Arkansas State Plant Board Changes Regulations for New Technology

Arkansas State Plant Board regulation changes for Dicamba (Monsanto Enlist and Xtend technology) and 2,4,D choline (Dow Enlist Duo technology) were made at a recent Plant Board meeting. The new regulations prohibit the application of dimethylamine salt and acid formulations of dicamba except pastures that are 1 mile in all directions from susceptible crops. From April 15 through September 15 of each year, products labeled for agricultural use that contain diglycolamine salt and sodium salt of dicamba may not be applied. For the first year of registration and the following year BASF’s product identified as Eugenia Herbicide may be used on Roundup Ready Xtend cotton and soybeans with the following conditions. During applications of Eugenia, a 100 ft. buffer zone in every direction except ¼ mile downwind from the field of application to susceptible crops must be maintained. Wind speed during the application may not exceed 10 MPH. These are primary restrictions; however, the regulations have tank mix restrictions and if label is more restrictive than regulations then label must be complied with. In addition, applications made with the classifications in the ASPB regulations by commercial, non-commercial and private applicators must first complete new technology certification training. The training will be offered by the University of Arkansas Cooperative Extension Service.

Arkansas Governor Approves Plant Board’s Limits On Dicamba Use

     Gov. Asa Hutchinson has approved proposed regulations by the Arkansas Plant Board to limit use of herbicides containing dicamba.  Hutchinson said Wednesday that he’s determined the proposal will not cause unnecessary burdens on businesses but said the methods and research used by the board must be clearly defined and he wants the board to provide “clear rules” within 45 days.  Dicamba is a relatively inexpensive weed killer but is prone to drift and damage nearby row crops such as soybeans and cotton in addition to fruit and vegetable farms and ornamental trees. The proposals include banning dicamba known as DMA except on pastures at least 1 mile from susceptible crops and prohibiting dicamba known as DGS from April 15-Sept. 15, except on pasture and rangeland with a 1-mile buffer zone.
