What is this
« on: March 13, 2010, 09:30 AM »
Can anyone tell me what this is?  It all over one of my Eastern Red Cedar (j. Viginian) but only this tree not on any of the others or other trees.  Its an orange jello fugus.  It from bottom to top of tree and just came up in last day or two.  Does it pose a danger to my Bonsai?

I haven't had much experience identifying diseases/fungi on my trees so I can't be of much help.  If you haven't already, I would certainly sequester this tree until its identified and treated.

Hopefully you'll get it ID'd soon.

No expert but here is my guess - it is a rust. Three rust diseases seen most often are on eastern red cedar are the cedar-apple rust, hawthorn rust, and quince rust. The most common is cedar-apple rust. On Juniper the first two diseases form galls and orange jelly-like horns in spring. The horns are most likely to form following periods of rainy, warm weather. Spores formed in the horns infect the alternate host. The diseases are more serious on the alternate host than Juniper. Prune out the spore horns when seen in the spring. Do not plant near hawthorns, apples, or crabapples.

Thanks for yalls help.

Research I've done I think is Quince cedar rust.   

This is on the bark of the tree.  There are no Galls on the tree is reason I belive its Quince Cedar Rust.  From what I've read it really does not hurt the cedar tree only fuiting trees that the second cyle delvelops problems that kills the other fruiting tree.

"From what I've read it really does not hurt the cedar tree only fuiting trees that the second cyle delvelops problems that kills the other fruiting tree."

Which kind of begs the question of what the "other" host tree is. Apparently this rust  can have a number of hosts, including hawthorne, apple and crabapple. If you have one of those in your yard, or your neighbor has one, it's probably not a good thing for it...

Bubbafrga,
I first saw your photos on facebook, and it immediately said rust to me. Am I mistaken or is this a landscape tree? As far as I know, the only real way to stop this is to remove one of the hosts. Even then it doesn't really go away, it just doesn't manifest any more.

Chris this is a tree in my "Wild" section of my yard behind my storage shed.  Its about 30 feet tall.  All the "rust" is now gone / dried up and dropped off.   

I have four pear trees in my yard that I just been putting off cutting them down.  Just because I'm lazy.  They haven't really produce any fruit in years.  Each tree only sets about 30 fruit and the tree rats get to them before they rippen. 

My wife did plant 4 kinds of Flowering Qunice in yard last year so it might have came from them, becuase there are no Galls on the tree as in with the apple Rust.

My main concern was if it would kill this tree and my Juniper Bonsai.  From what I have read the cedar is just a host and doesn't really hurt it.   Am I worng?

The footpringtof an infected tree (spores travel freely) is often about 1 mile- according to coop extension. So, it probably doesn't really matter what you do, other than try to control it on your bonsai and ornamentals with chemistry.

It is a danger to both hosts--fruit trees and other trees in the apple family-hawthorne, quince and crab apple. It can also kill off twigs and finer growth on junipers... It is hardly gone just because the rust patches have dried up. It is carried by spores--which have to be dry to be transferred by the wind...
