Study shows environmental link to herbicide-resistant horseweed

A study by Michigan State University found that horseweed's growth type is influenced by environmental cues, with rosette plants emerging in response to temperature and photoperiod variations. Upright plants, resistant to glyphosate, are three- to four-fold less sensitive than their rosette siblings, making them harder to control.
