Conventional IPM programs use more toxic, but muuuch less volume of pesticides.

Organic programs user "better" pesticides, but much much more.

Which is better? We'll, it depends on how fast those pesticides break down and what those degraded molecules are. It depends on how much volume is applied to the produce. It depends on if it accumulates in the flesh of the produce.

What if a pesticide outrageously lethal to humans, but breaks down in 2 days and you only apply it in the first 25% of the produce growing window?

Which is worse? 400 lbs of feathers accumulating on your chest at 100 lbs/week for 4 weeks or 400 lbs of steel on your chest applied once.

Silly metaphor, but the answer to incredibly difficult system problems is really "it depends". Conventional vs organic is not clear cut.

Certainly agreed. Note that the guidelines I linked above do permit certain synthetic pesticides, despite their somewhat confusing use of the word "conventional" in the text that I quoted. For example, cyflumetofen is synthetic, and it's in their lowest-risk category. Copper hydroxide products are permitted under OMRI organic guidelines, but forbidden or restricted here.

I generally like the idea of more restrictive voluntary guidelines based only on safety to the ecosystem and consumer, and not on naturalness like for "organic". I haven't seen much commercial uptake, though.
