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 detections of most plant pathogens. Tissue isolations are commonly used to detect fungal and bacterial plant pathogens.
State-of-the-art diagnostic techniques such as fatty acid methyl ester fingerprinting for plant bacterial pathogens identification and real-time PCR detections of pathogens are routinely used in the TPDDL.
Detection of plant viruses, using serological techniques, is also available. The TPDDL is capable of testing of both soil and plant roots for plant parasitic nematodes.
The TPDDL offers specialized testing for the the oak wilt pathogen (minimum 21 days), Pierce’s Disease of grape, and Citrus Greening. Please contact TPDDL if there is need for additional specific testing of plant material for plant disease problems.
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 7-10 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.
