Research Focus:

       Sugarbeet is the source of more than half of the domestic sugar that is produced in the United States providing the U.S. with a viable domestic sweetener industry that produces an annual estimated $262.2 billion.  Importantly, sugarbeet is the most valuable crop in crop rotations in many growing areas of the United States and plant diseases remain an important source of crop and sugar losses throughout these growing regions. Thus, it is essential to continue to understand and develop improved disease resistance in sugarbeet in order to minimize losses in economic potential.

      The plant pathology program is responsible for characterizing the interaction of major sugar beet pathogens (i.e. Cercospora beticola, Rhizoctonia solani, and Fusarium oxysporum) with sugar beet in order to provide new information that will facilitate the development of improved sugar beet germplasm with greater disease resistance and assist in the development of innovative management principles.  Using applied, biochemical, and molecular technologies we try to describe how sugarbeet pathogens cause disease, in the hope that novel pathways may be developed to better control those pathogens.  A second focus of the project is to determine the genetic relationship and spatial scale of the pathogen populations that affect sugarbeet, in order to more fully understand the disease interactions and how they may differ throughout the many production regions.
