I have tomatoe plants that start off great, then when they are about

What is the problem and how can I stop this spreading to my other
tomato plants.

My brother who lives 200 kilometres away from me is also having the
same problem.with his tomato plants

Advice would be greatly appreciated.

Thanks.

This sounds like a fungal attack to me though I cannot say which one. Has
the weather been very wet and/or humid lately? There isn't much you can do
immediately except destroy the affected plants (burying away from the vege
garden is good) and replant away from the infected area. Plant with wider
spacing and tie them up religiously to allow air to circulate. Try other
cultivars because some are much more resistent to fungus than others. Also
be careful with watering. Try to keep the leaves dry and just water the
roots and avoid kicking up mud with the hose. Drippers or soakers are good
here instead of sprayers or hosing.
