Samples must be submitted fresh and should be collected and shipped no later than Tuesday using an overnight delivery service.
Try to collect samples that are representative of the range of symptoms and stages of disease observed in the field. Tissue must still be living to be used for testing, no senescing, dead or decayed material.
Select 5 leaves of green or living tissue closest to the symptoms, try to collect from different parts of the affected plant to account for any uneven distribution of the pathogen.
Use new Ziploc sandwich or vegetable bags to collect your samples to avoid any cross-contamination of the sample. Do not mix different samples in the same submission bag and label the sample number (e.g., #1, #2, #3, etc.) clearly on the bottom right corner of the bag with indelible marker to identify each separate sample.
Organize your samples consecutively into groups of 10-20 bags (e.g., Samples #1-20, Samples #21-40, etc.) by using 1 staple or clip on the top left corner to secure each group. This ensures that the samples arrive in the order that they will be tested and can be processed without further delay. Please do not throw loose sample bags in random order into a box for shipping. Number and label your samples clearly and secure them in order to ensure that all samples can be identified and accounted for accurately.
Include a Sample Submission Form with your samples. Please take the time to write clearly or type the information, you can also email us a copy to let us know what samples will be arriving. If we cannot read it to identify the sample we cannot record or test it.
BC blueberry growers can submit up to a maximum of 30 samples free of charge for Blueberry Scorch Virus (BlScV) and Blueberry Shock Virus (BlShV) testing, funded by the BC Blueberry Council for the 2022 testing year. BC blueberry growers should use the 2022 BCBC Sample Submission Form (also found at the top of the page) when submitting their samples to qualify for the testing available. Program specific instructions for sample submission are included on the form.
Note any information that may be pertinent to diagnosis such as a description of the symptoms, growth conditions, pesticide use, insect vectors that may be present, or anything else you think might be important. Record this information and any additional information, such as plant location, on the Sample Submission Form instead of on the sample bags, as the sample bags will be discarded during testing.
Pictures of observed symptoms can also be emailed. Provide a description of what the picture is depicting and ensure it is in focus and of sufficient quality.
If you are unable to ship your samples directly after collection, store them at 4°C, taking care not to freeze or expose them to heat.
Keep tissue samples dry by avoiding collection in the rain and/or including paper towel to soak up excess moisture and/or using ventilated bags (e.g., vegetable Ziploc bags or perforated bags). Please do not ship moist samples in airtight bags; samples that have decayed in transit cannot be used for testing.
Include a Sample Submission Form that includes sample identification, collection date, the name and initial of the person who collected the sample, tests required and any pertinent information regarding the sample. Please write clearly or type the information.
BC blueberry growers submitting samples for BlScV and BlShV should use the 2022 BCBC Sample Submission Form (also available at the top of the page) to qualify for the 30 free samples available under the BCBC funded program.
Package and ship samples carefully to avoid deterioration in transit, making sure to limit the amount of moisture the sample is exposed to.
Protect against crushing, freezing or overheating by packaging your samples securely. Do not enclose an icepack with your samples, often it will cause degradation of the sample by either freezing or crushing the tissues in transit.
Use an overnight delivery service to maintain sample integrity, especially when shipping perishable samples that may be destroyed in transit by exposure to prolonged shipping time and extreme hot or cold temperatures.
Ship early in the week (no later than Tuesday) to avoid having perishable samples sit over weekends or holidays. Samples that do not arrive fresh and in good condition cannot be used for testing and will have to be resubmitted.
Contact us by phone or email to let us know your samples will be arriving to minimize any processing delays.
