Excerpt from The Rusts of Cereal Crops

Much has been published concerning the rusts, but it was not until near the middle of the eighteenth century that it was dis covered that they were fungi. Prior to that time there were vari ous popular beliefs as to the cause of rust, chief among which was one held by the Romans, which attributed the periodic ravages of the scourge to a special rust god, Robigus, who resorted to this means of wreaking his vengeance on a wicked people. Another and more persistent belief one that prevails here and there even to this day, attributes rust solely to the weather. We now know that weather greatly affects the development and spread of rust; we know also that there can be no rust without the causative fungus, a parasitic plant that finds its way into the tissues of a plant and draws its sustenance from them, thereby materially injuring the plant.
