Chocolate spot broad beans

Hi to all. Advice please. I have managed to grow aguadulce bb in large pots over winter. They are looking lush, loads of flowers, some tiny beans forming. One plant however looks really bad, brown stem and collapsed. I thought it was frost damage but now I see a lot of brown spots on the leaves.

 Do I need to get rid of all compost and sterilise the tubs? I was planning on putting Tomatoes and courgettes in them. I usually would mix in fresh compost and chicken manure and obviously Tom feed, rather than empty 7 huge tubs.  Thanks for any advice.

    I grow Broad beans in the garden not in containers … we occasionally get a little bit of choc spot, not a lot … I quit happily plant tomatoes, squashes and all other fruit and veg in the ground following the beans … never any problem. Most diseases are specific to just the one type of plant. 
    I don’t think you’ll have a problem.
