Key Messages
- UAV imagery with skilled specialist analysis and programs has the potential to identify and map weed issues in paddocks.
- Grass weed patches are easier to identify in legume and pasture crops than cereal crops.
- Variability in germination and crop growth makes it harder to identify grass weed areas.
- Data capture and analysis for analytical purposes such as grass weed mapping in individual paddocks will be beyond most farm businesses unless farmers have a special interest in this area.
- Group A resistant barley grass has once again been detected at the Minnipa Agricultural Centre. Barley grass resistance to Group A herbicides has been detected 3 times in 3 years, so be aware it is in current farming systems.
