    Runner bean rust

    I've had rust (Uromyces appendiculatus) on my runner bean leaves for a long time now and, as I always do, I've just ignored it.

    However this year it has got extremely bad and since the plants are still cropping plenty of pods and lots more have been left to produce dried beans I am wondering if anyone has a method that might slow or control its spread.

    I don't think commercial fungicides are appropriate for such an edible plant so any eco-friendly suggestions would be most welcome.
    The proof of the growing is in the eating.
    Leave Rotten Fruit.
    Nitrogen, Phosphorus, Potasium - potash.

    So, it's really bad, but not affecting the yield?

      I meant that it has got really bad this last week or so. Much worse than I've ever seen rust.

      I'm worried that it might START to affect the yield, especially the dried beans.

        Well it's autumn and the end of the plant's natural life anyway, so your yield isn't going to increase any, rust or no rust.

          If that's not what you want to hear, read the first para of this RHS link:

            I have only experienced it a few times and found that the later you plant the beans the more susceptible they are.

            I sow my runners on May Day and touch wood no problems. General advice says dont save the beans but as it is spread by spores I struggle to see the connection
