Sure, but that doesn't change the fact that his crop is being pollinated against his will, and why should he lose the freedom to spray something on his crop because his neighbor planted a certain seed? Why does it have to infect everyone like a virus?

Because spraying roundup on non-roundup ready crops has 1 outcome, it kills them. There is no reasonable reason to do it other than to avoid the patent.

If roundup ready crops end up in your fields accidentally and then you don’t spray roundup you don’t run afoul of litigation.

Spray his crops with something that will 100% kill all of his original crop and only keeping the cross contaminated crop, which he will then specifically cultivate. Common now, it's really a shut and close case. He had no explanation as to an alternative valid reason to have done so and lost the case.
