> I don't mind manure

I usually don't, but I once had a neighbour who found it clever to spray liquid manure through the water cannons which are normally used for watering maize... I just let you imagine for a minute the atmosphere in the whole municipality when he was doing that.

Don't know about USA, but in Europe there are very strict laws about pesticide use (things like wind speed, droplet size and buffer zones) to make general public safe. As a certified agronomist (person who give orders to start spraying) but to some extend also tractor driver you are personally liable to follow the rules. I am sure similar legislative is in use as well.

This is true, but in the nature of farming areas today. Moving there and it's what you will face.
