It's safe to eat them with lesions as long as you cut the bad part off.

Yes it's safe to eat the tomatoes. If the blight had infected them they'd be rotting

There is nothing you can add to the soil. Late blight does not live in the soil--although some may if you didn't do a thorough cleanup of all plant matter. I hope you did not compost the affected plants or you would be putting the blight in your compost. Any time you have a diseased plant throw it in the garbage. Early blight is caused by the plant staying wet.

The best thing to avoid all fungal diseases when growing tomatoes is to put them in full sun, so they dry off fast after a rain.

Never water the plant only the soil. A depression around the plant will hold and keep water around the roots where you want it.

Always rotate your tomatoes and don't grow them where you grew potatoes--they are of the same plant family.

Buy seed that is disease resistant. The best way to find this out is buy from a seed company. They usually have a list of fungal diseases that variety is resistant to.

Mulching them will not only keep them moist so you avoid blossom end rot but will help with soil borne fungus. by not letting the soil splash on the leaves.

If you see lesions on the leaves pick the infected ones off so it doesn't spread. Now bugs and hornworms are another matter that you will have to deal with.

Tomatoes are really a plant that takes care. If they didn't taste so darn good I think people would stop growing them.

So far as I know, no plant pathogens are human pathogens. I've never heard of a human becoming ill from a tomato virus.

Which is not too surprising, since we parted ways with plants a good few generations past. Even pathogens that infect other mammals exceedingly rarely infect humans. Though the serious diseases arose with animal husbandry.

So a cow is a lot more of a threat as a vector than a tomato-plant.

The Jimster is only partially accurate. There were the eye infections due to contact lens liquid (RENU brand), mostly in Florida IIRC, a few years back, with the infecting agent being fusarium.

Thanks for all the advice. I didn't realize that I could still eat the ones with the lesions, if I cut them off. I didn't compost the plants, they went in my yard waste bin. And I cleaned the pruners with bleach. I was under the impression that late blight was caused by a fungus, because they recommend using antifungal spray to combat it, right? And I do know that some fungi can make you sick, like poisonous mushrooms, which are fungi...Anyhow, just being cautious.

"The Jimster is only partially accurate."

Which is pretty good for me. At least I wasn't totally wrong this time. LOL!

dawiff, you've been warned. Don't get tomato juice on your contacts.
