Virus Testing
Accurate detection of plant viruses for timely action
Virus Testing
Plant viruses require specialised diagnostic expertise. Virus Testing is performed by the Eurofins Agro Plant Doctors, who use methods such as ELISA, PCR and qPCR to identify viral infections early and reliably.
What is Virus Testing?
Virus Testing is a diagnostic analysis that identifies plant viruses in crop material, substrate and water. Each test begins with a visual assessment of the submitted material, followed by the most suitable laboratory techniques selected by the Plant Doctor.
The service supports growers, propagators and advisors in taking timely action to protect crop performance and prevent further spread of infection.
Why virus detection matters
Plant pathogens, including viruses, can cause a wide range of symptoms that often only become visible when damage is already significant. Early virus detection is essential to:
- Prevent avoidable yield loss
- Limit the spread of infection within or between crops
- Understand the true cause of unexplained crop issues
- Support targeted and effective crop protection strategies
- Reduce financial damage from late intervention
Accurate diagnosis makes it possible to act with confidence.
How Virus Testing works
Upon receiving the sample, the Plant Doctor evaluates the symptoms and information provided. Based on this assessment, additional analysis is selected, often using ELISA, PCR or qPCR for sensitive and specific virus detection.
Growers can also request testing for specific viruses. A selection of testable viruses is available upon request.
For samples shipped from outside the European Union, strict EU import guidelines apply. Plant material must follow these procedures to avoid delays or sample destruction by authorities.

When to use Virus Testing
Virus Testing is suitable when:
- Crops show unusual growth, discolouration or unexplained symptoms
- Viral infection is suspected in propagation or production
- Certification, export or import processes require virus status confirmation
- Other factors such as nutrition or climate do not explain crop decline
- Monitoring programmes include periodic virus screening
Timely testing helps protect crop quality and reduce economic risk.
Parameters analysed in Virus Testing
Virus Testing identifies plant viruses using validated diagnostic methods. Depending on the sample and symptoms, ELISA, PCR or qPCR is used to confirm whether viral pathogens are present and to support rapid action.
