Hi,
today I discovered these spots on one of my tomato plants.
Could you please help identify the cause?
Should I dig up any plants that get infected?
Does anybody know any possible organic treatment?
Thanks for the help in advance!

Could be leaf spot, could be nothing, it is to early to tell. I would remove the affected leaves and see if anything progresses.
I know I always have to cut the leaves closest to ground off a few weeks after planting, they always seems to get damaged.
Thanks, I'll keep an eye on the plants to see how this develops.
How serious is leaf spot? How much does it affect the harvest?
Mine had septoria leaf spot a couple of years ago. I don't know if yours is the same as mine. The leaves kept dying off, progressively, but the fruits seemed okay. At the end of the season, there were only vines and fruits.
Don't water the leaves, only the soil. Remove leaves if they start to show signs. Don't compost them. Don't plant again next year, in the same area.
