There are a number of resources available for monitoring field crop diseases here in Indiana. The Purdue Field Crop Pathology Team will be tracking diseases across Indiana and will post updates here and in Pest & Crop. You can also follow me on Twitter @DTelenko
National disease tracking and prediction programs are place to monitor for some the more economically important diseases in the Unites States, such as Fusarium head blight in wheat, wheat stripe rust, southern rust of corn, and tar spot. In addition, the Crop Protection Network site hosts collaborative outputs on important issues affecting field crops in the United States and Canada, this site has numerous resources and fungicide efficacy tables for corn, soybean, and wheat.
