Fruit Tree Disease Help!

12 years ago

This year I have been going hardcore at my new house. Here is what is brewing on my .25 acre lot:

12 Blueberry bushes

8 Raspberry bushes

3 Blackberry bushes

6 Mint varieties

50 Strawberry plants

2 HoneyCrisp (semi-dwarf) (came potted) (4yr)

1 Golden Delicious (semi-dwarf) (came potted) (3yr)

1 Cinnamon Spice Apple (semi-dwarf) (bare root) (2yr)

1 Chicano Strawberry Apple (semi-dwarf) (bare root) (2yr)

1 Olympic Asian Pear (semi-dwarf) (bare root) (2yr)

1 Yoinashi Asian Pear (semi-dwarf) (bare root) (2yr)

1 Bing Cherry (semi-dwarf) (came potted) (4yr)

1 Rainer Cherry (semi-dwarf) (came potted) (4yr)

The garden was planted last year and I planted all the trees this year and broke my shovel in the process :)

I need some help though with possible diseases my trees may have. Some background: I live in Ohio, and prior to two weeks ago, it rained for about a month! Lots of rain. It is also very windy where I live. Finally, we have clay soil.

Now here are my problems (possibly):

Yoinashi Asian Pear

-------------------

The tips of some leaves are turning black. I don't know if this is fireblight or something else?

HoneyCrisp

----------

Just a few leaves have these rust spots. I figure it is cedar-rust or scab. Thoughts?

Golden Delicious

----------------

Some leaves on various branches are turning yellow. Only thing I can figure is that maybe a pruning I did a week ago caused this? (I know it was late for pruning but I had my reasons). What do you guys think?

Rainer Cherry

-------------

The leaves look torn to bits. To my untrained eye this does not look like disease but rather due to high winds and tons of rain. What do you guys think?

So there you go... I sprayed a non-organic fruit spray on all of the trees before I took the pictures. I have also bought some compost tea and some needle oil (or whatever it is called) but have yet to use them. I wanted to get some advice and comments from you guys first.

Thanks!

likely to be all abiaotic -- not insects or disease.

Yoinashi Asian Pear - not fireblight; instead dry leaf tips/edges
Honey Crisp - not rust
Golden Delicious - Is that a weight on the branch? Is, did the branch crack when pulled down?
Rainer Cherry - recent strong winds? And/or hail?

Your peach has peach leaf curl disease. To control it the plants need to be sprayed late fall and early spring before the buds start to swell. Spraying now will not help. Discarding the diseased leaves might help a little for next year. Use the search feature and you can find plenty of info. We get the same question and pictures regularly. 5% is not serious, don't fret.

Agree with John. Probable time for this one to go. They all hit the ground eventually. Maybe 10 years, may be 400. But they all go for one reason or another. However, also realize this opens the door to replant with something of your choice if you are inclined to do so. Many people here are very happy to help you make a good choice if you choose to plant something. Arktrees

A tree that is ringed (or girdled) is going to die. Nutrients go up the core to the leaves and travel down the bark to the roots. I ringed an annoying big poplar 3 years ago and the silly thing is still alive but it will die. Get new trees.

There are a couple of organic solutions. The first thing you need to do is clean up all the old fruit and throw it away. This fall when the leaves drop spray with copper. In the winter spray with dormant oil spray. In the spring spray with copper a couple of times before the tree comes out of dormancy. For the moment spray with sulphur. In the spring and summer you should spray with sulphur every week. For the insects most organic farmers spray with surround. If you want to grow organic fruit read up on neem oil, serenade, and surround. Consider bagging fruit ( there are YouTube videos) . I'm not an organic fruit grower I am a member of forums organic fruit growers are part of. Good luck hope that gives you a place to get started.

Thanks! As for the cherry tree, there has not been any hail but we have had crazy rain for the past month and we always seem to get a ton of wind.

Regarding the golden delicious, I have anchored the branches down but none of snapped or what not. They are very flimsy almost whisp-like.
