Demonstrating integrated weed management strategies to control barley grass in low rainfall zone farming systems locations
Aims

This project is undertaking coordinated research with farming systems groups across the Southern and Western cropping regions to demonstrate tactics that can be reliably used to improve the management of barley grass.

Key messages
  • In 2019 the IMI system had the lowest barley grass plant numbers.
  • The Cultural Control strategy did not achieve the desired outcome of having a more even seed spread and increased competition in the inter row for barley grass weed control.
  • The medic pasture produced low dry matter compared to the cereal systems, had the highest barley grass population and the lowest competitive ability with the barley grass.
  • The loss of Group A herbicides to control barley grass within local pasture systems has the potential to change rotations and decrease farm profitability.
