Id say early blight, but I sense a trick.

It kinda looks like EB, but it's not. A hint: these are tunnel tomatoes.

Advanced powdery mildew?

Looks like EB to me also. So what is it?

It is Botrytis or gray mold. It started from bird droppings on the foliage.

Drat. Got to the thread late. I was gonna guess that something dripped on the leaf - something like bird poop or bleach. The mold would be an opportunistic infection of already-disrupted cells.

Good teaser.

What identifies this as gray mold for you? It sure looks like EB to me.

The blighting originates from bird droppings on the leaf, and every morning there was fuzzy gray mold growing on on infection sites. Then, there isn't that multitude of small brown spots with concentric rings as seen with Alternaria.

Bird droppings themselves could cause the browning since there is a lot of ammonia in fresh droppings you could just be seeing the results of the burn from it. I don't see any sign of what I know gray mold to look like. If it were gray mold it would spread rather rapidly if the conditions are humid or damp.

Check this link out, Bill. I agree it's not "classic" gray mold, but it is. That's one reason I put this thread up because it looks like EB.
