Weed sensing locations

To inform readers about weed sensing: the use of a machine or instrument to detect a weed; a plant that shouldn’t be there

Key messages
  • Optical Spray Technology (OST) systems are used for broad spectrum weed control for summer weed and fallow weed control. This type of sprayer is widely accepted in broad-acre cropping situations.
  • In-Crop weed detection is the sensing and identification of non-crop plants within the growing crop.
  • This technology is not as advanced, nor as widely used as the optical sprayer technology.
