service berry tree SICK

| On the tree forum, my service berry has been diagnosed with rust and lacebug, from the photos I posted. My question is, can I get rid of these conditions organically? without using harmful to the enviorment chemicals? I imagine I will need to begin some kind of treatment by fall, and then again in the spring. It is a pretty big tree, I imagine though, if I use a hosend sprayer, and stand on a ladder, I can treat the top. |

| As for the rust, it's a matter of environment. So you'd need to ship the tree to a more dry climate. Or you could tolerate the damage. Or you could replace it with a tree that better tolerates the conditions in your region. |

| Well, normally things like this wouldn't bother me, but it is a native tree, and the berries are loved by the birds.Now that is has rust, they can't eat the berries, so I feel that I should correct the problem if possible. We have had a very dry summer thus far, low on rainfall I believe, and it was thriving for 7 years or so until it developed this problem two years ago. |

| The "Amelanchier", Serviceberry, around here get rust every year, just as the "Malus" species do adn it does little to no harm other than look not too good. The birds still eat the berries, without harm to the birds. The Lime/Copper, Bordeaux, sprays are supposed to help but can damage the trees foliage more then the Rust. Since most all rusts need an alternate host, ie, cedar/apple rust, eliminating that, if possible, is an alternative. |

| The birds will not eat the berries once they are coated with the rust substance. The berries just hang there and are now black pellets, hard. what do you mean by the alternate host? What or where would that be? |

| An alternate host is something other than the target tree where the disease develops, an example would be Cedar/Apple rust that needs a Juniperus somewhere nearby, White Pine rust needs a member of the Currant family somewhere nearby. |

| What kind of rust? I was disappointed to see that my serviceberry had cedar-apple rust this year; but then I was looking forward to eating the serviceberries myself :-). (The birds aren't eating the serviceberries on my tree either.) My area is covered with eastern red cedars, so eliminating the host is a hopeless case. On the other hand, my area was also covered with eastern red cedars last year, and the serviceberry didn't have cedar-apple rust. I will wait to see what happens next year. |
