hi,

I've just noticed that there are black spots on the leaves from my tomato plants. would anybody know what these come from, if they are bad for the plant and what I need to do about it?

Thanks,
Frank

looks like water droplet scorch caused by the heat of the sun acting as a magnifying glass on a water droplet. it does not look like a disease caused by a pathogen and i am not familiar with it. it will probably grow out of the problem. Check the underside of the leaf for moulds and if they are present then cut off damaged leaf so as to limit the spread.
