This past week we spent a few days surveying wheat fields throughout the state in order to see how the crop is progressing as well as better understand what disease related issues we may be experiencing. Most of the crop was near flag leaf emergence (Feekes growth stage 8/9) with a few fields near boot in locations further south. The good news is that of the 26 fields we looked at, none had any stripe rust,…
I received notice of stripe rust in S. Illinois today. Stripe rust is an important disease affecting wheat. Please find an article on this disease and management by clicking here.
If you locate stripe rust in your field please tweet a picture to me (@ILplantdoc) or email (nathank@illinois.edu) with the wheat variety, growth stage, and approximate percent of field infected. This information will be useful to IL wheat producers this year and in upcoming seasons.…

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).…
