I also bet there isn't a farmer at that farmer's market that doesn't use some sort of pesticide, regardless of any posted "organically grown" signs.
It's really silly and naive to believe otherwise.
At market, the term "organic" means: "This stuff is undersized and damaged by bugs, but if you're dumb enough I'll let you have it for double the normal price."
Amazingly, they find customers.
There is a true saying, "No one ever went broke underestimating the intelligence of the public."
