Simulated dew increases volatility of dicamba from soybean leaves

Abstract Adoption of dicamba tolerant soybeans [Glycine max (L.) Merr.] accompanied by postemergence applications of dicamba resulted in off‐target movement and damage to nearby crops. The underlying cause, in some cases, has been attributed to weather‐related phenomena such as temperature inversion...

The underlying cause, in some cases, has been attributed to weather‐related phenomena such as temperature inversions, which are often accompanied by the formation of dew.
