Maximum Residue Levelwhat is MRL's (ppm)?
Many thanksMaximum Residue Level
The idea is beautifull but has no practical meaning.but I do believe that every time you treat a colony, you delay the co-adaptation process a little.

Today I did! It's persisiting down!Norm,
You probably don't need a coat in Spain. Unless you are in Galicia!
As I mentioned, not for everyone, but your selection process is skewed by your own imaginings of what are the 'best' bees to breed from. 'Live and let Die' allows nature to select. I once heard brother Adam say that only nature selects for survival. That stuck with me and I feel is very apt in this situation.I agree, wholeheartedly. But I like to try to select rather than let them all take their chances. Yet another reason why I only treat with OA when necessary.

I was told the same that my bees would die in the first, second, third year but I still have them, I do practise smaller cell and natural in the brood box, one beekeeper been in it 30 plus years lost all his hives last winter and he use to rotate treatments from year to year (poor bees) the has started to shown some interest in the way I keep mineAt the risk of being controversial, I would add a further approach to dealing with varroa, a do nothing policy otherwise known as 'Live and Let Die'. This one is not for the feint hearted as you have to expect severe losses if your stocks still have vulnerable genetics. My belief is that most of the very vulnerable bees have long since gone! I have adopted this approach for various reasons but the reality is I am still having some success since they were last treated in 2007. I am not going to start quoting anybody elses work, just my own experience, but there are many other beekeepers who are saying they too are having success with this approach. I was told initially that all my bees would be dead within the first season. Then, when most were still going strong in the second season, I was informed that they would soon crash with mite driven viruses etc. etc. Recently I was told that they will perhaps crash in the third season. I am in that third season now. The losses I have incurred last summer were down to comb collapse in the unusually hot summer, not varroa as far as I could establish. I am not advocating this for everybody but I do believe that every time you treat a colony, you delay the co-adaptation process a little.
OK, I have lit the blue touch paper, is it time to get my coat???

We have had resistant varroa in the South West longer than anyone in the the UK. Last year I heard someone tried Apistan on some hives and found it knocked down quite a few mites. However, they then followed up with Apiguard and found about the same number of mites knocked down. In other words the Apistan was only about 50% effective. This was on a hive which had not seen a synthetic pyrethroid treatment for at least 3 years.one beekeeper been in it 30 plus years lost all his hives last winter and he use to rotate treatments from year to year
I think you are right, a never ask this beekeeper if he melted all that old wax down and sent it into one of the bee suppliers to be reused in to brood wax again.It may be residues from the treatment remaining in the wax mean the mites are never really free of the chemical and therefore continued exposure to it maintains resistance.
