GMW bioscience performs high quality GEP efficacy and biostimulant studies for registration, product development and demonstration.

Efficacy studies are conducted in compliance with current European guidelines (EPPO) in Spain. Furthermore, specific national guidelines are also taken into account.

  • Effectiveness and selectivity trials with:
  • Insecticides and acaricides
  • Fungicides
  • Herbicides
  • Moluscicides
  • Growth regulators
  • Fertilizers
  • Soil disinfectants
  • Turfgrass trials
  • Ornamental plant studies

Appropriate site selection, considering climate and cropping regions as well as expected pest infestation levels are very important for the successful conduct of efficacy trials. Crop protection products are tested with natural or artificial infestation of the target pests. The trials are performed in our own experimental fields or in fields selected through our farming network. The following phases are normally carried out: trial set-up, application, assessment, harvest and reporting.

Study of unintentional effects PP 1/268 (3):

  • Field Phase
  • Analytic of wine
  • Organoleptic evaluation

This kind of trial is normally required for products containing active substances known to cause unintentional effects, or chemically similar to those known to cause unintentional effects on fermentation processes and wine characteristics. These trials are particularly needed in the case of residues with fungicidal activity occurring at harvest
