Dicamba is no longer an option for some soybean farmers

The EPA deadline for over-the-top dicamba applications for soybeans in four states has come and gone.

Purdue Extension weed scientist Bill Johnson says June 12th was the last day for application in Illinois, Indiana, Iowa, and southern Minnesota, but…

“We still have the ability to use other herbicides and in particular to glyphosate or liberty type of products will will get used pretty extensively, but it does take a pretty important tool for control broadleaf weeds out of our toolbox,” he says.

He tells Brownfield applications in those states are not permitted moving forward. 

“Any applications past that date will be subject to whatever fines and punishments are typical of off label herbicide application,” he says.

Johnson says he anticipates more restrictions on dicamba use coming in 2025.

“As you go through seed purchasing decisions later this summer and into this fall, make sure you have a full awareness of of where and when you can use dicamba and extend flex soybeans next year,” he says.

The states with a June 12th cutoff deadline include three of the five top soybean producing states in the country.
