Minnesota is maintaining its June 20 cutoff date for farmers to use the herbicide dicamba, which has been blamed for drifting and damaging neighboring soybean fields.

The Minnesota Department of Agriculture imposed the cutoff for 2018 after getting 253 reports of alleged dicamba drift in 2017, including 55 formal complaints requesting investigations. Some 265,000 acres were affected.

Agriculture Commissioner Dave Frederickson said Monday that the restrictions worked well.
