Hot composting may kill the overwintering spores, but there is no guarantee of that, and who wants to have to try to remember where they can and can't risk using their precious compost?
The RHS advice explains the best compost making practice, and is eminently practical because it no doubt recognises that few of us either try or manage to achieve hot composting at all, in which case, apart from allowing pathogens to survive, many perennial weed roots can also live long enough to potentially fight another day.
This year was the third year running I've grown either Wizard field beans or broad beans in more or less the same area, and although they cropped OK, they finished up a blackened, wilting mess thanks to chocolate spot - they went straight in the household waste bin and I'll be growing them somewhere else next year as the spores can overwinter in the soil as well as in the plant material itself.
