Long-term Control and Seedbank Depletion of Annual Ryegrass: Management Strategies

Long-term Control and Seedbank Depletion of Annual Ryegrass: Management Strategies

Annual ryegrass is a major winter annual weed of the southern Australian wheat-belt, which naturalised after its introduction as a pasture species.

If not managed effectively, ryegrass can significantly reduce the yield of winter crops. Many populations of ryegrass have developed resistance to selective grass herbicides used in crops, making post-emergent control difficult.

Growers must now plan carefully how to best manage ryegrass populations, and considerations start with crop choices and the associated weed control options available.

A succession of years with multiple and diverse control options used in varying cropping phases is central to successful ryegrass management.

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.
