Be sure to use a clean tissue sampling bag to prevent skewing the sample results. a. A plastic pail or a paper bag work best. Never use a metal container to gather the sample as the metal may contaminate the sample. 4. Clean your hands before taking a sample to make sure you are not transferring contaminates to the plant. 5. Collect approximately one pint of lightly packed plant tissue. A pair of scissors is helpful for the process. Do not include roots. 6. Clean the sample to remove soil, fertilizer, dust, or spray residue. A dry brush works well. For stubborn residues, wipe the samples with a damp cloth or wash the samples with distilled or deionized water. Do not prolong the washing. Air-dry the samples if wet. 7. Place the cleaned plant tissue collected from one plant into one clean paper sampling bag. 8. At the office, update the work order. Make sure Sample ID and crop development stage have been accurately recorded and updated in the online software. Once completed, submit sample work order to lab, and print the submittal form. 9. Pack and ship samples and their corresponding submittal forms to the lab as early in the day as possible. Multiple sample bags can be packed in a shipping box. All samples must have the submittal form included when shipped.
