    What exactly do you mean by diseased fruit? Could you describe what it looks like.

  • parts of the individual raspberry are either showing mould or are not ripening

    There are a couple of viruses which can cause misshapen fruit but mouldy fruit is generally caused by grey mould whichs infects at the flower stage.  Are the mouldy fruits lower down and those at the top less affected?  If so, that is likely grey mould.  How long have the rows of canes been there?  If well over 5 years, it would be a good idea to replace them which is the only way to eliminate a possible virus infection.

    A trowel in the hand is worth a thousand lost under a bush.
  • Mine used to have that, I sprayed last year just before the flower opened with the spray for mould & black spot on roses. might just have been lucky but a bumper crop image

  • Thanks for all the advice, will try the black spot spray
