Bean Fungal Disease?

I've started my pole beans for a fall harvest, I'm hoping. I've had some difficulties with diseases on most if not all of the beans I've started. This1 in particular, I have not seen on any except this 1. It is also spreading. I sprayed a copper fungicide on it, but it still seemed to spread over 24 hour period. Does anyone have a clue what this is? I haven't been able to find an answer to this. TIA
