The risk of weeds developing resistance to a herbicide site of action is determined by how the herbicide is used and the frequency of resistance mutations in weeds. The more a site of action is used, the greater the risk of resistance. LEARN MORE IN THIS NEW FACT SHEET from USB.
Many issues can occur in soybeans during the reproductive stages, such as evidence of insect feeding, stunted pods or damage or discoloration. READ THIS ARTICLE from USB for some common issues, as well as possible causes to help diagnose the problem and take steps to address it.

The NCSPA has widely published information from research studies that have shown increases in yield in N.C. conditions, such as in THIS ARTICLE from June of 2016. Many farmers are already implementing practices these or other practices that will improve yields. However, it’s always good to have a reminder of things that can be easily…
Many farmers do not realize that weeds that are not managed can also cause problems with insect pests. Insects feed on alternative host sources before going into soybeans when they start to bloom. Some insects may have three generations built up in weeds before soybeans are vulnerable. Learn more in THIS ARTICLE about what can…
Today’s sprayers can apply just the right amount of herbicide to every inch of a field, but one size does not fit all. Nozzles come in many types and spray patterns, and the best one to use depends on the plan for using it. For instance, different size nozzles work better with different types of…
Weed scientists often see farmers making the same mistakes when managing their fields. Common ones include: Applying herbicides when weeds are too tall Not using residual herbicides or not using them at adequate rates in pre-plant/pre-emergence programs Applying herbicides at rates lower than the labeled minimum Using ineffective herbicides for weeds that are in the…
There are lots of great apps these days that can help with weed management that can be uploaded to your phone to have handy to use in the field. There’s a Site of Action Lookup Tool, a Weed ID app, a Windfinder app to make it easy to identify which direction to spray and an…
Dicamba is in the headlines now, with new herbicide-tolerant traits coming to market and recent approvals for over-the-top application. And rightly so because it offers soil residual activity with over 14 days of small-seeded broadleaf weeds, control of weeds that have developed resistance to other modes of action and extended flexibility in application timing in…
If a management plan to combat herbicide resistance is not something you have yet, there are some steps that can still be implemented this year. Weed management scientists say a few steps can go a long way, such as: Starting Weed-Free: Whether by cultivation or burn down, this step is important. Think Pre: Rather than…
Have questions about synthetic auxin herbicides? USB recently created a fact sheet to address some common questions and concerns about over-the-top applications of 2,4-D and dicamba herbicides in soybeans.
