I use the neem oil, but once its going too strong... I have to pull infected plants.
Air circulation as others mentioned is MUCHO important!
Just remember, the mildew will spread quickly between cukes... squash... melons....
So try not to intermingle those plants in the same bed to cut down on spreading.
**I think its actually downey mildew**

You could probably benefit from some increased air circulation in there... Can you open windows, or use a fan. I would get the plants out. IMO, you won't need to treat the soil. Were your plants crowded in there?
Yes, thank you, the windows are open and I have a temp controlled exhaust fan. I have no idea how this 'crud' got in there! No not at all crowded. The hanging plants (cherry tomatoes) are just fine. The only ones affected are those in contact with the greenhouse soil. It doesn't affect any herbs either. I removed the plants (seedlings) that were in Jiffy pots (they still look terrible) BUT the few I set out in the garden area seem to be thriving. ???? The plants that are planted in the soil (in the greenhouse) are toast

Cason, your problem reminds me of some that we had in the commercial greenhouses where I worked back in the Pleistocene.
First of all, if we had a soil pathogen - we would dig out the bed to about a 6" depth and then bury a flexible steam pipe. Steam running thru that pipe would sterilize the soil overnight. The stench was horrible but the treatment was effective. (I don't think this is likely to be an option for you.)
We had one old greenhouse where the soil was so seriously contaminated with copper that the level of that element had reached near toxic levels. You may be able to replace all the surface soil in your greenhouse but management resisted that idea.
All growing became essentially hydroponic in those greenhouses, sometime after I left. They used concrete trenches and peat bales but I really knew nothing about the conversion and all that.
