Seen this plant? Parthenium weed

Parthenium weed (Parthenium hysterophorus) invades pastures and crops. It can cause severe human health problems and may cause health problems in livestock.

Parthenium weed has recently been found near Walgett, Forbes and Engadine. It may also have spread into other locations in NSW.

Look for it along roadsides, especially those that have regular traffic from Queensland such as the Newell Highway.

Regularly check areas where grain and hay have been fed to livestock, especially after rain and if it has come from Queensland.
