My research is focused on the management of fungal foliar pathogens affecting carrot.  Both Alternaria dauci and Cercospora carotae are characterized by dark lesions on carrot leaves, often rendering them indistinguishable in the field.  As these diseases progress, lesions connect and girdle the leaves, sometimes destroying the entire canopy.  Michigan commercial carrots are mechanically harvested, but when the canopy is significantly damaged by A. dauci or C. carotae, the top lifting harvesters are unable to grip leaves and pull carrots from the ground.  This results in a yield reduction and potential source of pathogen inoculum for the following year.  I aim to give carrot growers more information on how to control Alternaria leaf blight and Cercospora leaf spot.
