That side of their legal battle is very tough to fight and defend on a %. If they own and plant side by side in set crop areas you cant stop a delivery or a mass of workers because of wind.

I dont know about US practices,but we used to have super phosphate dropped on our roof by crop dusters so that went straight into our water tanks you could hear the pellets hitting the roof like bullets, they were ment to spread it out on the grass next door not near us, but wind etc. Thats the stuff we could hear, when they came across spraying chemicals thats worse, (not knowing what next door ordered in while you were at work etc).
Automation and chemicals has had its down sides, if it gets into your dna your whole line will pay.
