According to an article by Dan Nosowitz in Modern Farmer, Bayer that acquired Monsanto and its broad portfolio of liabilities is facing extensive litigation over drift of dicamba herbicide that has affected soybean crops in the southeast and mid-west. A new problem has arisen involving extensive damage to vineyards in Texas, Ohio and Pennsylvania.
Wine-grape cultivation has expanded in Texas and recently and farmers have suffered extensive damage as a result of dicamba drift from the herbicide applied to cotton fields in relatively close proximity. A total of 57 grape growers in Texas have 
filed suit against Bayer-Monsanto and BASF alleging up to 90 percent reduction in yield and in some cases total loss of vines requiring replanting and years to achieve maturity.
As a result of lawsuits and evident liability, Corteva Agriscience, a spinoff from Dow–DuPont that previously marketed dicamba has exited the market.
