Oxalic, when and how?

Then they should do some research, not just guess, or think something does not work.

There is research..http://scialert.net/qredirect.php?doi=pjbs.2005.1142.1145&linkid=pdf.

Quite a lot of links on the forum to other research papers as well.

Can we now get onto another topic ? <span style="font-size: 1.4em;">How about the role of the protein "Royalactin" </span>

I read that a while ago.

I also read this some place on here......And don't forget that a National deep frame can hold 2-2.5kg of honey, even when already full of brood

Here is another brief one.

My bees always seem to have brood in October. I haven't tried the formic yet but I do use the thymolated syrup. The only problem with trickling is the timing probably due to climate change.

What climate change ?

The one year I trickled oxallic acid over my bees... as I was not sure if they had been treated by previous beekeeper.... 3 out of 3 were deadouts!

I NOW ONLY VAPORISE IF I THINK THE COLONY MAY NEED IT........

My advice ... correct or not , for the novice would be to seek better advice before treating, especially opening hives up to pour on acid in midwinter!



This is my annual pre Christmas rant about bad beekeeping practices... now lets all go and stick matchsticks under the crown boards to get some good cold draught blowing through the colonies... or is it hives?


AAAAAAAAAAAAAAAARRRRRRRRRRRRRRRRRRRRRHHHHHHHHHHHHHHHHHHHHH!!!!!!

Such an over dramatic scare mongering post. 'Pour acid'...we're not talking sulphuric acid here. Better to treat if you are unsure about your mite level than to just leave it, especially when it is a harmless treatment when done properly. How many can honestly say they have no mites? If I had 10 mites I would still treat. Mites breed rapidly and it could be a long time until the next treatment. Nothing to lose by treating. Possibly everything to lose if not. Were you under scientific conditions studying every variable when you had these deadouts? If not you cannot blame the oxalic and are banding about poor advice.

Funnily enough, to lighten it up a bit, my syrup tasted just like discharged (!) battery acid.

You drank your syrup? And you've tasted battery acid in the past to make an accurate comparison? Madness

Errrm avatar picture ahem Tip-of tongue touch stuff. But OA is really not very poisonous I think.

No it is not poisonous to bees at the level used for treatment. It is present in rhubarb and other fruits and vegetables. That's is why I flagged the emotive language. Beginners may be put off treating their bees with such language. Oxalic has been extensively researched if people can be bothered to read it. It is a highly acceptable and effective treatment.

Yup - that's the paper that was passed on to me by an older, and much wiser beekeeper. Some pretty good anecdotal evidence there I think

 

[jenkinsbrynmair]

(note that the BBKA Exam Board don't believe it).

But they do believe in sticking matsticks under the crown boards so that's alright then

Thanks for the reference. Couple of further references in the paper too.

Is there some reason why treating Nosema with thymol isn't taken seriously by UK authorities? Is it only that there's no money in marketing treatment with basic substances that anyone could copy?

Probably because they keep listening to the BBKA, and Bayer aren't interested

Here we use oxalic acid mainly by trickling. Temperatures from 2 till 8 celsius. Preferred high humidity - more efficient. Broodless above all( whenever is that at Your place).
I don't connect the trickling for some date in calender, cause if is broodless period there will be no increasing of varroa, damage is done and week here or there doesn't play much. So mainly watching above mentioned conditions. Also here in mid January colonies start with brood, so it must be done before it ( we all treat with oxalic before Christmas, majority in November the rest in December).
Forgot, of course with syringe ( automatic faster), seams of bees ( not the frames - pointless), 5ml per seam ( usually if shorter seam I don't pour full dose), if some drops more I don't bother - had no problems.

Thanks - first post that actually made any sense to me!

Quantity

Use a syringe and it will drip down easily. 5 ml between the frames.
