When you are out at the club, dropping the bass is a good thing. When you are planting soybeans and have soil pathogen issues, dropping the base can be a bad thing. Why? See the new article posted on the Field Crop Disease Blog found by clicking here.…
This season we will be using a new system to monitor and track southern rust in Illinois #corn. We will be operating and managing a site that clientele can access and view in real time. I will provide information pertaining to the site once it is operational in a few days.
Why do we need to monitor rusts? Because rusts are obligate fungal pathogens. This means they need a living, green host to grow and reproduce. …
Each year our team of plant pathologists collaborate to develop efficacy tables for fungicides that can be used to help manage fungal diseases in field crops. Our most recent sheets can be found by clicking the following links:
CDWG Fungicide efficacy table_2019_final
Soybean Fungicide efficacy table_2019_final
These sheets will eventually be housed for download on the Illinois field Crop Disease Page along with factsheets, applied research data and guides, scouting videos,…

Most Illinois producers are behind in getting corn and soybeans into the ground this year as a result of persistent rains and cool temperatures. Some people are wondering what this might mean for some of the diseases we encounter in our field crops.
Keep in mind, disease occurs when you have the correct host, plant pathogen, and environment together. The longer those three factors are together, the more disease will occur. Although we cannot speculate much on the long term environmental conditions we will face this year and how that will impact diseases,…
