Home » Using Dicamba on Dicamba-Tolerant Soybeans
Label restrictions have been updated for three dicamba products that are registered until December 20, 2025. The products are:
- Engenia Herbicide®, made by BASF
- Xtendimax®, made by Bayer CropScience
- Tavium® Plus, made by Syngenta
These herbicides are intended for post-emergent use on soybeans that have been genetically modified to resist damage from the chemical. The registration for these products is set to expire in 2025, barring changes from the EPA. Because of numerous drift problems, crop damage and complaints, the EPA has implemented extensive requirements to try and lessen the problems, while still allowing their use.
Following are just SOME of the requirements you need to know about, and use, before applying these products. Please read the label thoroughly for all regulations. Remember, the label is the law.
All the products above are registered as Restricted-Use Pesticides (RUPs). This means you must be a Certified Pesticide Applicator to both buy AND apply (this includes mixing and loading) these products.
To use the three dicamba products listed above an applicator must be certified and go through an additional product training. This additional training is dictated by the pesticide labels. And we all know from our training that “the label is the law.” Wisconsin will accept training provided by the three companies that make the products, or approved training provided by other states. You need to have a proof that you got training to apply these products. You can find the three manufacturer training by using the following links.
Bulletins Live and Buffer Zones
The EPA has a bulletin system to help protect endangered species from exposure to certain pesticides. Some pesticide labels will direct you to the EPA’s Bulletins Live Two (BLT) website to find specific use restrictions (based on county) for the product to protect endangered and threatened species. All three of the over-the-top dicamba products will direct you to check the BLT website. In certain counties the bulletin will require you to have both a 310-foot in-field wind-directional spray drift buffer and a 57-foot infield buffer on other field edges.
