The Plant Disease Diagnostics Clinic (PDDC) at the University of Wisconsin-Madison provides disease identification and control recommendations for agricultural producers and agribusinesses in the state of Wisconsin. In 2000, approximately 8% of the PDDC’s samples were field and forage crop samples, including field corn, soybeans, and alfalfa. Heavy rains in May and June provided ideal conditions for the development of a variety of field and forage crop diseases.
