    Over the last two weeks, we have received several samples of corn ears with symptoms typical of Diplodia ear rot. This is one of the most common ear diseases of corn in Ohio. It is caused by two species of fungi, Stenocarpella maydis and Stenocarpella macropora. The most characteristic symptom and the easiest way to tell Diplodia ear rot apart from other ear diseases such as Gibberella and Fusarium ear rots is the presence of white mycelium of the fungus growing over and between kernels, usually starting from the base of the ear.

    Harvest has started in some areas of Ohio. At the Farm Science Review we have some of the crop off to allow demonstrations to begin. Field demonstrations will include soybean and corn harvest, of course; plus drones/UAVs, soil sampling, planters, precision nutrient placement and drainage installation.

    Growers may be interested in wide-row wheat production due to reductions in equipment inventory (lack of grain drill) and to allow intercropping of soybean into wheat. With funding from the Ohio Small Grains Marketing Program and the Michigan Wheat Program, we’ve conducted several wide-row wheat trials.
