Scouting shouldn't end until after harvest

Scouting is a season-long commitment, beginning before planting (measuring soil temperature and assessing condition), continues after planting (assessing plant stands and then scouting for disease, insect and weed pressure) only ending after the crop has been harvested. Late season scouting of corn can include monitoring kernels for maturity (black layer) and moisture content and checki...

Making informed foliar fungicide decisions = scout before tasseling time

Foliar fungicides in corn - a historical perspective. From the early 1970's through the mid-2000's, when prices averaged close to $2 per bushel and corn was considered a lower value crop, producers worked to minimize all but the most essential inputs. Between 2010 and 2012, when corn prices reached historic highs, producers may have considered additional inputs. While many prod...

Keep an eye out for bacterial leaf streak in corn

Posted by Angie Peltier - Disease

Last growing season (2016) a new corn disease called bacterial leaf streak (BLS) was confirmed in Illinois for the first time in DeKalb County. Symptoms of BLS include narrow yellow, tan, brown or orange lesions with wavy margins that occur between and along leaf veins (Figure). While symptoms of this disease were observed in Nebraska as early as 2014, it took scientists several years t...

Following Crop Development in a Corn Planting Date Trial

You might have always wondered whether there was some way to estimate when your corn crop is likely to reach the silking and black layer growth stages. Well you might just be in luck if you gather the following information about a particular corn hybrid (when it was planted, where it was planted, its estimated days to maturity) and use any internet browser to visit...
