Re: [nafex] Fire Blight (?)

Doing a bit more work, the malady may be caused by the fungus
Botryosphaeria obtusa - commonly known as 'Black Rot Canker'. "Northern
Spy, Cortland, Gala, Honeycrisp, McIntosh and Empire are most often
infected, although all apple cultivars are susceptible." (ref
http://www.omafra.gov.on.ca/english/crops/facts/blackrot.htm )

I am near the extremity of the cold tolerance for Cox's Orange; this may be
a contributing factor. My tree's location was in partial shade (3 PM on)
and was also competing with a neighbour's large Norway Maple 15 feet away.
I have previously notice the maple's shallow roots infiltrating my area.

I will re-graft the species (my wife's favourite). I have scions available
on another tree and will plant it in a sunnier location.

Thanks for the responses.

Re: [nafex] Fire Blight (?)

John,

I cannot remember the name of this disease, and my reference book is packed
away right now, but this looks like something that was affecting my apples
and pears after several wet cool summers in a row. I think it came in with
a new pear tree. From my memory, it's a fungal disease that affects apples
and pears only, and something I had never heard of before I got it, but I
looked it up in a disease book and was 95% sure I had the ID right. The
bark splits, there is brown discoloration, and it's kind of soft and moist.
Only cure I think was to cut it out well back of any affected spots, burn
it, and hope.

Sorry I can't remember the name! I found it in a book put out by the
extension here.

Good Morning,

I certainly agree with Jim is that does not look like fire. Absolutely
does not. Certainly I'm not an expert on Apple diseases but this looks
to me like sun scald and then fungus set in but not the fire blight
bacteria. As Jim said, fire blight spores leave a black mark that is
washed by the rain from the top down.

Re: [nafex] Fire Blight (?)

It doesn't look like Fire Blight. Fire Blight's characteristic is the
appearance of having been burned (blackened).

Re: [nafex] Advice on disease resistant apples for Charlotte NC

Fluff,
Been growing the apples on your list since 1992. In Bristol, TN, about 150
miles NW of Charlotte.

Williams Pride---Definite. Very cold hardy bloom, great limb angles, but a
tree with upright habit so can get very large. Apples good size and flavor
for being so early. This and Liberty the most reliable year after year,
despite variable spring freezes.

Dayton---Have topworked most of that tree, because flavor was so poor. I
recall Ed Fackler wondering aloud if this one should have been named and
released, at least for him in IN.

Liberty---Along with Williams Pride, never misses. If you pick them on the
green side, will keep for months and flavor up nicely. Barbara, have you
tried this with Liberty? Also, the natural form of the tree, more
spreading, makes it a great climbing tree; one that can easily be pruned,
thinned and picked from the tree instead of a ladder, if rootstock robust
enough. Stem is so short it often pushes fruit off when ripening, so a lot
of drop on this one if left too long.

Goldrush---Jules Janick recommended it as his favorite. Routinely keeps
until Apr. or May for us, flavor and texture my wife's favorite. Least
vigorous tree on the list. Very susceptible to Cedar Apple Rust so will
need to commit to spraying for that, to prevent early defoliation and
subsequent loss of flavor.

Two others that have done well for us are:
---Pristine, ripens with Williams Pride. Canary yellow with good tart
flavor, firm. Apple maggot preferred this one over all others, but were
able to control with sticky traps.

---Kidd's Orange is same season as Liberty. Very dense flesh, great
flavor, excellent keeper for a summer apple, we've eaten it into January.
Have heard it's the best of the Cox's Orange Pippen family for Carolinas
and Georgia; scionwood gifted to me when moving to TN, with the insistence
that it deserves to be more widely grown, at least in our region. I could
make the case for growing this in place of Liberty or Goldrush, though it's
an August apple instead of October as for Goldrush. Have also grafted
Kidd's Orange trees for my farm. One of the few that made the move with us.

All the above save Goldrush with CAR, have been quite resistant to
fireblight, summer rots, CAR, scab, etc.

I have a MonArk tree that keeps getting nailed by spring freezes. Maybe
will get to taste some this year? On the testimony of Lucky and others, am
topworking some seedling trees on my farm with MonArk.

Thankful here for inches and days of rain breaking our spring drought.

[nafex] Advice on disease resistant apples for Charlotte NC

I'm here in the Central Virginia Piedmont, Z7a. Liberty does not
"flavor up" here. I am considering removing it.
Gold Rush died on me. My Williams Pride is still pre-bearing, but I
have great hopes. York and Aunt Rachel have done well, as have
Kinnaird's Choice.

Barbara R.



"I have a growing handful of friends in and around Charlotte NC.

They have expressed some interest in dwarf apple trees and I am not sure
what disease varieties would perform well there.

I am thinking along the lines of early, mid-early, mid and late.

So perhaps Williams Pride, Dayton, Liberty, Gold Rush? I just have no
idea how any varieties will taste in that area. For example I suspect
Liberty may not develop flavor without cool nights but I also here it does
well in warmer climates.

Advice much appreciated.

the fluffy one"
