Types of testing offered
The TPDDL can assist with any type of plant disease problem. Field crops, trees, turfgrass, vegetables, fruits, flowers, shrubs, houseplants, or any other type of plant is welcome. Lab tests are available for the detection of most plant pathogens. We can only test soil for nematode detection. For testing of most diseases of Upper Plains field crops, please contact the THPPDDL.

Specialized testing available
Please contact the TPDDL if there is need for specific testing of plant material for plant disease problems.

Turn-around time
Turn around time is dependent on specimen load that is received at the TPDDL. At peak time (spring-fall), routine diagnoses are usually finished in 11-21 days, depending on the test that is needed for the diagnosis. Specimens requiring extensive testing require more time. For example, oak wilt testing takes a minimum of 21 days. Diagnostic results are routinely emailed to the client, but results can also be faxed or mailed.
