Test Centre in Horst

The staff at the Test Centre are at your disposal to make your material virus-free, maintain it or perform bioassays on it.

Making material virus-free

The team at the Test Centre in Horst make woody plants such as apple, pear, strawberry, raspberry and rose, as well as ornamental trees, virus-free using heat treatment. The tops of treated plants are grafted onto virus-free rootstock or cuttings are produced. A range of tests is then performed to confirm the virus-free status of the grafted tops.


Because we maintain material, we can supply you with new grafting material, softwood cuttings or plant material.


We can detect any viruses that may be present by means of sap inoculations on herbaceous indicators.
