Laboratory testing

Every entrepreneur wants to be able to supply their customers with healthy material. Naktuinbouw tests seeds, plants and trees for health and quality.

Testing provides an indication of the quality of propagating material. Naktuinbouw’s laboratories test propagating material for the presence of harmful viruses, fungi, bacteria, nematodes or other organisms. With its wide-ranging expertise and high-tech equipment, Naktuinbouw offers you the certainty of working with properly tested propagating material.

To ensure that we perform our tests in accordance with the latest international guidelines, we work at various levels with a range of organisations such as the NVWA (Dutch Food and Consumer Product Safety Authority), EPPO (the European and Mediterranean Plant Protection Organisation), ISTA (the International Seed Testing Association) and ISHI (the International Seed Health Initiative).

We only share the results of the tests with the customer. We are only required to notify the NVWA if we find a quarantine organism.

Our laboratories' services are available to all. Your company does not have to be registered as a customer of Naktuinbouw.
