Controlling wild oats locations

To evaluate the effect of long term management strategies on the wild oat seedbank and measure the efficacy of various control techniques.

Key messages
  • Two years of full wild oat control did not exhaust the seedbank to a manageable level.
  • A selective post emergent herbicide or an early hay cut were the most effective strategies for reducing the wild oat seedbank.
