Where can I find out how big my seed sample needs to be?
You can find this in the Price list Laboratories 2021 on our website behind the relevant button.
Where can I find out which tests you can perform on my crop?
You will find our current portfolio in the Price list Laboratories 2021 . For vegetable crops, which tests we can perform is stated per crop. For plant material, a separate chapter lists which tests are available.
Do you have any questions?
Please contact the Support team of the laboratory: firstname.lastname@example.org.
Can I also have tissue propagation material tested for pathogens?
All our tests have been validated on in-vivo material. Depending on the testing technique used, in-vitro material can also be tested. The PCR technique is very sensitive and can generally be used. The ELISA technique is less robust and is not recommended. Preferably have the propagating material tested. Alternatively, again later when the plants have been in the greenhouse for a few weeks.
What type of material do I need for virus testing on plant material?
Virus testing requires young, fully-grown leaves.
Where can I find out which plant material I should have tested for various pathogens?
You can find this in the price list [link] on our website under the desired test.
What is the difference between disinfected and treated seeds?
- Disinfected seeds carry residues to a greater or lesser extent. The most obvious example is seeds coated with crop protection agents. The aim is to remove as much fungi and / or bacteria from the seeds as possible. These products may potentially influence the tests.
- Treated (disinfected) seeds do not contain any residues. Examples include warm water treatment or treatment with TSP or HCl. These products are not expected to affect the tests.
Can I also have disinfected/coated seeds tested?
Seed tests have been developed and validated for untreated seeds. Seed treatments can affect the reliability of the health test results. For this reason, preferably submit untreated seed samples.
If the tests explicitly state that the test will be performed on treated seed, please submit treated seed. Please state with the order with which agent the seeds have been treated.
Can I also have primed seeds tested?
Seed tests have been developed and validated for untreated seeds. Seed treatments can affect the reliability of the health test results. For this reason, preferably submit untreated seed samples. Certainly for tests that are carried out using a cultivation method. During the priming process, there is a strong increase in the number of micro-organisms in the seed. Even after additional disinfection after priming, no assessable results can be obtained. This is because the additional micro-organisms from the seed cause too much interference in the test.
How do I know how many plants I should sample for export?
For export, an inspector often arranges the sampling. You can send an email to email@example.com. They can tell you exactly what you need to do.
Can samples disinfected with Thiram be sent in for laboratory testing?
We are only allowed to receive and test the samples if seed lots have been treated with Thiram and are going to countries outside the EU.
Can samples be returned?
Samples intended for health tests cannot be returned. First of all, these samples are tested destructively. After testing, the samples are no longer usable. Secondly, they are in a contained area. The samples are not allowed to leave this area.
