“Sea spurge, Euphorbia paralias, is a major plant invader of our southern beaches and it continues to spread. Our scientists have found a fungus, Venturia paralias, that is highly specific to sea spurge. This fungus was recently approved for release as a biocontrol agent of the plant in Australia. We hope it will help manage this weed that invades beaches from Perth in Western Australia to the mid-north coast of New South Wales, and around Tasmania’s coastline.”
“This fungus (Venturia paralias) is native to Europe. It was first collected in France”
“Want to participate in a community release of the biocontrol agent? Here’s how you can get involved. If you are in Victoria or Tasmania and identify an infestation, you need to obtain approval from the land manager or owner of the site to make a release. Once you have approval, contact us. We will send you a kit. The kits will contain the fungus and an explanation of how to inoculate the sea spurge plants with the biocontrol agent. Lastly, we encourage you to inspire others to take part.”
