Green Magpie - Sungold will split, regardless. One of the traits of the variety. I stopped growing them, a bit too sweet for my taste, but I used to harvest a tad early to avoid the splitting.
Liz - there's no killing the spores, per se. Burn or bury. A couple of leaves in the compost won't hurt. Tomato fungal spores of any description are only really a hazard to the next crop if the spores make it onto the new foliage.
Fungal spores enter the garden on the breeze. There's no stopping or avoiding them. All you can do is try to minimise their effects via the sort of housekeeping Dove mentioned above.
