leaf curl on plum trees Help!
My plum tree has leaf curl virus. I now know that it can be prevented by
spraying at leaf fall, and again in spring prior to the buds opening with a fungicide such as bordeaux mixture. However what should I do with the tree at the moment? Should I prune out the affected branches, and feed the tree? or should I just leave it alone and feed it? The tree is a victoria, and I live in the Manchester area, which is quite damp |

The tree is a victoria, and I live in the Manchester area, which is quite damp Bit of confusion creeping in. How did you diagnose the 'virus'? What do you hope to achieve by spraying a fungicide on a suspected virus infection? Have you opened up those curled leaves and looked for aphids? When you have a good diagnosis you can then think what to do about it. Rod Weed my email address to reply http://website.lineone.net/~rodcraddock/index.html |

It only affect the ends of some of the shoots. Leaf curl virus was the nearest match that I could find but I am open to suggestions as to the cause and remedy. |

All I can suggest ATM is to look at http://www.rhs.org.uk/advice/profile...plum_aphid.asp Then have another look at your leaves possibly with a decent hand lens if you can.This really is the prime suspect but it would be nice if you could see the evidence for yourself to confirm it or send us looking in another direction.

The could be the Tortrix moth caterpillar. It's small and hard to spot, IIRC. http://www.birstall.co.uk/trouble43.htm -- Sacha www.hillhousenursery.co.uk South Devon (remove the weeds to email me) |

The picture looks exactly as per the link. On very close inspection with a lens small aphids can be seen (must get eyes tested!). As Murphy Mortegg has now been withdrawn I will have to resort to the fall back of Soapy Water sprayed on the leaves and then rubbed in with a rubber gloved hand. Thanks for all the help. Richard |
