A system that collapses if one component is removed or fails to perform is dependency not agronomy?

That was the original question.

For the fourth time. No it's not dependency. Systems (even if you don't like them) are interconnected web. You can cut so many connections that a system collapses. But that doesn't mean there still aren't some connections. That does not make for dependency.

And I answered your new question about anything you've said that was scientifically incorrect. You are scientifically incorrect that a plant can be immune from all disease because it's in a natural system. That has been my thesis since my first post. Disease existed in natural systems before agriculture was invented by humans. You cannot make a plant healthy enough to withstand all disease.
