I want to remind you of a few resources for monitoring field crop diseases here in Indiana as planting has begun to ramp up here in Indiana. Our team will be tracking diseases across Indiana and will add updates here in Pest & Crop and on the Purdue Field Crop Pathology Extension site. You can also follow me on Twitter @DTelenko
There are national field crop pathology programs in place to track and/or predict risk 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; and soybean rust. The Crop Protection Network site hosts unbiased, 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.
