Dicamba – it’s a hot topic these days, and an important one to pay attention to. The EPA has classified three formulations of dicamba as Restricted Use Pesticides for 2018 - BASF’s Engenia®, DuPont’s FeXapanTM, and Monsanto’s XtendiMax®. Dicamba is a Group 4 herbicide, one of only a few herbicides in this site of action that is available for post-emergence use in soybeans. It’s an important tool to have in the toolbox, and requires careful stewardship to ensure farmers continue to have access to the technology. With this classification comes the responsibility of following the regulations associated with these products in order to keep these formulations in the lineup. As the growing season and application window quickly approach, here is what you need to know about handling these dicamba formulations before you get out in the field.
Anyone applying Engenia, FeXapan or XtendiMax at any point in the 2018 growing season must attend a dicamba or auxin-specific training and be able to present proof of attendance. Federal law states that training can be completed through university or industry sources. Training sessions are offered by BASF, DuPont, Monsanto, extension and other local groups. However, it’s important to note that applicators in Alabama, Georgia, Indiana, Missouri, Mississippi, North Carolina and Tennessee must attend training conducted by the state. See the links below to locate a training near you.

Regardless of whether you are using Engenia, FeXapan, or XtendiMax, it is extremely important that you read the label thoroughly and make sure you understand exactly what is required when using that product. Read it now, read it later, read it before you apply – know what you’re dealing with and how to handle the situation.
Some of the updates to the national labels for 2018 include:

It’s also important to keep in mind that regulations vary by state, so check with your local pesticide regulatory authority to see what is the standard for application in your state. In situations where state regulations are more restrictive than federal regulations, state laws trump federal laws.
