• TNG

  • Proeftuin Zwaagdijk has had TNG approval (approval for the Use of Unauthorised Crop Protection Agents) since April 2011.

    Until 1 April 2011, field trials could only be conducted with unauthorised crop protection agents on the basis of a trial exemption from the Board for the Authorisation of Plant Protection Products and Biocides (Ctgb). As of 1 April 2011, the approval scheme (TNG approval) came into force, which meant that TNG-approved companies no longer require test exemptions for unauthorised crop protection agents.

    The approval scheme, like the trial exemption, is focused on field trials with crop protection agents which have not yet been authorised for use in the Netherlands.

     TNG approval (approval for the Use of Unauthorised Crop Protection Agents) relates to the safety of humans, animals and the environment when performing trials. The requirements are comparable to those for a trial exemption. In order to receive TNG approval, regulations need to be built into the quality system.

    TNG approval is awarded and monitored by NVWA.

    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. These involve looking at whether the procedures of the TNG approval are being followed. Proeftuin Zwaagdijk's TNG approval was extended for a further six years in 2015.
