Agronomist touts effectiveness of early season dicamba

With earlier deadlines for dicamba application, an Illinois-based agronomist recommends farmers put together an extensive weed management plan.

Kurt Maertens with BASF tells Brownfield farmers should start with dicamba.

“I want it used in the burn down or the early post-application and that is where it is going to work well because things might be a ,little bit cooler. We need a systemic herbicide. That will always look better in that application setting.”

He says utilizing multiple modes of action is critical to controlling problem weeds like waterhemp and palmer amaranth.

“Then the nice part is, if we are using XtendFlex soybeans we can come back with Liberty, yet a different effective site of action. So, we are really giving those weeds a one-two punch as well as layering those residuals.”

Maertens says dicamba is an important tool for corn and soybeans farmers, but the key is learning the best time to use it.

The EPA recently announced federal dicamba label changes that prevent application on soybeans after June 12th or the V4 stage in Illinois, Indiana and Iowa for the 2023 season.
