The high number of prevented-planting fields in some areas, the late start to harvest, and the inability to apply P and K fertilizer as planned last fall or this past spring combine to raise a number of questions about fall application of P, K, and lime over the next few months.
Prevented-planting fields
If P and K fertilizers were applied last fall or this past spring but no crop could be planted, there’s no reason not to count all of the applied P and K as available for the 2020 crop.…

After the worst start to a cropping season in decades, mid-season lack of rain in parts of Illinois, and season-long low crop ratings, it’s time to take a look at what comes next as the 2019 cropping season moves into its final stages.
Corn
To no one’s surprise, various crop tours in recent weeks have confirmed that corn yields in parts of Illinois are likely to be disappointing. If there is a positive, it’s that the crop may look a little better than we thought it would by now after more than half of it was planted after June 1.…

There are two, fairly new and / or important diseases  to keep an eye out for in 2019.  We are actively seeking samples of symptomatic plants for research to help us understand the biology, ecology, and management of these pathogens.  If you have a suspect sample, please send to the UIUC plant diagnostic clinic for confirmation (cost will be covered), and or contact me via email, telephone, or twitter.
 
The first is a disease that we started working on in late 2017- Tar spot on corn. …

The 2019 Illinois corn crop reached 50% planted during the first week of June, more than a month later than the average of the past five years. The soybean crop reached 50% planted a few days later than corn, and more than three weeks later than the average of the past five years. May rainfall was above normal over most of Illinois, and June brought near-normal rainfall over much of the state. Still, the late planting coupled with too much or too little rainfall after planting produced July crop condition ratings of only about 40% good + excellent for both crops,…
