Under a shade tree at the Northern Illinois Agronomy Research Center north of Shabbona, Carl Bradley, assistant professor in the University of Illinois Crop Sciences Department, discussed Goss' wilt. A bacterial disease that affects corn, Bradley said it can appear at any stage of growth, any time the plant is damaged, allowing the bacteria to enter the plant. He said the earlier corn is affected, the more detrimental it will be to yield. Other topics discussed at the annual agronomy day were crop rotation and corn management, weed control challenges, cover crop studies, brown marmorated stink bug in Illinois and more.
