boneset

The scientists found that application of dicamba inhibited or delayed flowering in common boneset (Eupatorium perfoliatum), resulting in significantly reduced visitation by insect species, including honeybees (pollinators) and syrphid flies (natural enemies). The image shows a damaged E. perfoliatum plant that received a rate of 56 grams of dicamba per hectare.
