Er, no. When they are in flower is just when you *shouldn't* spray!

The books that I have (including RHS ones) all advise that the time to
spray grapes against botrytis is when they are in flower. Mind you,
they are a little old and advise spraying with fungicides that are no
longer available and make no mention of Bordeaux mixture. What is your
reason for advising against it, please?


"Spray the vines with the above mixture (Bordeaux Mixture, Dithane and
Maxicrop) every two weeks until flowering when all spraying must cease."

Thanks. I re-checked my book and they all refer to spraying with Benlate
at flowering. From what you are saying, I presume that I have now missed
the opportunity to spray with Bordeaux mixture and will have to wait
till next winter.
