Judith was asking in another thread if a spray called Vitex still exists

apparently there's something rather new called Benthiavalicarb which is

for this. What it's marketing name is, I don't know but it might be
worth
asked a nursery that deals a lot in grapevines, such as Read's. The herb
Vitex is Agnus Castus and seems to be a sort of herbal Viagra! ;-)

I saw some Vitex "Bordeaux Mixture" the other day, is that what Judith
wants?

"Organic farming also still allows the use of Bordeaux mixture, the
most toxic and persistent pesticide in common use, just
because it is 'traditional'."

It's a fungicide not a pesticide. Persistant in that the copper sticks
around for a long time and is cumulative. There is not a lot of difference
between Bordeaux mixture and the other still availale compound Cheshunt.
