Safe fungicide for using around chickens?

[Indigosands]

I searched but couldn't find anything.. I normally use neem oil but I'm late getting started this year and in our last cold spell some early blight popped up on my paste tomatoes. I need a cure not a preventative now. What's safe to use around my chickens? They have an extensive run, so if it's something I have to keep them out of for a week or two that's ok and I can keep them out of the garden.

Benomyl is a good fungicide. You can get it in most garden centers.
Also natural remedy for mildew on plants like lilac and squash is 1/4 c baking soda and 1/2 cup milk in one quart of water and sprayed with a pump sprayer.
