I cannot copy and paste from teh document so I am retyping the quote here.
Executive Summary (meaning a summurization of the entire document, its findings and it's conclusions)
This report evaluates Oxalic Acid, A Pesticide Inert Ingredient. (note, this declares OA to be an inert ingredient. not that it is limited to or that it's use as an inert ingredient is subject to this exemption. It is exempt because it is considered an inert ingredient even if it is used in it's raw form)
for which an exemption from the requirement of tolerances exists for it's residues when used in Pesticide formulations.
If you read the entire document you find they exempt it because it's residues cause no harm. Still they put a limit on the volume or quantity of OA that is exempt. over that limit and it again may be subject to regulations.
You could also argue that it is only exempt if used as a pesticide for crops. that is not what it is saying the document mentions many uses for OA including uses in medicine. Nowhere does it make an exception to this exemption for any of it's recognized uses.
Basically if you went to the EPA and said. Hey that guy is using OA on his bees. they would say we don't care.
Now I realize many think otherwise. What they do not seem to understand is I don't care what they think. Post documents supporting your argument. Show me on instance where anyone was even investigated for using OA on bees much less prosecuted for it. Show me one document that states it is illegal to use at all. Opinion is worthless misinformation and unreliable. I am certain the crystal balls of all those making their most rational guess is cracked. In other words I don't think for a moment all of you combined have enough intelligence to make an accurate guess at it. you want it to be illegal so you declare it illegal. and all you can offer to support that claim is what you think makes since.
Oh no they regulate pesticides. so anything that is used to kill bugs must be a pesticide.
Okay lets start a campaign to educate everyone on the legal ramifications of dusting bees with sugar. care to take up that argument? if it is in fact illegal to use OA to kill mites then it is just as illegal to use sugar. The only difference is that you think OA is more dangerous for whatever reasons you think that. Others say that sugar kills far more people than OA ever has or ever will. I think both sides are full of it.
