I'll cite myself on this one. I've worked on two organic farms, both in very different environments (CA & FL), and neither used more than a trivial (or less) amount of pesticide. Regarding your difficulty imagining using less pesticides unless a monoculture; well, it's been the opposite in my experience - it's daunting just to think of listing everything grown on the farm in FL. And contrary to the many comments here asserting the inefficiency and unreasonable cost of organic farming, I have yet to observe much to corroborate. As for the quality of product, it's excellent, well beyond mere subjectivity.
