A questionnaire for self-assessing barnyard grass resistance risk
- David Thornby
- Publication details:
- Barnyard grass plant
This questionnaire helps you to assess the risk of glyphosate resistance developing in awnless barnyard grass populations in your paddock or farm. It may give good results for other summer grasses, but we cannot guarantee its accuracy for other types of weeds.
As part of a weed management plan, you need to know the herbicide resistance status of key weeds, particularly in your high-risk paddocks.Consider having your weeds tested for glyphosate resistance if:
- paddocks are at risk of glyphosate resistance
- there are survivors of a glyphosate application.
