It has been the cloudiest spring I can recall.  Very dark, humid, and rainy day after day.

I was terrified of getting rust, because I had some on the fig trees at the top of the hill last year and it's very sad to see your favorite trees loose their leaves when they should be growing.

I treated about a quarter of them on Saturday with liquid copper.  The ironic thing is now some of the leaves look like they have rust when they didn't before.  

I made a very big mistake and used Tablespoons instead of Teaspoons when measuring.  And to think, I worked years in biotech field were precise measurements were imperative.

 So I think it's time I finally get those bifocals I have been putting off because I think I don't need them...

Don, I have started to develop the same thing on some of my leaves after the past 4 weeks of rainy cool weather.  I think it is some sort of fungus that will likely disappear once the sun and warmth comes back.

Don, other than the dark spots those leaves look nice and green, it may be just the overdose, i think they will be fine

Yes your right Johnny, it looks just like rust.

But here's the thing, these leaves looked fine until I sprayed them with 3X the recommended amount of copper.

I think you can't get more ironic than that.  :)

Hi Don
They looked like very nice healthy fig plants.  I am sure the will be OK.

It does look damage from the copper spray.  Some plants are sensitive to copper. 
I don't know if figs are sensitive to copper or the 3X the recommended rate did it.
Also the time of day you sprayed (i.e. full sun) could have contrinbuted.  Better spraying in morning or late day never in noon day sun.

I found that air circulation through out the tree helps prevent rust.
I remove leaves that restrict air movement to allow good circulation.
I have never had to spray for rust and rarely run into it.
The few leaves I remove near the stalk has never caused a issue either.
Just something to consider.
