More effective and reduced pesticide use in broad acre landscapes by using optical sensing devices to detect and “spot spray” weeds” locations
Aims
  • To evaluate the suitability of "spot spray" technology to control weeds on farming land in the Upper North.
  • To monitor weed control success on "hard to control" summer weeds such as fleabane, onion weed, saltbush type weeds.
  • To record the reduction in pesticide and water use using "spot spray" technology compared to conventional spraying.
  • To raise awareness amongst the community about the potential benefits of "spot spray" technology.
Key messages
  • Summer weed control is proven to increase yield, but is becoming a major cost and some summer weeds are difficult to control.
  • Cost savings of 20-90% were achieved across 20 paddocks using the WEEDit™.
  • A major benefit of the Spot Spray Technology was the ability to use high rates of chemical to spot spray hard-to-kill weeds such as fleabane and stinkweed.
