Japanese beetles are emerging in eastern Nebraska and will continue to emerge for the next couple of weeks. As numbers will be highest in field margins, growers are advised to scout across the whole field before determining the need for treatment.
By using a degree-day model, growers can account for the effect of temperature on insect development and approximate when certain insect stages will occur. See predicted cutworm flights and recommended scouting periods for 14 Nebraska locations.
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.
