If you aren't selling it your not in any violation. Especially if it is a different gibb then what they are using. Ain't going to kill the corn either, not with the amount that was used.

We tried Valent's wheat seed treatment PGR that has 4% gibb in it. Had great success with planting and emergence. We have it planted next to Ascend. Time will tell to see if any of the wheat makes it through the icy winter.
