**New** "SPN Packing Slip" webform

Please use this webform whenever you are submitting a plant sample for diagnosis so that we can document the contribution that public gardens are making to the knowledge about plant pests and diseases!

After completing the packing slip, you will probably also need to prepare a sample submission form from your state's diagnostic lab. These vary from state to state but you can use the following directory to find yours!
