Iris leaves are dropping off at the base of 3 or more plants . Some indication of gnawing on the interior of leaf at the base. Is it crickets? I know I have lots. Would diatomaceous earth help?

Could be snail or slug damage. Go out in the morning and see if you can see them. I'm not sure what cricket chewing would look like but they do eat iris.

Welcome!
Here in the Midwest, when I see leaves slumped over like that, rot can be the culprit.

In this desert I haven't seen slugs or snails. Do see centipedes, crickets.When irises were blooming somehing was chewiwing buds from outside. Thought that was grasshoppers newly hatched. (Used to see slugs in Alaska.)

Maybe I over watered? Soil is clay. Do these leaves look like yours? All are the soil end. Darkest one is dry, does not feel rotten.

With bacterial soft rot, the ends the leaves and the rhizomes are quite mushy. Bacterial soft rot is also very "fragrant" and you would smell something fowl. I'm not familiar with fungal crown rot. The American Iris Society has a brief list of pests and diseases that can impact irises, linked below. I hope that helps. Good luck!

Welcome! Akeleven. I also have clay soil too and I have never had any leaves turn white on the ends like yours.
In your photo above, the damage looks higher than soil level to me and not at the very base of the leaf, so I would guess that it is caused by a critter that can only reach that high, but I it is only a guess.

Look like chewed leaves to me, but no idea what sort of critter could be responsible. Shrug!
