In case you haven’t heard, the Environmental Protection Agency (EPA) has announced the re-registration of many in-season dicamba products. This announcement includes crucial label updates that will affect the management of some Roundup Ready 2 Xtend and XtendFlex soybean systems for 2021. Here’s what you need to know as you make your management decisions for the upcoming spring season.
Which label changes for in-season application do I need to be aware of?
- The national cut-off date for over-the-top application on soybeans is June 30, 2021.
- Increased buffer zone requirements for downwind buffers of 240 feet in counties without an endangered species, and a downwind buffer of 310 feet and 57 feet omnidirectional in-field in areas with endangered species.
- Over-the-top dicamba products need to be tank-mixed with an EPA-approved pH-buffering agent prior to application; EPA will enforce the use of the pH-buffering agent by keeping accurate records.
- Labels for over-the-top dicamba products will only include uses for dicamba-tolerant soybeans, and cannot be applied to non-dicamba tolerant crops
How will this affect my farm?
If you are going to plant Xtend or XtendFlex soybean varieties, you can use the labeled dicamba products as long as you follow the new federal label requirements. However, the state of Iowa may enforce additional restrictions. Work with your TRC agronomist to make sure you are complying with state and federal requirements for these in-season applications.
How can I reach the optimal ROI for my soybean acres?
- Take a systems approach to management
- Don’t just focus on the trait package, but rather the overall yield potential of your seed
- Match the right herbicides, adjuvants, and plant nutrition products
- Choose and order products early to get the best prices
- Make the most of your investment by following proper spray management practices
- Follow through with in-season management
- Use appropriate nozzles, rates, and water volumes for herbicides
- Include the correct drift reduction adjuvants to your tank mix
- Take advantage of resources to help you succeed
- Rely on in-season data and expert knowledge to help you manage your soybean acres
