Sounds like a question for the grow your own section

I'll split it off and move it to the Grow Your Own section, Chrissie 

Edit: and now it's arrived, you might find that this thread has a possible answer?

It is the plum moth.  I sprayed just before the blossom opened as I heard thet it helps but 90% of mine have been affected.

I've always sprayed when the blossom is open. However, the RHS say that none of the pesticides available to us lowly home gardeners is effective.

I put up a pheromone trap each year.  The instructions with the pack say that if you catch a large number of moths you should back it up by spraying with any garden insecticide a week later.  I did this one year and we got our best crop of plums ever.  This year there were not many moths caught, so I did not spray.  So far I can see little damage, but the plums are not ripe yet...

Cheers,

The neighbour used to put out pheremone (sp?) traps which caught a lot of plum moth but i have never bothered. No traps out this year as the next doors tree has died but we have had a dozen ripe plums from our tree already and not a single maggot in sight which is suprising as the maggoty ones normally ripen first . If you give the tree a good shake when the first fruit ripens the maggoty plums will drop off leaving the sound fruit behind.

Hopefully the last cold winter will have killed a lot of moths.
