I think I have Septoria

You should ask Redbaron - Bill. He is the real expert.

Gosh I'm not sure with different kinds of Mancozeb. I just went to the garden store, and it was on the shelf. Any one that says it is for tomatoes should be fine I would think.

I had tried chlorothalonil (Daconil), which works for most of the fungal stuff for me, but it did not control the septoria.

Bad timing, I had a whole bunch that I was getting desperate for someone to give them a good home too but they are all gone now.

Clarification please. Did you mean Redbaron -Scott, or b54red -Bill?

Whoops! b54red -Bill

Thanks for the praise Scott but I am no expert. I just live in a very disease ridden area due to the long term commercial growing of tomatoes around here and our wonderfully steamy climate. I'm still trying to find a fungicide that is available to the home gardener that is really effective in preventing Gray Mold and so far I haven't found one. Like gray mold Septoria is really hard to stop once it takes hold so prevention is key. The bleach spray has saved my season more than a few times and has been responsible for much longer and healthier tomato growing seasons for me. Learning to use it was just trial and error with a little desperation mixed in.

Bill, Have you tried spraying Greencure?

[b54red]

No I haven't tried it.

I went back to the top to read this thread and saw that Elliot said black Spots. That's not Septoria Leaf Spot. It speaks more to Bacterial Speck or Spot.

And in post #3 Feldon mentioned Bacterial Speck and Spot.

Foliage diseases due to fungal diseases such as Early Blight and Septoria can be prevented, or lessened, by spraying with a good anti-fungal. But it's very difficult to find something that is that effective against the bacterial foliage diseases.

Elliot, I don't want to lose this post if I go back up and check your initial post but didn't you say it was just one plant that was affected? Foliage diseases are spread by wind and embedded in raindrops, so I wouldn't expect to have just ONE plant affected.

But do correct me if I'm wrong about it being just one plant, bad memory problem here.

Carolyn, thanks for your input on this. I am really concerned because this is hitting my plants very early in the season. Yes, it hit all three of my tomato plants. TWo were sweet 100 and the other grape. They are all in pots next to each other. What I did was to remove the infected leaves and I sprayed with a copper based spray and have my fingers and toes all crossed and hoping for the best. I took a picture and will try to upload it.

Here is my spraying regime, inspired by Bill (I haven't yet tried the bleach solution):

Round 1: Actinovate/Exel LG/ molassas mix. Actinovate. For normal application use ½ -1 tsp per gallon of water. 2 grams per gallon of water (or 1/2 teaspoon) is the recommended rate for the Actinovate solution, both for soil application and foliar spray. 3 TBS/gallon Exel. 3 TBS/gallon molasses in half cup of warm water.

Round 2 (every other week): Daconil in solution – 1 TBS/gallon

I also pick off the yellow leaves and any other problems as fast as I see them (throw them into your house trash, away from your garden), wash my tools frequently with bleach solution, and wash my hands after touching any problem leaf. I find that fast action and good hygiene really slows down spread.
