weeks.
Caltrop originates from the Saharan area of North Africa. It is thought to have been introduced to Australia, contaminating seed products.
Is caltrop illegal? Absolutely! It's officially declared a weed under the Landscape South Australia Act 2019. While councils are doing their part, our community are our greatest helpers! Let's be proactive, stay informed, and take action. Together, we can work towards bringing caltrop under control.
Why is caltrop a problem?
Caltrop spines are a hazard to stock, damaging the feet, mouth, stomach and intestines of animals. It is toxic to sheep and may present similar problems to native fauna.
Injury to people often occurs around farm buildings, roadsides, on property and recreational areas. Caltrop burrs are a scorn to cyclists as they puncture tyres easily.
Caltrop devalues produce which is contaminated by it, and is a fault in wool. Its spines cause injury to fruit pickers and shearers and it’s a significant pest in summer crops as it competes for soil moisture.
