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.…
MONMOUTH, Ill. – The Northwestern Illinois Agricultural Research and Demonstration Center near Monmouth has scheduled a field day for July 18. University of Illinois crop sciences faculty, researchers, students, and Extension specialists will address issues pertinent to the 2018 growing season.
The program will begin promptly at 8 a.m. on Wednesday, July 18, and is open to the public at no cost.
Weather permitting, presentations will take place outside next to research plots. Participants will board buses to tour portions of the farm.…

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. …

Every year we hear about fungicides, and their utility in agronomic production systems. Indeed, these products can be an extremely useful tool to prevent yield-related losses resulting from fungal diseases. However, reduced commodity prices are making it crucial for producers to minimize inputs in order to maximize profits. …
