The best tactic you can follow in the US is to try and buy imported produce from countries with stricter pesticide laws.
I don't know much about the US rules. But I also know here it's popular to say "well just because it's organic, doesn't mean it's without pesticides".
But in general the few times I've checked different researches on pesticide residue organic scores consistently better.
Up until very recently, organic included the use of rotenone, which is a 'naturally occurring' poison that causes parkinson's in mammals.
Modern synthetic pesticides are far, far from great but they're still better than their natural counterparts.
Far too much generalisation there. There are thousands of synthetic pesticides, and dozens (hundreds?) of "natural" ones (ranging from gelatine to roteome).
A broad brush comparison is useless
Needing to ban a 19th century pesticide in the 21st century is not a broad brush, but proof of the growing common misconception that naturally occurring means safer than synthetic - the entire basis of the Organic label.
"This includes herbicide, insecticide, nematicide, molluscicide, piscicide, avicide, rodenticide, bactericide, insect repellent, animal repellent, microbicide, fungicide, and lampricide."

Again, it's very dicey comparison. I'm not advocating convention > organic, but feel the need to pushback on people that think organic > conventional
This is a very grey subject and it should be debated as such.
