hi, sorry to hear you having problems. unfortunately although i am no expert but from what i have read there is no cure once its started only prevention with a fungicide next time round. be sure to rotate your crops next yr.

the disease you have may not be Botrytis but didymella stem and root rot. The disease attacks the stems of tomatoes at or near ground level but also attacks the fruit as they are ripening. The disease is always at the stem end of the tomato and produces a mould not unlike Botrytis which always occurs in colder but humid conditions.
There are a number of fungicides used but I would recommend that you improve ventilation, remove side shoots and reduce the amount of watering.
