Garden Friends:

I have many Hybrid Iris plants which have not been watered much during the high heat we have had here in Athens, Greece.  I noticed that the leaves are rather pale green with many dead leaves and the remaining leaves have small round spots of brown and yellow, the tips of many of the leaves are brown.  My book says to spray with an appropriate fungicide, but it does not tell me what one or how often.  I have cleaned the beds, pulled all the old dry and very sick leaves
off, cut the brown ends off the leaves and fertilized and watered the beds. Now would like to use a fungicide. What do you suggest?
 
I was going to advise against using fungicide, but two others have beaten me to it.The spots and browning are no more than can be expected in leaves which have suffered prolonged drought and heat and the measures you have already taken should be entirely sufficient to save the plants.
