Lupin and annual ryegrass locations
Aims

To provide growers with the tools needed to adopt site-specific weed management (SSWM) strategies as a result of a commercially viable weed ID and mapping system being demonstrated.

Key messages
  • Commercial viability has been difficult to demonstrate.
  • Field trials demonstrated that the H Senor was able to accurately classify annual ryegrass in several broadleaf crops, including canola, faba bean, lentil and field pea.
  • Other grass weeds such as brome grass and wild oats were also correctly identified as grasses in these crops.
  • Broad leaf weeds were accurately classified in cereal crops, however this was more difficult due to the overlapping nature of the cereal crops at the time when the broadleaf weeds had emerged.
  • Classification accuracy was lower for detection of grass weeds in cereal crops and broadleaf weeds in broadleaf crops, and these scenarios were not pursued for that reason.
