Instructions for sample submission:
The accuracy of testing for plant pathogens depends upon the quality of a plant sample submitted for analysis. Please follow these guidelines (in general) for collecting and submitting a sample to the MDL.
- Submit freshly collected specimens showing the range of symptoms that you observe.
- Provide adequate amounts of plant materials, including roots, top growth, and fruit (if available).
- Try not to send dead plant material and keep samples refrigerated after collection until they are submitted.
- Complete submission form and provide as much information as possible about the sample.
- Place the specimens in a plastic bag and clearly label the outside of each bag with a permanent marker. For leaf or stem tissue, place the sample in a zip-seal bag as soon as it is collected. Send samples via overnight delivery.
- If you include multiple bags in a package, clearly indicate whether each bag corresponds to a separate test, or whether the bags simply represent multiple samples for the same test.
- To prevent damage during transit, use cardboard boxes and add packing material such as newspaper. Do not use paper bags.
- Make sure you submit the respective diagnostic fee (payable check to MDL).
