Missouri limits use of weedkiller linked to crop damage

Missouri will limit the use of a weedkiller made by BASF SE after farmers complained the chemical drifted and harmed their crops, following a move by Arkansas to prohibit spray applications 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.

The United States has faced a weedkiller crisis this year caused by new formulations of dicamba-based herbicides, which farmers and weed experts say harmed crops this summer because they evaporate and drift away from where they are applied.

Nationwide, 3.6 million acres of soybeans suffered harm associated with dicamba, and states launched 2,708 investigations into dicamba-related crop damage, according to data compiled by the University of Missouri.

BASF and DuPont, which makes the herbicide FeXapan, declined to discuss details of Missouri’s restrictions.
