Farmers Sought for On-Farm Research Trials April 6, 2018

The Nebraska On-Farm Research Network is seeking growers to conduct research trials. At this time they are particularly seeking on-farm researchers for a study of Commence seed treatment and one comparing yields from various CRM hybrids. Other studies are available or new ones can be customized to fit a grower's needs.

Considerations for Managing Herbicide-Resistant Weeds in Soybeans: Spring Burndown April 28, 2017

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.
