Invention Summary   camera

Scientists at NDSU have developed a method for determining the glyphosate sensitivity of plants in a plot comprising obtaining a thermal image of the plot to determine the amount of heat emission at a time after application of glyphosate and correlating the heat emission to the level of glyphosate sensitivity. Combined with visible imaging, the species identification of the weeds as well as their response to glyphosate treatment can be determined. The method allows determination of glyphosate susceptibility much earlier than visual determination of actual glyphosate injury to the weeds. Imaging can be completed using unmanned aerial systems (UAS) for rapid and frequent determination of the glyphosate effect, diagnosis and retreatment.

Benefits

  • Allows earlier detection of glyphosate susceptibility in a plot than visual inspection
  • Simultaneously allows weed species identification and glyphosate susceptibility of the different species 
  • Allows aerial imaging to avoid physical injury to crops
  • Identifies
