A Danish invention has found a way to reduce the use of pesticides in agriculture by as much as 95 percent, the engineering publication Ingeniøren reports.
Morten Stigaard Laursen developed the invention as part of his PhD project at the University of Southern Denmark. It uses a camera connected to a computer programmed with a patented algorithm to differentiate between weeds and crops.
Laursen explained that the system functions by targeting the application of chemicals instead of spraying them over all crops at the same rate.
