Black blotches on snap beans

I've gotten a lot of calls about black blotches on snap beans, like white half runners. The culprit is probably anthracnose, a fungal disease.

What to do: most people don't want to eat things that look like this. Get the beans on a good spray schedule with chlorothalonil (Daconil or Funginil).

This disease is mostly seed-borne so be sure you start with clean seed.
