- The specification of the exact release site.
- Fertile plant material has to be stored in closed and clearly labelled repositories for transport and storage at any time outside the release site and laboratory.
- Inspection of release site on unexpected biological traits of the LMO and on reciprocal effects between LMO and other organisms has to be accomplished weekly during the experimental release and monthly after the experimental release.
- Monthly inspection of the surrounding area (10 m) of the release site for transgenic petunia volunteers and their removal and disposal.
- After completion of the field trial, monthly inspection of the release site and surrounding area (10 m) for transgenic petunia volunteers, their documentation and removal and disposal has to be accomplished for one year or longer if volunteers were observed. No plant species must be cultivated on the release site that impairs the detection of transgenic petunia volunteers.
- After completion of the field trial an appropriate land management via harrowing and grubbing is intended to support fast germination of seeds so that transgenic petunia volunteers can be easily destroyed by application of an herbicide.
- If any new information on the cultivated LMO emerges that might bear any risk for human health, animal health or the environment the national federal authority needs to be informed and sufficient risk measures have to be performed.
