Earlier this year a federal court determined that the U.S. EPA unlawfully approved dicamba for use over the top of emerged soybeans and cotton crops designed to withstand the herbicide. Existing products registered before the February 7 decision could be distributed through EPA’s existing stock order.

For retailers selling dicamba-based products and farmers who wish to use them, looming deadlines are rapidly approaching. May 13 was the last day to sell existing stocks in Iowa, Illinois, Indiana and Minnesota. May 21 is the last day for sale in South Dakota and the other states have a deadline of May 31 for soybeans and June 30 for cotton.

No dicamba-based product can be applied to soybeans after June 30 or cotton after July 30.
