Septoria or something else? Control?

tam91 · June 1, 2020

Hi all - looking for some help with disease ID.

Tomato plants have only been planted out a couple weeks, seeing these spots on lots of them.

Oddly, there is difficulty finding Daconil (even generic chlorothalonil) or Mancozeb around here at the moment - I may have to order something online, so I want to try to make the best choice.

Suggestions please?

Flea beetle damage! Don't worry about them as they won't damage the plant. They usually just go away

Hmm well that's a new one for me - thank you.

Reading up on them - it does sound like maybe they can kill small plants - are we sure I don't need to worry?

And if I do need to worry - what can I use to kill them? I'm not organic, so not worried about that part.

Carbaryl (Sevin) dusting will kill and repel flea beetles. I use very little chemicals, but every once in a while it is necessary to save a crop.

I just used Permethrin spray on all my cucumber, bean, tomato, and pepper plants due to a huge outbreak of flea beetles. I usually have to do this at least once or twice every spring. I also spray the mulch lightly under all my plants to kill as many as I can. It doesn't seem to harm any of the plants and they usually look much better in just a day or two without those little pests sucking the life out of them.

I don't know why anyone would use Sevin these days. It's carcinogenic and kills the bees, but I guess people don't care

Thanks, I think I probably have some of that. These plants were reasonable size transplants, but not huge.

I had flea beetles on my eggplants and I am organic so I used some Neem spray and it worked. Neem does also kill bees so I use it in the evening and the eggplants are not flowering.
