Eurofins-GAB performs a wide range of efficacy studies (GEP) for registration, product development and demonstration. Trials are carried out by our own staff in UK, Northern and Southern France, Northern and Southern Germany, the Netherlands, Denmark, Poland, Hungary, Spain, Portugal, Italy and Greece. We provide representative climates and cropping regions. Our knowledge of national requirements and of the local occurrence of weeds, pests and diseases provides an ideal basis for successful trials.
