Integrated weed management: pre-sowing tactics are not sufficient for controlling herbicide resistant annual ryegrass in the high rainfall zone locations
Aims

To assess the effectiveness and applicability of cultural control practices prior to crop seeding in combination with pre-emergent herbicides for the management of herbicide resistant annual ryegrass in the high rainfall zone of Victoria.

Key messages
  • Continuous cropping and a reliance on pre-sowing weed control measures is not an effective way to manage herbicide resistant annual ryegrass over the long term.
  • The increase in weed numbers over time can be limited by adopting an intensive and high cost herbicide strategy, but this will not deplete the seed bank.
  • Increasing annual ryegrass density was associated with decreased grain yield.
