In precision plant protection, the target of the spray liquid is not the area („per hectare“), to which the indication of the application rate on the package insert of a pesticide is referring to, but the weed or crop plants that must be coated by the spray liquid. Pests and weeds occur in a nest structure in crop plants. Therefore, during research works, the spraying amount is adjusted according to the local pest and crop plant parameters detected by the sensors. In comparison to a conventional uniform application, the use of pesticides is thereby reduced.

Current research

  • How can the target oriented crop protection reduce the use of pesticides?
  • Which sensor technology can automatically detect crop diseases and competitors during traverse?
  • Which sensor-supported techniques can adjust the spraying amount during application, in accordance to the locally changing parameters of crop plants and pests? And what savings of pesticide use can be achieved?
  • How can we detect the crop plant condition (pest- and drought stress-induced leaf death) within crop formations with the new optoelectronic vertical sensor?
  • With which sensor-based monitoring strategies can we identify and register invasive species, e.g. common ragweed, which is dangerous for people with pollen allergy?

Ongoing research projects

  • Precise application of pesticides
  • Multi- and hyperspectral image processing for the ascertainment of plant characteristics
  • Image analysis for plant phenotyping
  • Optoelectronic sensors for the recording of inventory parameters (biomass, leaf area) 

  • Project FungiDetect: Sensor-supported online detection of pests in grain
