The University of Maryland Plant Diagnostic Laboratory

 The Plant Diagnostic Laboratory provides plant problem diagnosis for all crops. Most diagnoses are based on microscopic examination of the specimen and visual identification or culture of plant pathogens such as fungi, bacteria and nematodes. Identifications of plants, insects and mites attacking plants are also performed. Some specimens are referred to specialists in other departments or other institutions for diagnosis.
