• GEP research NL

  • Since June 1997, Proeftuin Zwaagdijk has been GEP-certified. GEP (Good Experimental Practice) is a quality system designed to ensure the proper implementation of effectiveness studies for crop protection agents. The GEP certificate issued by the Netherlands Food and Consumer Product Safety Authority (NVWA) entitles Proeftuin Zwaagdijk to perform effectiveness studies. These studies carried out under GEP, which involve looking at the effectiveness and/or selectivity of a crop protection agent, are compulsory for the authorisation of crop protection agents.
    The goal of the GEP certificate is to guarantee that tests are of a high quality and are performed harmoniously. The tests must be carried out in accordance with European (EPPO) guidelines. All tests in Europe are performed in accordance with these guidelines. 
    In 2015 NVWA inspected our procedures, equipment, HR dossiers and records extensively. These inspections are held once every six years. Besides the major inspections, NVWA annually performs 6-8 inspections while trials are being conducted. For example, they look at whether the trial has been planted in accordance with the procedures and whether spraying and evaluation are being conducted in accordance with the procedures. Proeftuin Zwaagdijk's GEP certificate was extended for a further six years in 2015.
