    Default Is wood bleach the wrong stuff?

    https://www.walmart.com/ip/Savogran-...&wl13=&veh=sem

    Is there something to buying "pure" oxalic acid from a bee supply place vs just picking up wood bleach from a hardware store? I've heard "oh wood bleach that's the wrong stuff" but its usually followed by "it may have other stuff in it."

    From what I gather there are 3 reasons, correct me if I'm wrong
    Wood beach usage not legal
    Possible toxic by-products
    Dosage is affected by purity of Oxalic

    I'll probably get oxalic from the nearby dadant store in the future but I was curious if anyone had heard of anything negative in the wood bleach

    The Savogran brand of wood bleach is close enough to 'pure' oxalic acid for beekeeping purposes. http://www.savogran.com/patch-and-repair.html

    Note that Federal pesticide regulations require that any product used as a pesticide be labeled for such use. That means that "wood bleach" is not compliant for use as a pesticide as it is not labeled as such.

    AFAIK Brushy Mountain Oxalic Acid is the only oxalic acid product available in the USA market that is properly labeled to control varroa. That Brushy Mtn OA labeled product is also sold at Dadant, and and perhaps other outlets as well.

    Savogran is 99.7% pure OA. BM is 97% pure.

    The only OA approved by the EPA is the one Brushy Mountain holds the license for.. The OA. you use must have this label for beekeeping. OA must be approved for your state also. And is distributed by several major beekeeping supply houses..

    You may like to read the directions on how you're supposed to use Oxailc acid .
    Something to remember the label is the law. I Hope you have a great day.

    You will find it on page 3 and 4.

    You are 100% right on the active ingredient. Where the problem comes in you do not know what the Inert ingredients are. In either one of the products you mentioned.

    If you use Savogran or the stuff Brushy Mountain has and one is labeled for bees and the other isnt do you really thing an EPA agent is going to visit you while you are vaporizing your hives and checking to see your label on your OA? I think not!!!!

    I have not heard anything negative other than the legality of it not having a miticide usage label. I've been using it here this year in a varroa dribble solution for treatments and have not noticed any ill effects from it so far.

    I always follow the label; If the sign says 60 MPH, I would never go plus ten. And I never would stretch the truth.

    If the product is 99.7% pure, do you really care about the .3% inert ingredient?

    ebay has some that is cheaper - free shipping- and comes in 1# bottles that are easier to open and close than those tubs from True Value.

    I wonder what the 3% Inert Ingredient in EPA approved formula that Brushy Mountain has ?
    Is it possible there is other some kind of stabilizing chemical ?

    The Savogram ( wood bleach ) is all you need!

    Must be a bunch of lawyers here too? Just think what would happen if a honeybee colony had a few.

    Heh heh. True but some of us can claim that we're old, going blind, and can't see that the packaging is not properly labeled.
    Allegedly someone saved the empty brown bottle from the fumagilin-b and re-filled it with OA (Savogram) but I am not at my leisure to say exactly who.
    Internet credibility is an oxymoron

    Just to clarify and ensure correct information, the epa label states 97% OA but that does not mean that product is 97%. It is 99.6% OA and Savogran (according their MSDS) is anywhere from 95-100%.
