Disease and composting

My broad beans first  got brown spotted leaves and then the stalks and lower pods went black .

1. What disease have they got? and

2. Should I compost the stalks or will it leave disease in my compost?

Thank you for any advice.

    Don't know what the black spots are but the golden rule is never put diseased material in the home compost bin-burn it or domestic rubbish bin.

    Sounds like Chocolate Spot - very common on broad beans especially in cool damp summers but doesn't usually affect the eating quality of the beans and doesn't infect any other plants.  I wouldn't worry about adding the haulms to the compost - allotmenteers I know have been doing it for years with no noticeable ill effect.

    It is said that it may help to avoid Chocolate Spot if you can plant your beans a bit further apart to allow good ventilation - and of course this is try of other fungal diseases too.

    Thank you for your advice.  I will plant the beans further apart next year.
