What is it about?

Low rates of dicamba, dicamba plus glyphosate, 2,4-D, and 2,4-D plus glyphosate were applied to 18 plant species: apple, crabapple, dogwood, American elderberry, American elm, grapevine, hydrangea, red maple, pin oak, peach, pecan, eastern redbud, rose, red raspberry, strawberry, sweetgum, nannyberry viburnum, and black walnut. The plants were evaluated for injury at multiple time points after the applications to assess how these plants might respond to herbicide drift.
