Plant Pest Diagnostic Center
The Plant and Pest Diagnostic Center is a diagnostic laboratory whose services are provided by the University of Tennessee Agricultural Extension Service. The center is located in Nashville, with six Extension specialists onsite at the facility. Other specialists are available in Knoxville and Jackson to assist in difficult diagnoses. Services include plant problem diagnosis, insect and weed identification, fescue endophyte testing and nematode analysis. Other tests are conducted on a seasonal basis, such as plant virus testing.
It is requested that all specimens be forwarded to the diagnostic laboratory through the local county Extension agent. Often an identification can be made at the local level, resulting in faster response to the grower. After a diagnosis is made, the form (minus the lab copy) will be returned to the county agent. The county agent can evaluate the laboratory diagnosis and make any changes or additions that are necessary before the grower copy is returned. All county Extension offices have a supply of mailing materials and appropriate specimen forms. Additional forms and mailing materials can be provided to the county offices by the Plant and Pest Diagnostic Center.
Distance Diagnostics Project
The Distance Diagnostics Project was designed to rapidly transmit images of pest problems and related information to the Plant Pest Diagnostic Laboratory located in Nashville, TN. The objective of this system is to improve the diagnostic response time, therefore improving crop sustainability while promoting best management and integrated pest management practices for clientele in Tennessee.
This project enhancement was initiated due to the nature of insects, plant diseases and weeds which have the ability to rapidly multiply and where immediate control is essential in order to reduce economic losses. Distance Diagnostics enhances the Plant Pest Diagnostic Center’s system in which samples are sent via mail. By using web based imaging and informational test format, specimens can be rapidly diagnosed. This system will also provide a pest imaging library which can be used for research and teaching.
