When severe storms and hail hit your corn and soybean fields, it's important to estimate yield losses to determine the need for future inputs and alternative management strategies. This guide offers steps to evaluate mid-season hail damage and estimate potential yield losses.
After recent severe storms that rolled across parts of Nebraska, growers are encouraged to wait 7-10 days to fully assess crop damage and determine next management steps. Research-based estimated yields from replanting now are included.
In 2017 large populations of painted lady butterflies were seen across the state, raising concerns about whether the larvae form (thistle caterpillars) of this insect would cause damage to soybean fields.
As corn begins to emerge, be alert to the potential for damage from early season insects such as cutworms, wireworms, white grubs or wheat stem maggot. Seed treatments provide some protection, but can be overwhelmed in some circumstances, allowing losses.
From the 2018 Crop Production Clinic Proceedings: Corn rootworm continues to be a problem for Nebraska growers who rotate crops infrequently. Additionally, resistance to insecticides and some Bt corn reduces efficacy of these important tools in some fields.
Should the cold spring delay cover crop termination? Growers walk a fine line between growing cover crops long enough to get the biomass they want without reducing yield in the following grain crop. This discussion from an agronomist, entomologist and weed scientist looks at various factors to consider.
