If the contracting party, after being so advised, continues to require the commercial applicator to perform the application or use the device according to these instructions, the commercial applicator may follow these instructions for the application or use unless the application or use would violate any of the directions contained on the pesticide or the device or the labeling of either or would violate any provision of this article 10 or article 9 of this title 35 or any rule adopted pursuant to this article 10 or article 9 of this title 35.
