Hives and hazel treatments

[leotordo]

Hello everybody,
in the place where, I hope, next year I will plant my bees there is a beautiful hazel grove. For reasons of exposure, the hives will be in front of it.
The owner tells me he does hazelnut treatments with copper and sulfur (three times per season)
I know that bees go to hazel for pollen at the beginning of the year.
The treatments are carried out starting from the end of April (we are now at the turn of the first) when the fruits are already there (never with flowers)
I have read that there can still be a problem if the chemicals end up on meadow flowers under the treated plants, but in this case just mowing first and the bees should not forage anything.

Question: even in the absence of flowers, can it be a problem? bees have to cross the hazelnut grove to get to the chestnut trees in the cliff just above.

I await your comments, thanks
Stefano

Bordeaux or Burgundy spray, or something else like in this list...?

Bordeaux or Burgundy spray, or something else?

Bordeaux mixture (copper sulphate and quicklime) is now banned in the UK ... not sure about Italy - I'm pretty sure it was an EU directive so Italy should be the same ... it used to be the standare anti-fungal treatment ~ and very effective it was too. Whether or not all the other EU countries followed EU directives as religiously as the UK - juries out on that one !
