Jo Anne Crouch is the Research Leader for the USDA-ARS Foreign Disease/Weed Science Research Unit (FDWSRU), located on the Fort Detrick U.S. Army installation in Frederick, MD. At the FDWSRU, Dr. Crouch leads a multidisciplinary team of scientists studying numerous foreign and newly emerging plant pathogens and weeds that pose threats to U.S. agriculture and the environment. The FDWSRU is the only USDA-ARS facility equipped to safely study hazardous plant pathogens requiring high containment at Biosafety Level 3. The FDWSRU’s unique science and technology base serves not only to address current threats to U.S. agriculture, but is also an essential element in the response to any future biological threats posed by foreign plant pathogens.

Dr. Crouch is also serving as the Acting Research Leader of the USDA-ARS Beneficial Insects Introduction Research Unit (BIIRL). The BIIRL conducts research to help manage invasive insect pests by introducing effective natural enemies from the pest’s native range. This approach (classical or introduction biological control) can lead to permanent reductions in pest populations.

Research Emphasis

Identify genotypes, variants & species limits of high consequence foreign pathogens of U.S. agriculture; and develop identification resources for fungi and oomycete plant pathogens, including diagnostic assays, molecular datasets, barcoding tools, & molecular phylogenies. Current research projects in the lab are focused on pathogens that cause downy mildew diseases of cereals & grasses, fungal pathogens of corn and other cereal crops, boxwood blight, and foreign oak wilt diseases.
