We provide the efficacy trials for your biological assessment dossier. The protocol is designed with the inclusion of your specific requests. We select trial sites with adequate pest/pathogen occurrence or artificially infest/infect the crop. Trials are organized and performed at external quarantine greenhouse compartments for target organisms with a quarantine status.

Research questions for these trials can be about dose-finding, comparison of different application types, timings and spraying techniques. Our experts help you with defining a practice-relevant reference spray schedule.

Randomized block designs are sprayed with an automated RTK-GPS-steered tractor-mounted sprayer for outdoor crops. This in-house designed solution reservoir from which the machine automatically selects the right one to spray a specific plot, following the trial map.

Phytotoxicity and selectivity

The phytotoxicity of a product can be investigated (GEP), either combined in an efficacy trial or specific crop safety trials.

List of application techniques (non-exhaustive):

  • Spray application
  • Aerosol
  • Pouring
  • Handling of treated seeds
  • Seed treatment (e.g. Phyto-Drip)
  • Granulates
  • Infection with viruses
  • Soil injection
  • Drip irrigation
  • Drench
  • Dip
