The fee for plant disease diagnosis is $10 and should be included with the plant sample and a completed Plant Disease Identification Form, PD 31. Detailed background information and a representative sample are important for an accurate laboratory diagnosis. A representative sample shows a range of symptoms, from early symptoms to advanced symptoms. Pictures of the overall symptoms and site conditions are very helpful in diagnosing plant health problems.

Details on how to collect an adequate sample for diagnosis can be found in the Iowa State University Extension publication PM-1542 Tips for Providing Insect and Disease Samples to ISU. The Plant Disease Identification Form (PD-31) is available online.
