Spots on bean plants

Asked July 28, 2019, 1:00 PM EDT

Attached is a photo of my bush bean plant leaves. Can these be saved? Anything I can do in the future to avoid?

Hi This looks like a type of leaf spot either from a bacterial or fungal pathogen. I would not be able to tell you which one without you sending it in to our lab for tissue culture testing. I would not recommend this type of testing for a backyard gardener as it is cost prohibitive compared to the cost of the plants. Here is a link to some suggestions for management of this sort of problem on beans. I am not confirming it is this specific type of disease but the cultural controls would be the same type of management:
