About two weeks ago I noticed that the bottom leaves on both my purple podded pole and my scarlet runner had this weird sort of red yellow mottling on them. I cut them off, solarized, and threw them in my trash. Today I noticed one of the other tiny lower leaves also looks diseased, this time I wised up and took a picture. I'm sorry the picture is small and blurry, but I'm hoping one of you legume-gurus can ID it for me and suggest what I should do to treat it, if possible.

Thanks for all your help! I dont know how my garden would survive without you all!
