Submitting Digital Images for Diagnosis
Mobile app users: The mobile iOS and Google play apps for sample submission no longer work due to OS updates. The links above are mobile friendly for tablets.
- Normal sample handling fees apply to photos submitted for diagnosis ($11 from Indiana, $22 from outside Indiana). There is no additional fee for follow-up physical samples when needed for diagnosis.
- All photos submitted become the property of the PPDL and may be used for training purposes or publications.
General Digital Photo Tips
You can help us by following these guidelines:
- Please check your images before submitting them. If they look out of focus to you, they will not be helpful to us.
- Send up to 10 images per sample/question.
- When possible, please include a size reference such as a pen, ruler or a coin.
- For plant identifications, please include a photo of the whole plant, as well as close-ups of plant parts (leaves, flower, roots, fruit, seeds, etc.).
- As with actual samples, please include as much additional information as possible such as: planting date, age of plant, chemicals used, number of plants affected, where found, patterns, when symptoms were first noticed, etc.

We recommend, due to potential regional diferences in the occurrence of certain plant diseases, and species of plants and insects, that residents of other states first contact their local extension services and diagnostic labs for assistance, prior to submitting digital or physical samples to Purdue's Plant and Pest Diagnostic Lab (PPDL).
