"Missouri will limit the use of a weed killer made by BASF SE after farmers complained the chemical drifted and harmed their crops, following a move by Arkansas to prohibit sprayings next year of the herbicide and rival products.

Missouri on Thursday banned sprayings of BASF’s Engenia herbicide, which is based on a chemical known as dicamba, in 10 counties that had high numbers of complaints about crop damage, starting on June 1, 2018. The ban will expand statewide on July 15 and end in October.

Missouri said it expects to impose similar bans on dicamba herbicides sold by Monsanto Co and DowDuPont Inc. "
