Seeds of diseased plants
So my plants came down with what I think is bacterial spot/spec. They're still growing and producing and the tomatoes still turn out ok. But I took some cuttings from parts of the plants that weren't infected yet, they've been rooting in a jar of water for the last 8 days and one is starting to show the same specs/spots. I figured this would've happened but it led to me to think about the seeds i've been saving from these plants.. Would they be compromised as well?

Bacterial speck, spot and canker can all be seed born. Bacterial spot can be removed from seeds by hot water treatment.

My personal practice and I think it is sound advice in all cases is not to save seed from any diseased plant. Seed is pretty easy to come by, especially OP seed and certainly if anyone intends to send seeds to anyone else. For your own personal use, if the variety is important to you then it is up to you. The other trouble is that by saving seeds from diseased plants we are perpetuating that trait of disease susceptibility in future generations. Conversely by saving seed from healthy plants, especially plants that seem to be unaffected by problems besetting other plants in the same garden you are selecting for disease resistance even if in an informal way, which can be very valuable down the road.

I would not risk saving seeds from diseased plants. I only have a short growing season for tomatoes and I would not want to risk losing my plants.
Even if it's a small risk, it would not be worth it to me. Also, if I were you, I might select a variety that is resistant to Bacterial spot for next year and not perpetuate one that has already proved problematic. |

I think that technically, it may be better to save seeds from infected plants, because then you know that the plant had the infection and survived. With an unblemished plant, we can't know whether or not the plant was infected. It could be random chance that caused it to miss getting infected.

Yeah for the most part I started saving seeds before I really noticed they were diseased. Now its really noticeable and im wondering if i should just toss them. thanks for the insight.

It's also well known that some of the soilborne pathogens such as the various fusarium serotypes as well as Verticillium and some others can be seedborne and again,lots of threads here about that it terms of the best ways to get rid of most,never all,of those on the seed coat. Carolyn
