Interpretive Summary: Claims have been made that glyphosate application to glyphosate-resistant (GR) crops can result in deficiencies in certain mineral elements in those crops and that this is a cause of increased plant diseases. Strong evidence from multiyear and multisite studies has not verified these claims. Furthermore, these studies and others have found that glyphosate has no effect or a slight stimulation on yield of GR crops.
