The Digitally Assisted Diagnosis area provides a standard method of submitting digital samples to the P&PDL for diagnosis or ID. Digital samples submitted to the Plant and Pest Diagnostic Lab are assessed the same $11 (in-state) and $22 (out-of-state) charge as physical samples. 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 (P&PDL). Follow this link for Plant Disease and Soil Testing Services located in the United States. There will be no additional charge for any related follow-up physical samples that might be requested by diagnosticians who require more detail for an accurate identification or diagnosis of the problem than is provided by the digital images submitted.
