Sean, I believe you are talking about the statement that is generally covered under "Environmental Statement" or hazards.
What I am referring to is under the "General Use" category. In the National Pesticide Application Certification Core Manual, pg 43, they explain that "It is illegal and considered a misuse to use any registered pesticide in a manner inconsistent with its labeling. Examples of pesticide misuse include applying a pesticide to a site that is not listed on the label..."
On pg 21, they list specific exemptions granted under Section 2(ee) of FIFRA. "Section 2 (ee) contains provisions that exclude several application procedures from being classified as uses "inconcsistent with product labeling." (They also note that specific agencies may not allow these excemptions and to check with your state regulatory agency.) But none of the exemptions list being able to spray a site NOT listed on the label. You can apply pesticide for a target "pest not specified on the label if the pesticide is applied to a crop, animal, or site specifically listed on the label." But not the other way around.
While studying for the pesticide applicator's license, which I hold on a noncommercial research and demo basis, I was struck by the fact that if everyone actually followed all the rules and regulations, that a FRACTION of the pesticides would be applied to our environment. Unfortunately, I personally believe most people become inured to the dangers and hazards, shrug their shoulders and spray or apply away.
