Borers in Picea
Hi:
I have found borers on a Picea (A. Nidiformis ... I think) that a friend brought me a couple of weeks ago !! I have read up all I could about it (including all of Nina's old posts) and there seems to be little I can do to erradicate them. Half of the tree is dead (the other half looks weak) so the bark flakes off easily. There I have found some tunels under the bark. Some of them lead or come from a sort of oval depressions. Some of them are blocked with resin as the tree tried to fight this off. I can only find two probable entry points: one is about 3 mm, the other 1 mm in diameter. In only one tunel I have found evidence of being recent. The question is: Should I forget about this tree? Does the tree have a chance? I know it is hard to say, but what does your experience tell? I don't even know if these "miners" are active or not. Some pictures at : http://es.pg.photos.yahoo.com/ph/ast...bum?.dir=/3d01 I don't know if I should worry much about borers spreading. I live in a countryside where most trees of some age seem to be affected by borers and flat-big headed larvae living beneath bark. Regards, Tony Zone 10a |

well I read the whole mail I guess it is better you destroy your tree
burn it it is in a very advanced stage . avoid contact and contamination with the your otehrs bonsai and environment of the place you live probaly other people will tell ya the same Tony wrote: Hi: I have found borers on a Picea (A.

Borers don't attack healthy trees; this tree was already under some kind of serious stress when the borers found it. Especially if these are bark borers (NOT going into dead wood) you probably don't have a prayer of saving the tree. Unless you have other spruce (or closely related species) the borer may not attack your other trees. And again, they'll have to be doing poorly first -- though the stress of a drastic root pruning could be enough.

When I found mine borers in the maple I telephoned to the forestal and
agricultural school at Lullier- Geneva and asked for advice and they told me to use Marshall( that incidentally I had , and inject in the holes as I already said first of all I tried to dig out the borer with a thin wire copper oo aluminium for bonsai and tried different directions .. I noticed that it had borers as I found some sow dust on the soil in two different moments of the day.. and I knew that should have not been there after cleaning as much as I could the holes that passed trought the neabari I sealed them with beewax.. The Marshal product is given by watering and absorbed by the tree poisoning the bark wood so borers eat it and die .. Tony wrote: Hi: I have found borers on a Picea (A. Nidiformis ...

Yet I must repeat, as I have 10,000 times, that borers are a sign of stress, and in your case, the stress is tropical conditions on a boreal species. Next time it might be a botryosphaeria canker... there are lots of organisms that will attack a stressed tree, but not a healthy tree. That being said, if you don't mind dead-wood, you can carve out borers. I had an apricot bonsai that got plum borer (a borer that can only penetrate at a pruning wound, so can be prevented once you know what's going on). I successfully eradicated the borers and the tree thrived, but the surgery I did looked ridiculous on a non-conifer, so I gave up and planted the tree. As soon as I find a good source of single-white blossom flowering apricots, I'll try again, because I love apricot flowers. There's something so pretty about such delicate, fragrant flowers blooming so early against a background of black bark. Nina |

Nina I don't have any experience with this type of borer, but I had them for a couple of years on some collected wild crabapples. I just carved out the tunnels they had made and turned them into areas of deadwood. Adds to the character.
