摘要

Record-setting rains that swamped fields and delayed planting across the Midwest this spring may also harm the ability of pesticideregulators to see whether new rules covering the use of dicamba are effective.Dicamba is a herbicide that controls broadleaf weeds.

That’s what happened in 2017 and 2018, resulting inmillions of acres of damage to off-target crops in several states.
