I have 3 tomato plant one beside each other in raised beds and the first one got early blight (many lower leaves infected and some tomatoes have light brown spot on them) but the others seem fine so far so I was wondering if it was logical to pull it out to prevent other tomatoes of catching it too? I have another 10 plants too but in different raised bed next to them.

What i read to do to is to remove the lower leaves of my plants, to remove infected leaves and to spray an anti fungal spray (I heard water and baking soda works) does that seem right?

If i don't pull out the whole plant should i remove affected tomato fruits as well?
