Dicamba News

With new dicamba and 2,4-D post-application use on soybeans coming to the marketplace, there is a lot of activity occurring.  With at least one post-application dicamba formulation now registered for use in 2017 on soybeans, several states are taking actions to ensure judicious use in light of the misuse that occurred in Missouri and Arkansas last year.  Indiana is proposing rules to require that all dicamba products be classified as Restricted Use for the sale and use of these products in Indiana.  Arkansas is also seeking RUP status, prohibiting application after April 15 for some formulations and banning older formulations completely.  RUP status means that the products can only be sold to licensed applicators, by licensed pesticide dealers, and that a record of the application must be kept. 

IFCA requested a meeting with the IL Dept of Ag, several Illinois farm groups and the UI"s Dr. Aaron Hager to discuss these developments in surrounding states, stewardship concerns and possible avenues for proactive efforts in Illinois.  As always, IFCA's mission is to be proactive on issues that impact our members and to promote the stewardship of agricultural inputs.  As Indiana and Arkansas move forward with their efforts, IFCA will keep you informed on how this impacts product use in those states.  In the meantime, IFCA has stewardship efforts in place; we have a full 1/2 day at the IFCA convention on January 19, 2017 on dicamba use and weed management.  We also have sessions on this topic during the CCA portion of the program on January 17. Weed scientists from Missouri and Arkansas will share the lessons learned in their states and advice on management.   Go to and click on "Convention" to view the program and register for the convention.  The IFCA Board and staff welcome your thoughts on this issue, so please contact Jean Payne or KJ Johnson to share your perspective as a IFCA member.
