Thanks Camprn - that was an excellent PDF on Bean Diseases.  I have saved it and hope I never have to use it.  Wish it had more discussion of control of the various diseases (ie fungicides etc) but this should help to identify the disease.  They did give a lot of control information about good practices, rotation, etc.

Something new this year.  White freckles.  I looked in the link posted above but didn't see it.  The beans are fine.

That looks like insect damage. Spider mite probably.

I used the insect loupe and couldn't see any. But it is getting that time of year! I'll go ahead and treat as-though.

Also looks similar to some powdery mildew I saw last year on my tomatoes.  It was very destructive to everything it came into contact with, even the weeds. The yellow/brown spots were the first thing I saw, then the leaves started getting some grayish-white dusty substance all over them - hence the term "powdery mildew" I suppose.  Are beans susceptible to that?  I used copper fungicide to control it.

Update: I happened to see campern's link to the bean diseases pdf, and I probably should have looked at that before posting.  Beans can get powdery mildew, but it has a different appearance on bean plants apparently.  I defer to those with more expertise!  jocolor
