That was one heck of a storm yesterday. Many fields throughout East central Illinois were severely affected by nickel sized hail. Although my three year old stated that we should, “use some tape” to fix the damaged tissues, some will consider fungicide applications. A new post on the subject can be found here.
Wheat development in most in Southern Illinois fields is between Feekes growth stage (FGS) 9-10.5.1. Wheat in the central portion of the stage varies from FGS 6-9.
Stripe rust was detected in Eastern Madison County as of 5.5.20, and conditions are favorable for disease development and spread. This is a cool season disease that loves wet weather and temperatures in the high 40’s through the mid 60’s. Fields should be scouted for the disease, keeping in mind that it often starts in small pockets, or epicenters in a field, and may not be widespread.
Remember that products for head blight suppression also work on stripe rust (example for a late-arriving epidemic below). If disease arrives prior to heading on a susceptible variety, you may need to consider
Wet weather is elevating the Fusarium head blight (FHB) risk for highly susceptible , flowering wheat. Cool temperatures in the forecast may reduce FHB risk for flowering wheat in many areas. For an update on Fusarium head blight click here.

That’s right, we have a new post on the Illinois Field crop Disease Hub! The topic today- considerations for planting poor quality soybean seed. click here to access the link!
There are many diseases that can impact Illinois #corn production, and several are caused by pathogens that impact the foliage. When foliage is damaged by pathogens, carbon and nutrient delivery to developing/filling grain can be reduced, limiting yields. Examples of foliar diseases include grey leaf spot, northern corn leaf blight, southern and common rust, Diplodia leaf streak, bacterial leaf streak, Goss’s wilt, and tar spot. Which foliar disease is the biggest issue for you?

The 2020 fungicide efficacy tables for corn and soybean are now available on the Illinois Field Crop disease hub. Click this link for more information.
We have posted some new materials (along with cool visual aids) on basics of integrated disease management. Hopefully this information will be useful to you during this busy meeting season. Click here to view this post.

With meeting season going full blast, you will be seeing a slew of data pertaining to disease management and the efficacy of various disease management products. We posted some general tips to keep in mind at the Illinois Field Crop Disease Hub that can be viewed HERE.

The 2019 edition of our annual report on applied research in field crop disease and insect management can be downloaded at the following link: https://uofi.box.com/v/2019PestPathogenARB
Each year, University of Illinois plant pathologists and entomologists produce a summary of the applied research we have conducted to inform disease and insect management practices in Illinois. This information provides a non-biased, third-party evaluation of control tactics such as pesticides and resistant varieties for use in corn, soybean, and wheat.
The 2019 report includes information on the following topics:
- Surveys of insect pests and soybean cyst nematodes
- Control evaluations for diseases of corn, soybean, and wheat (including southern rust, tar spot, fusarium head blight, and more)
- Evaluations of Bt trait packages and soil insecticides in corn and foliar insecticides in soybean (including western corn rootworm, bean leaf beetle, dectes stem borer, and others)
