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.


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