WEST LAFAYETTE, Ind. — Farmers, homeowners, greenhouse and
nursery growers, agricultural specialists and others who need to identify
plants, plant diseases, insect pests and other plant problems have a new mobile
application resource created by eight university labs, including Purdue’s Plant
and Pest Diagnostic Laboratory.

built-in mail app, which requires an email account on the device.
PPDL will charge normal sample-handling fees for samples
submitted through the app. Those fees are $11 for Indiana samples and $22 for
out-of-state submissions. However, if a physical sample is needed as a
follow-up, there is no additional fee.
Each of the other diagnostic labs has specific fee policies,
so users should check with their preferred lab for details.
The PPDL accepts submissions from the 48 contiguous states.
International submissions are not accepted. Right now Kentucky and New Hampshire
laboratories will only accept samples via the app from Extension educators and
specialists who have a proper passcode.
The app is available for free download in the iTunes store.
