Statice seedbank persistance locations
Aims

To determine how long statice persists in the seedbank and to investigate the effect of crop and fallow rotations on statice control.

Key messages

• Statice seedbanks reduced with targeted management options in three years, providing no new seeds are allowed to set.
• Crop competition and crop-topping to prevent seed set can help to control statice.
• Statice can be hard to control, so good farm biosecurity is important to prevent the introduction of statice. This includes controlling statice in non-crops areas, such as laneways and fence-lines.
