is this fireblight on Quince?

armyofda12mnkeys(7a, Philly, PA)May 18, 2012

Hey all,

Noticed some browning of my quince trees leaves on a few branches. Wasnt sure if it is fireblight or something else. Can anyone identify? I sprayed them with copper fungicide late winter/early spring, thought that could attempt to control fireblight.

Here are some pics to help identify (took them as sun setting so some not focused well, can try to take some better ones tomorrow after work if needed):

Thanks all!,

Ari

Whatever it is, I've got the same thing on my two quinces. Earlier in the year I pruned out branch tips that had obvious fireblight (black, limp). Then I pruned out all the branches that had cedar-quince rust. If this disease requires pruning I may never see fruit on these trees/bushes.

I believe this leaf browning is caused by fireblight. Fireblight has many different appearance modes and this is one of them. The reason why I am fairly certain that this is fireblight is it always shows up along with fireblight strikes of the more standard shepherds crook. I should probably be pulling these off but they don't look infectious to me so I usually just leave them.
