With all the rain we've had, as well as heat and humidity, my iris beds are looking sad. It starts with small yellow spots, then spreads to the whole leaf. Reading about iris, I think it's a fungus, similar to black spot. Anyone else having problems? Any solutions? I've cut back the affected foliage.

You can spray with Daconil. You might want to check them for iris borers too.
