Fungal?

[Cadillactaste]

Noticed something going on with the bottlebrush...when will this tree get a break!?! (((Sigh)))

What healthy new growth should look like.

Noticed on some new growth...

Then some of the mature foliage...

Over all appearance of...my "branch/tree"

powdery mildew?

powdery mildew?

It's mostly black with red tints...but, the black on the old mature leaves did have a bit of white on them. The new growth I just see the fuzz from the leaf...nothing looking like powder. Does it come on without a lot of powder itself?

 

[barrosinc]

That's what it looked like on my tree... seems similar

 

[barrosinc]

I am not an expert but yellow leaves, as I recall, is root problems.

But the white dust might be it?

 

[barrosinc]

Dont take my word on this... wait for a more experienced voice.

We've had a lot of rain...and, I had moved it when we had a bunch of youth doing an overnighter. So in more shade than it should of been. That combined...either leaf spot or powdery mildew I am thinking...off to restudy those leaves. I thought it was just fine hair on the leaves...but, maybe it's more.

 

[Cadillactaste]

Upon closer inspection...the entire tree has fine hairs other than the rough textured trunk. I think the light caught on the hair and gave it the white appearance. I have a bit of hard water spots here and there. But...I am thinking it's this.

Leaf Blotch/ Leaf Spot
Cause: This is a fungal disease that spreads due to the water being too soggy. It affects the beauty and appearance of the tree, and although it does not kill it, the tree looks infected and ill.
Symptoms: Premature defoliation is a good indication that the bottlebrush may be suffering from leaf spot, but since this symptom can also be confused with root rot disease, the other, more telling symptom to look out for, is spots on its leaves. These spots are small when they begin to show, but they increase rapidly in size. They are brown in the center, with a yellowish border around it.
Prevention/ Control: When the leaves fall off, there is still fungus on them, so instead of letting them stay where they fall, it is advisable to rake them and burn them off. This will help prevent the fungus from re-attacking the tree. Spray the tree with liquid copper fungicide. Keep the soil slightly moist instead of wet, and do not over water the tree.

I have had leaf drop of effected leaves...

I pulled it from the pot...and smelled the roots...no odor. Smells like dirt kind of...seriously needs root pruned next year. But no foul odor...

 

[Cadillactaste]

Going to see if I can find some liquid copper fungicide in town. And try that...this poor tree has had so many strikes against it. My moving it into a shadier location and forgetting to relocate didn't help.

I have a huge problem with powdery mildew here. Mine presents as a flat, grayish film, not the raised white shown on the maple leaf. However, powdery mildew may be an umbrella term for several types of fungal infections.

 

[Cadillactaste]

Put a call into my nursery...they have it. And it covers leaf spot and powdery mildew. So either or...I should be good.

If it is not allowing any new growth to grow proper and causing the older growth to wilt and slowly discolor I would suspect it is Fungal and will need treatment like an Apple tree. I cannot see close enough but spider mites often leave a web - like mess and slowly eat the plant in similar fashion. By what I can see though it is probably fungal and the copper works well. Apply it in the evening or morning and WEAR eye protection. I messed up my left eye earlier this year when the breeze shifted and I was not practicing what I so often preach.

Thanks Grimmy...I hadn't given thought to eye protection. No webs...went the round with spider mites with this. This is different. Blaming myself...I should have put it back to its location. And didn't...rain and shade for a sun loving tree...not good.

Don't blame yourself, Fungal issues are caused by weather and can spread even from surrounding woods and orchards. On the bright side copper works

Thanks Grimmy...just feeling like I let this thing down...with all it's had against it. I keep telling myself that it will go from ugly duckling to a beautiful swan. So I keep telling myself. Chanting mishaps can make something in the long term. If you give it the years it needs...but, my husband just shakes his head...and can't believe I just don't toss it in the compost pile.

 

[Cadillactaste]

Good grief...it is in the ravine beside my home...it has hit my pergola as well. My honeysuckle is not looking good...can I hit it also with the fungicide? Guess I need to read the directions...oh...and now my cherry bonsai is showing signs. How does one contain this...when it looks so rapid about ones outdoors!?!

 

[Cadillactaste]

2 tsp = 1 gallon

Then it has a list of plants...some take 3tsp. some 4tsp. So what isn't listed gets the typical mix...others get the additional is what I am gathering.

Example...my silver lace that I got...picked it up. (I don't recall it having it at all now it has it...in being here 24 hours) surely I would have noticed it earlier.)

mildew

hi, im a gardener at a local nursery. the white powdery stuff deff looks like powder mildew. and ive seen the same kind of browning with some plants that get powder mildew but it could also have another fungus going on as well. the powder mildew is a fungus that is usually brought on by over watering or poor air circulation in the roots and branches. the copper funguscide that was suggested would take care of both if you do have another fungus along with the mildew. actinovate is anther product that works really well for dealing with fungus problems. if its in a shady spot, try moving it into a place with a little more light and where it wont be quite as blocked by the wind so it will get more air flow through the branches. hope that helps

Thanks Naomi...it was only there while my husband used the pressure washer and had ladders about and I didn't want gunk from the overspray on it. Then, we had a bunch of teens do an overnighter and I felt it was safer where it was. But it's back into a sunny location. I will keep that in mind...and if I don't have success with what I am using...then I will try it.

But...I don't see any powder residue...more hard water stains, and issues with the black spot in other places now in the yard. Went to town on fungicide even on the trees near the edge of the ravine that our lawn runs beside.

Tomorrow I need a stronger mix for the roses and cherry.

This growing season has made it more difficult then usual treating. It seems almost every time I spray it decides to rain washing the treatment off just to aggravate me At the same time we have been "raided" by Japanese beetles *argh*. On a brighter note it has me really working on ramification more then usual as I am cutting much more then years past. Odd season, grow, treat, kill insects, trim, prune, and plan for a better season next year I guess...
