Good News, Bad News

The good news: some mature beans.

 The bad news: something's attacking the plants.

And withering the beans on the vine.

Should I harvest them green & dry them out of the pods? Or wait & hope?

Elaine: Crap! Guy, I'm so sorry. I looked around on the internets (as I'm sure you did) and found this guide to bean plant ailments on PlantVillage. I hope it helps.
