This incident is interesting since it enlights both
the need of an alternative treatment and the vacuum
let by official agencies in Noth America. You (and I)
are lucky enough that Swiss, German, Danish, Finnish
and Swedish (sorry for those I forgot here) made the
effort to publish some of their studies in a foreign
language otherwise what would have been the recipe ?
I had a look at the Arla (PMRA in English) web site.
Correct me if I am wrong, but in order to register a
"pest control product", one has to fullfill the
homologation application and pay afferent fees,
according to the Bill C28 (new act on pest control).
So what happens when no private corporation is
inetrested in such investment beacuse the product is
cheap and widely available (namely there is no money
to make with it) ? You need a "stakeholders"
association, federation, council or board to invest
for "the common interest", don't you ? Hypotheses are
that this entity is rich enough (or have available
money) to fill the application and is enough
representative of the "common interest" (namely not
controled by a handfull od individuals with different
inetrest that the "common interest"). Finally, I want
to point out that this structure is not adapted to
cases like Ox. Acid approval. Beekeepers are looking
for cheap easy to produce "organic" product to control
varroas but the approval procedure is based on market
forces focusing on high fast return on investments. So
we will have the same problem for each cheap easy to
produce product emerging in the future. Am I far away
afield ? Or are my thoughts somewhat correct ?
A "pest control product" is defined by a product, an
organism or a substance [...]used as a means for
directly or indirectly controlling, destroying,
attracting or repelling a pest or for mitigating or
preventing its injurious, noxious or
troublesome effects; (please see the law for complete
definition). You can use it only if it is registered
on the official register. Namely, as I understand it,
if you use sugar against varroa or vinegar against
nosema, you are clearely using a product directly
against a pest, so it is a "pest control product", so
you are outlaw if it is not registered. Ça va mal à la
shop, as they say here. The French AMM process has
quite the same drawbacks and same questions are asked
to them about the same products. I wonder how those
who obtained official approval in their countries get
out of this kind of process. Is their approval system
different ?
But in the same way, Arla-PMRA has an official policy
to support "Sustainable Pest control"
(http://www.hc-sc.gc.ca/pmra-arla/francais/spm/spm-f.html)
although I do not see, on their publication, how it is
translated in the reality (but this sector is quite
unfamiliar to me). I am wondering how this agency will
make us life easier for next products that could help
beekeepers on the "sustainable pest control" when no
private company is interested in investing in the
homologation process.
With regard to Ox. Acid use, the SBB seems and
advantage to me whem using a vaporizer.
1. It makes space under the screen to place the
vaporizer. I have plastic frames and I don not want to
place the vaporizer to close to the frames.
2. Ox. Acid tends to re-crystallize on the screen, it
is better when you can remove the screen (which is my
configuration, the screen is stapled on a frame
inserted in the bottom board)
3. Under the screen, I have a styrofoam sheet that I
can add or remove also, so that I can close or open
the space under the screen. Just add a piece of wood
under the vaporizer and on the styrofoam.
4. When vaporizing Ox. Acid, if hive is correctly
closed for 10 min, you are no in contact with Ox.
Acide vapors. You only manipulate crystals for 2
seconds (from the spoon to the vaporizer).
With regard to H&S issue for Ox. Acid, someone
mentionned, on the Belgian list, a complete article
published by a German PhD student in a Swiss
beekeeping journal. I still have not read, ich hoffe
diese publikation ist nicht auf Deutch, weil mein
Deutch sehr schlecht ist.
Read me until the end ? congratulations !
