Weed of the Moment:

Parthenium Weed - Parthenium hysterophorus

Parthenium weed

In Queensland, Parthenium is a Class 2 declared plant. Parthenium weed is an annual herb with a deep tap root and an erect stem that becomes woody with age. Its leaves are pale green, deeply lobed and covered with fine soft hairs. Small creamy white flowers occur on the tips of the stems with each flower containing 4 to 5 black seeds.

Parthenium weed is a vigorous species that colonises weak pastures with sparse ground gover. It will readily colonise disturbed, bare areas along roadsides and heavily stocked areas around yards and watering points. This weed can also colonise brigalow, gidgee and softwood scrub soils. Its presence reduces pasture production potential and the reliability of improved pasture establishment.

The plant is well established in Central Queensland and present in isolated infestations west to Longreach and in northern and southern Queensland.

If you have sighted this declared pest plant, please contact Council immediately.

More information and a fact sheet, which details control of Parthenium weed, can be found on the Department of Agriculture and Fisheries website.
