It is a little early to be discussing Fusarium head blight (FHB) , but it is something that always seems to come up in conversation. Currently our wheat has yet to to hit jointing, and it will be a while before we are at the flowering stage. …
The University of Illinois Extension will host the Ewing Demonstration Center Agronomy Field Day on Thursday, July 27, 2017 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,…
Despite the snow falling outside of my window this morning, plans continue for the upcoming survey season. Mother Nature has hinted at spring with temperatures in the 70’s just last week and its time to start thinking about spring insect trapping.
We are starting to look for cooperators that are willing to place and monitor traps for black cutworm and true armyworm this spring and European corn borer, corn earworm, fall armyworm, and western bean cutworm this summer.…

This past growing season personnel from Southern Illinois University, Iowa State University and University of Illinois evaluated more than 580 soybean varieties from 22 seed companies in USB-sponsored sudden death syndrome (SDS) variety trials. The varieties that were evaluated ranged from the very early (MG 0) to late (MG V) maturity groups. Maturity groups were divided into early and late categories; for example, MG II was split into early (2.0 to 2.4) and late (2.5 to 2.9) categories in order to more easily monitor crop development and assess disease at the appropriate growth stage (Figure).…
Soybean rust (Phakopsora pachyrhizi) has been found in southern Illinois. Samples were collected in Williamson county on 9/11/16 to make observations for other fungal foliar leaf disease. Soybean rust was found sporulating in pustules on the bottom surface of the leaves. The field was at R6 so yield loss to that field is unlikely. While this very late in the season, there are still many fields in southern Illinois that are green and producers should consider scouting for soybean rust.…
Corn leaf samples from LaSalle county have been positively identified by the University of Illinois Plant Clinic to be infected with Tar Spot Phyllachora maydis. Commercial Agriculture Extension Educator Russ Higgins found the disease while field scouting. The fungal leaf blight was identified in numerous northern Illinois and northern Indiana counties in 2015.
Tar Spot has distinctive signs and symptoms. The fungal fruiting body, called an ascomata, looks like an actual spot of tar on the leaf. …
