- Fertile plant material (potato tuber) has to be transported and stored in closed and clearly labelled repositories at any time outside the release site and laboratory. The label need to distinctively describe the LMO and it needs to be noted that this potato is unfit for consumption. All remaining fertile plant material has to be destroyed by disruption of their germination capacity (heating or autoclaving).
- Transgenic and non transgenic potatoes have to be stored separately.
- Inspection of release site on unexpected biological traits of the LMO and reciprocal effects between LMO and other organisms has to be accomplished weekly during the experimental release. Particularly it needs to be observed whether the development of the potato plants (from seedling to dead plant) proceeds comparable to wild-type plants and whether habitus, blossom colour and potato berries look as on wild-type plants.
- Monthly inspection of the surrounding area [20 m] of the release site for transgenic potato volunteers and their manual removal and disposal.
- After harvest the first 15-20 cm of upper soil of the release site have to be loosen up. Potato tubers that emerge during that procedure have to be manually collected, removed, and destroyed by disruption of their germination capacity. The release site must not be ploughed.
- After completion of the field trial monthly inspection of release site and surrounding areas [20 m] for transgenic potato volunteers, their documentation and removal and disposal has to be accomplished for one year. The inspection period has to be extended for another year if potato volunteers were observed. The release site must not be cultivated with plants impairing the detection of transgenic volunteers. 
- The release site has to be labeled with a sign noting „trial crops, unfit for consumption“.
