Many of the "organic approved" substances are also incredibly dangerous. Rotenone is a naturally derived neuro-toxin linked to Parkinson's. Pyrethrin is poison. Then you have a bunch of chlorine and ammonia based elements - maybe not as dangerous in their pure industrial concentrations as paraquat would be but certainly not safe.
(Paraquat is also very unique because it neutralizes itself in contact with soil so it's actually a lot safer in a lot of situations).
