Due to May flooding from heavy spring rains, replanting of corn and soybean continues in eastern and southern Nebraska. Here are two factors to consider regarding herbicide use in replanting.

One of the challenges with spring burndown application is timing. Wet and windy conditions can delay spraying and under these conditions weeds can grow significantly in a few days. Waiting until planting to spray troublesome weeds such as marestail may be too late to achieve adequate control. In addition, waiting until soybean planting limits the available herbicide options since there are relatively few labeled effective burndown chemicals for spraying at this time. The following section identifies key treatment aspects to consider for several resistant varieties in Nebraska.
