What Qvox and Siwolke said; do not mess around with this stuff. There was quite a discussion on Bee-l a while back on this subject. It was mentioned jokingly that someone will probably be stupid enough to try it.
It's been several months since I read the study, but if memory serves, they only tested it on simulated swarms. Not in a working hive. I seem to recall someone saying it harmed brood production. When it first come out I entertained the idea of running an experiment, but after reading the published work decided against it. There are just too many unknowns right now. OAV is effective, safe, and proven method for controlling varroa destructor.Call me irresponsible, but I had a PHD chemist do the math so I could start my own trial. A large beekeeper I work with has set aside a number of hives to test LiCl. Results are forthcoming, but here's the math:
mM, in the Nature article is millimolar, the moles of a solute in a liter of solution. LiCl is 42.394 grams/mole. At 3.785 liters per gallon, you need 4.01 grams of LiCl in a gallon of syrup to achieve the 25 Mm solution used in the Nature article. This was the MAXIMUM amount of LiCl in solution tested by the scientists. According to the article, both 2Mm (.32g/gal) and 10Mm (1.6g/Gal) solutions proved effective, but over a longer time frame.
While LiCl has the aforementioned toxic effects after ingestion (in tests, 4 doses of 2g each caused toxic effects) it is also reported to be not absorbed through the skin.
The water soluble nature of LiCl is promising, since it won't store in wax, but as it is a systemic method of treatment fed in syrup, it is very inadvisable to feed it to bees that are making honey for human consumption. I prefer to always keep any chemical or medication out of my hives when honey supers are on, but this is perhaps even more important since bees could store the LiCl solution directly as honey.
Lab grade LiCl is readily available online but carries the disclaimer that it is not for food, drug or household use. Use it at your own risk.
Is Dick just that, or is there a true legal issue here? Has anyone heard of a US lab testing this? I realize that any non-approved treatment is risky, but anecdotal evidence suggests that thousands of gallons of 12% Amitraz are crossing the border into the US and are then used in commercial beehives nationwide in a wholly illegal manner. Organic acids are dangerous to the person applying them as well, and are also deadly to larval bees. The fact of the matter is that we do not have a satisfactorily affordable mite treatment method and the faster we can get answers to the question of whether this treatment is worth pursuing or should go the way of Coumaphos, Fluvalinate and Fumagilin the better our industry will be.Richard Cryberg said:I personally hope EPA puts you in jail for ten years for breaking all kinds of laws. You are a criminal if you do the tests you propose and as a criminal should be punished enough to prevent you from doing further harm and creating risk for society. I suggest if you do this unlawful test at minimum you should kill the bees and burn all honey and hive equipment at the conclusion of the test.
To do this legally you need to get an Experimental Use Permit from the Federal EPA. At minimum that EUP will require you to burn or landfill 100% of any honey stores in the hive at the end of the test. If it is burning you would be required to burn at an incinerator licensed for waste disposal.
Dick, also a PhD chemist who has a brain unlike the moron you consulted with.
You can not legally "roll your own" pesticides. To be legal, every pesticide applied must come out of a container that has an EPA registration number, AND the full manufacturers instructions on the label [which must include dosages for the target pest].... is there a true legal issue here?
When it comes to Dr. Cryberg, I think that is an understatement. However, I find that highly intelligent people tend to be brusque in their speech. That is to say they do not suffer fools gladly. I tend to ignore the manner and focus on the content.Many people do not have a bedside manner but get frustrated with amateurs messing around with chemicals like the above.
Look under precautions on the wiki link.Potassium chloride is use now instead of lithium chloride.Could have missed it but salt substitute is/was potassium chloride don't remember lithium used that way.
