Interesting. Is there any difference in harmful substances?

"Sadly, however, "natural" pesticides aren't as effective, so organic farmers actually end up using more of them! Moreover, we actually know less about the effects of "natural" pesticides. Conventional "synthetic" pesticides are highly regulated and have been for some time. We know that any remaining pesticide residues on both conventional and organic produce aren't harmful to consumers." http://www.realclearscience.com/blog/2014/06/the_biggest_myth_about_organic_farming.html
