Simulated dew increases volatility of dicamba from soybean leaves

Adoption of dicamba tolerant soybeans [Glycine max (L.) Merr.] accompanied by postemergence applications resulted in off-target movement and damage to nearby crops. The underlying cause, some cases, has been attributed weather-related phenomena such as temperature inversions, which are often the formation dew. objective this controlled study was determine if simulated dew on soybean leaves treated with led increased short-term volatility. Over a 48-h period after application dicamba, volatility concentrations quantified air samples 20% when were exposed for 3 h compared that not Concentrations volatilized elevated first (0–24 h) second (24–48 24-h initiating collection samples. Dew may alter stability ultimately contributing movement.
