If the appearance of the soybean crop going into late July predicts how it will yield, the 2018 crop in Illinois is going to be a high-yielding one. The crop in Illinois was rated at 78% good + excellent (G+E) as of July 22. Conditions across the US soybean growing regions are somewhat variable, but the 2018 crop is in good condition overall.
As I did with corn in the Bulletin on July 6,…
This week there has been a slight uptick in the amount of foliar disease reports in corn, likely as many people are actively scouting prior to making a fungicide application decision. The most common disease, as you may expect is Grey leaf spot. This disease is present to varying degrees in most fields. No big surprise there.
We have seen and received several reports and samples of Diplodia leaf streak. This disease can be caused by two different species of Diplodia,…
It is proving to be a big year for Japanese beetles in Illinois, and while populations should be starting to decline in much of the state, there is still a lot of feeding going on. The damage these insects cause can be eye-catching, especially on the edges of fields where Japanese beetles tend to congregate; however, before you decide to put out an insecticide, you want to be sure that decision is justified by the economics of the system.…
The University of Illinois Extension will host the Ewing Demonstration Center Agronomy Field Day on Thursday, July 26, 2018 at 9 a.m. Every growing season presents challenges to production, and this year is no exception! We are happy to host this summer field day to share with local growers current, ongoing agronomy research in southern Illinois, including cover crop trials on corn and soybeans, nitrogen management in corn, weed management in soybean, and our continuous no-till field,…
The crop progress report from NASS showed that on July 1, 40 percent of the Illinois corn crop was silking, the crop rating was 85 percent good + excellent (G + E), and more than 85 percent of Illinois was reported as having adequate or surplus soil moisture. While this combination is very supportive of prospects for high yields, questions remain about whether the crop is actually as good as it looks, and about how dry weather in the coming weeks might affect crop prospects.…

White mold, caused by Sclerotinia sclerotiorum, is one of the most problematic diseases impacting soybean production in the northern portion of Illinois. Fungicides can be used to suppress this disease; however, the optimal timing for fungicide application, or the need for a fungicide application,…
We are at that time in the season where many people will be making final decisions regarding fungicide applications in soybeans and corn. I wrote an article with tips and other items to consider when making fungicide decisions and on farm trials on the Illinois Field Crop Disease Blog, which can be found by clicking HERE. …
