What's This? UPDATE

This is Wuhan. Notice the brownish spots all over the leaves and what appears to be blistering up on the center left leaf. Anyone seen this before? Out of over 100 plants about the same size this is the only one that has this today. Did not have it yesterday. We had some lite rain just before dark yesterday and full sun this morning. All these plants have spent many days in full sun already. No bugs noted nor any holes in the leaves. The top pic with two photo's is the same Wuhan plant three days ago.






Wuhan on top



Still don't know what it is but it has spread to at least fifteen more and some leaves are
falling off.


It kinda looks like fig rust. http://plantpath.caes.uga.edu/extension/plants/fruitandnuts/commonfigrust.html  Id keep it away from other plants.
 

bump, still looking for any ideas

Looks like rust.starts here in July but if you have got a lot of rain lately.....

Mike,

The newer and smaller leaves don't seem to be effected by what ever caused the older leaves to look like that. Could be nothing.
Maybe when you took them outside they went into shock? Or it was still a bit too chilly earlier?

I remember one time I told my dad to take a couple of my prized figs outside. He placed them directly under the hot sun. The leaves curled up and turned black and fell off. Set me back the full season but I still have those two plants. One of them is my prized Genovese Nero.

I've seen far worse than yours and they sprung right back.

If you have heavy effected leaves then you can remove them but leave the stems on the plants. The stems will fall off after a few days.

Good luck

Willis, lots of rain, hot and humid. What do you do for it if anything?

Rafed, you are correct, no spots on the new leaves. The ones with the spots have been out in the sun for almost eight weeks.

Definitely rust Rust from too much humidity and or rain.
Not common here in spring but with record rains and cool weather it did come and leaves were removed as it's a fungus and will spread.
Go Blackhawks !

Mike,

As a rule our rains start in June and about a month 6 weeks later the varieties that are susceptible to rust start to show it.   It does spread fast and once they have it you can't cure it but you can keep it from spreading to further plants or leaves or getting worse on the leaves it is on.  Copper is what you want to use.  If you don't treat it it cam lead to loss of the leaves.  

After your comments and research, I just sprayed 115 trees with Neem Oil since I had it on hand and it suppose to control  rust. If this doesn't slow its progress
I will obtain some Copper Sulfate or Copper Hydroxide. Also, we just had another 1.75 inches of rain fall in the last two hours.

Hi Mike are your temps cool enough for Neem oil or is it light enough that that doesn't matter?

Today was cool enough, 79 the high due to clouds/showers. The Neem Oil spray itself is pretty light.

Respectfully, I have to disagree with others. It is not Fig Rust, it is- Anthroacnose (Collectotrichum). Symptoms of fig rust usually start from the edges of the leaves, not in the middle. Plus, fig rust's spots (visible fungal colonies) are much smaller and closer together. On the other hand, with Anthroacnose, the dark colored spots are spaced widely and unevenly in the middle of the leaves.

With both disease, I remove the leaves, especially with Anthroacnose, it is much serious than rust. After years of using the Copper sprays, I have came into the conclusion, it doen't work 100% of the time and sometimes it will burn the very young leaves with in 2-3 days of its application. Chlorothalonil (barnd name- Daconil), has worked best for me.

Good luck,
Navid.

Thanks Navid.  I didn't know what this is in Mike's pictures, but I see something that looks similar on a couple of my trees.  

Mike

p.s.  last year I used Neem Oil on a tree that had rust, and it worked pretty well.  I removed the affected leaves, sprayed with Neem Oil (and segregated that tree, and took it out of the heavy sun into a partially shaded spot so it wouldn't burn while the oil was on it).  I resprayed every couple of days.  After about 2 weeks, the new growth seemed OK so I put it back in full sun and stopped spraying.  Seemed to work.  But that was definitely rust, and recognizably different from this other fungus.

Navid, thanks. That appears to be the culprit. Certainly was not aware of this on figs. Have used Daconil for many years on tomatoes etc.

Just an update on this terrible disease. I have sprayed all 125 trees with Daconil. I have also removed all the infected leaves, separated the sick ones and spread all
the young trees out for more air circulation in this 90 degree weather. However, it is very disheartening every morning to have to continue to remove the infected leaves
from what were beautiful, healthy plants. I know they will grow back if the plants survive this. I don't wish this on anyone.

Anthroacnose (Collectotrichum) UPDATE

The top photo in this thread pretty much describes this disease. It moves very quickly from leaf to leaf and probably would infect all
leaves on a three foot tall tree in three days. From my research it appears it could be deadly to the plant.

 I had pretty much gotten it under control by removing the infected leaves and spraying with Daconil as
recommended by Navid. However, after four days of torrential rain (6.15 inches) and absolutely no sunshine, it has returned with a vengeance
over night. This morning there were twenty three plants affected, of them twenty one were one gal pots and two were three gal pots. No five
to 20 gal pots were affected and no buried in ground pots were affected. Only the close community pots were. All infected leaves have been removed
and each plant sprayed with Daconil. If you are in a hot/humid/rainy climate I would suggest you keep an eye out for the symptoms and act
promptly if they appear.
