Key Points
- Prevention is better than cure - if possible, select a Poa-free site
- In 1990/00, none of the herbicides trialed gave significant yield improvement, unlike previous years
- Best control of Poa was provided by ethofumesate (Norton, applied both pre- and post-emergence)
- Glyphosate may complement ethofumesate for Poa control if used while plants are very small, but may vary for each cultivar and locality
