Vapor Effect Reduction from Volatile Herbicides

IntroductionDicamba and 2,4-D are growth-regulator herbicides that provide excellent broad-leaf weed control. Recently released trait genes allow for wide scale use of these herbicides over broad-leaf crops. Unfortunately, both dicamba and 2,4-D are known to have a high vapor pressure, which, under the wrong conditions, may lead to a cloud of herbicide...
