Pear Leaf Browning (forum)

Firefly1 starts with ...
I would appreciate if I can obtain identification of the problem with my pear tree leaves. It is not a actual image of my leaves but identical to what is happening. I haven't been able to find out exactly what it is and how to treat via Google.

Its winter and they will all fall off till spring - very normal

If you had this issue over summer i would follow the advice below with copperoxychloride spray.

I guess it's a fungus called Venturia pirina.

You have to clean up the dead leaves from the floor and if that's not enough you can spray sulfur.

Thank you - Yes it appears that the fungus is the problem - now I have a name - I will definitely strip the trees of the infected leaves and pick up all others and spray - I see that it will over winter on the stems and leaf buds. Hopefully I can get rid of it before spring. It arrived on the second pear tree I purchased and not having ever had a pear tree, I was oblivious to what it really was and hence it infected my first healthy tree :( Fruit growing is a learning curve that's for sure. Thank you everyone for your input, appreciated.

Firefly -- Until you can post an actual photo of the leaves we truly cant assess. Another issue in summer there is a mite that disfigures leaves and regular spraying of Success Ultra and removing affected leaves works for that problem - If your leaves look anything like that photo theres absolutely nothing wrong with them - I have a Dwarf pear 5 years old and 2mt tall and the leaves look exactly the same as winter hits - it has no leaves now so cant show you and mine hasnt got that mite issue i saw on a friends pear that took 2 years to 90% get rid of.

PS - these photos were taken today - our climate is warm, so the leaves haven't start to fall yet. A couple of leaves are showing signs of some autumn tone.

It is late holding onto the leaves still but it is feeling some cold and retreating into dormancy as it should & has to.
You could still do a copperoxy spray to run off if concerned all over. I saw deciduous trees growing in Singapore (Gardens by the bay glasshouse) and they looked really stressed as they dont get winter and short daylight days.

Thanks I will do that. They were planted last year and seem to struggle with the concept of winter and it wasn't until late winter mid August that all the leaves fell off. I have a Hood and Flordahome which are both low chill varieties. All the leaves have fallen from the Almond, but the pears seem to fight it. Its a gamble but well worth it if I can get them to crop. Thanks for your assistance - I'm keen to keep my new orchard in the best of health.
