About us

The Diagnostic and Advisory Service can receive and examine plant material in order to provide a diagnosis with regard to plant health problems. Service personnel have specific expertise in problems related to fungal and bacterial pathogens as well as nematodes. Through linkages with other UK organisations, including Fera Science Limited, we can also assist with problems related to viruses, phytoplasmas and insects. The Service can provide authoritative identification of organisms associated with or isolated from symptomatic plant material and for individual specimens and cultures provided by a client. The service is unique in its global operation and the range of plant diseases it can handle, and is well placed to diagnose and advise on problems of temperate and tropical crops in particular.

The Diagnostic and Advisory Service team, using their extensive international experience and expertise, can also offer professional and practical advice on prevention and management of specific plant health problems based on interpretation and application of diagnostic results. In doing so, they can draw on a wealth of information accessible from the Plantwise Knowledge Bank and CABI's award winning Crop Protection Compendium

As a component of the Plantwise programme, the Diagnostic and Advisory Service is supported by a number of funding agencies, enabling us to provide a free service to eligible groups under some circumstances
