You are welcome
i see, nevertheless a good series. Thanks forvbackground. I live in a wine region, too (especially red wine) and have never seen that in austria. (i think, it´s not that wet here)
exactly!
Galicia, in the nothwest corner of spain is very wet and it is a difficult place for wine, specially for red wine, with a lot of problems with fungal diseases like mildew. Two years ago was very bad for wine, very wet, and the vineyard owners spread huge amounts of copper sulphate so the leaves look very bluish.
So it´s not typical for the species, but only by human use of fungizide?
Yes HansNew, the mixing of blue and green colours looks very strange.
The blue color is copper sulphate, which is used as a fungicide to control mildew.
the blue spots are really strange, looks great
