Statice: Biology, Ecology and IWM Tactics

Statice (Limonium lobatum) is a winter annual dicotyledonous weed of Mediterranean origin that has naturalised inland and along some coastal areas of southern Australia.

This herbaceous weed from the Plumbaginaceae family is often found in areas of low to moderate rainfall on sandy to loamy soils that are calcareous, sodic and of neutral to high pH.

Long-range dispersal is by seed, either through contamination of grain crops, harvest or tillage machinery, or by movement with livestock. Infestations are more common in pastures, roadsides and undisturbed habitats, however recently this weed has invaded cropping areas, particularly where crops are rotated with pasture.

In the absence of effective early control, deep-rooted statice plants can compete with crops for nutrients and moisture, reducing crop growth and yield potential. In dense stands, crop yield losses can be as high as 20 to 30%. Statice can also cause problems at harvest, with green leaf material often discolouring and contaminating grain.

Wild radish management and strategies to address herbicide resistance

Wild radish (Raphanus raphanistrum) is one of the most widespread and competitive broadleaf weeds of Australian cereal-growing regions. Increasing resistance to multiple herbicide modes of action is forcing growers to adopt diverse and integrated weed-control strategies to deal with this weed.

Northern IWM factsheet – common sowthistle

Common sowthistle (Sonchus oleraceus L.), also known as milk thistle, is a dicotyledonous annual weed. The plants are erect and fleshy and possess hollow, smooth stems that exude a milky latex when damaged. The weed can grow up to 1.5 m in height. Plants of common sowthistle can be either present as a rosette or upright in their growth form. Its leaves may vary in colour and the amount of serration on their margins (Figure 1). Common sowthistle seeds possess a pappus, which helps in seed dispersal through the wind.
