A brush with low doses of the herbicide dicamba spurs oxalis, a weed commonly known as wood sorrel, to produce more flowers, University of Michigan researchers have discovered. The finding suggests that farmers and homeowners are inadvertently making weeds growing around the perimeter of their fields or lawns stronger, the researchers say. The study results are published in the journal New Phytologist.
