How to send a sample to the Schutter Diagnostic Lab (it's really just 4 steps):
Useful Submission Links
- Keep samples as fresh as possible.
- Avoid exposing samples to direct sunlight and refrigerate if possible.
- Send sufficient plant material.
- Collect samples that show various stages of the problem and include a healthy plant or plant part for comparison.
- Whenever it is practical, include roots or the entire plant or a clump of plants. If that is not possible, include a branch or send a twig. Detached leaves or parts of leaves are seldom useful.
- Avoid sending dead plants or plant parts, they are not useful for accurate diagnosis.
- Package samples in crush-proof containers.
- Never send samples in a flat paper envelope – the post office machinery causes extensive damage.
- If you are sending a plant that includes roots, keep some soil around the root ball
and off foliage.
- Wrap the root ball in plastic and secure with a rubber band around the base of the plant (figure 1). This prevents the soil from damaging the leaves during shipping.
- Loosely enclose the foliage in plastic or paper.
- Do not add water or wet paper towels to sample submissions.
Considerations for when and how to ship a sample to the Schutter Diagnostic Lab:
Our mailing address and contact information are listed at the bottom of the page.
- Samples can be dropped off. The Schutter Diagnostic Lab is normally open for walk-in submissions from 9:00AM to 12:00PM, Monday through Friday (COVID-19 restrictions currently apply).
Mail packages early in the week to arrive by Friday.
Do not mail fresh samples on a Thursday (unless using overnight mail) or Friday. Store the package in the refrigerator over the weekend and mail on Monday. We want to avoid samples sitting at the post office over the weekend.
- Include completed sample submission form with pertinent background information.
- In-depth background information will help us identify the problem or organism and is essential for timely management recommendations. Details allow us to provide more accurate diagnoses.
Include photographs illustrating the problem if possible.
Make sure photos are in-focus.
Email photographs to firstname.lastname@example.org. Include your name, contact information, and the date your sample was shipped.
We are open for walk-in clients from 9:00AM to 12:00PM, Monday through Friday (COVID-19 restrictions apply).
