Nebraska Extension educators and specialists would like to hear from growers and agribusiness about their experiences with dicamba this season. Information can be shared via an online survey or by contacting them directly with the email provided.
Reports of suspected dicamba injury to soybean and other sensitive crops are increasing. The author reviews application windows for dicamba in corn, a possible area of concern, and outlines what growers can do if they suspect dicamba injury in their fields.
Liberty has revised its label to provide for an increased application rate in corn and soybean. View the new label rates for corn and soybean with a cumulative maximum per year of 87 fl oz/acre for either crop.
Dicamba-resistant soybean, genetically engineered to provide resistance to dicamba and glyphosate, was made commercially available for the 2017 growing season. This article looks at potential dicamba injury to sensitive crops and plants.
This week growers facing challenges with Palmer amaranth questioned whether it was due to the product, the environment and lack of rain, or a resistant weed. Several factors could be at play, notes a UNL weed scientist, who recommends starting with preemergence herbicides with residual activity to get the best control.
It's important to consider soybean growth stage and preharvest interval when applying postemergence herbicides to avoid potential crop injury. This article describes how to determine crop growth stage and includes a table of application restrictions for common postemergence herbicides.
When applying postemergence herbicides, consider corn growth stage, weed species present, and crop and weed heights. The article includes how to determine corn growth stage, recommendations to avoid problems, and a table of application restrictions for common postemergence herbicides.
Controlling glyphosate-resistant volunteer corn is a major challenge in some soybean fields this year as preemergence herbicides aren't very effective. Postemergence herbicides will be critical to its management.
