Roundup contains glyphosate and other chemicals (mainly soap). Commercial farmers do not buy Roundup, but instead one of several generic brands containing glyphosate alone. Straight glyphosate out of the canister is no better than drinking seaweed extract (toxic). Decomposed glyphosphate (chemical 1/2 life = 2 hours) is non-toxic to humans. However, excessive use leads to excess phosphates that
are a significant problem in water ways and bad news for the amphibians you mentioned. A once-per-season spraying of farmland by aircraft 7 days prior to planting row crops creates zero runoff. Overuse by consumers is a serious problem.
