Slightly tangential, but regarding the definition of "natural," I personally prefer to think in terms of concentrates. The chemicals in question exist in nature in many cases, or at least there is a similar naturally occurring compound. The main thing that I think makes a useful distinction is the concentration level. Like other drugs, the danger is in the dose, and the extreme levels of potency we can get with a little chemistry is what makes them "natural" or "synthetic" in my opinion (regardless of their actual origin). I'm more cautious accepting highly concentrated substances than I am accepting the same thing diluted with the thousands of other naturally occurring substances that accompany it "in the wild."

Pesticides in organic farming are also highly concentrated (see https://en.wikipedia.org/wiki/Organic_farming#Pesticides), which would make them synthetic per your definition. Which is fine, but it means that from your perspective organic farming is non-existent.

Yes, that's absolutely correct, and is actually part of the point I was attempting to make. I grow vegetables and fruits at small-farm scale (1-3 acres in production generally) in a way that I'd call organic if the term wasn't already taken - I don't spray anything at all, and use no concentrates for fertility or weed control. This has the predictable effect of reducing my overall yield in the short term, but I've found that I can still produce well as long as I'm careful to choose crops that are adapted to my region and use high biodiversity insectary plantings and trap crops for pest management. Weeding is done mechanically (usually with a hoe or a wheel hoe, occasionally with the walk-behind tractor for large areas).

I know many organic farmers who follow practices similar to mine as well. The organic name is really more of an indicator of intent for a lot of people - you can get away with a lot of things and still be certified, but most of the growers I know actually do make a strong effort to find another way. So, the organic label does actually carry some weight with me despite the fact that it can be abused.
