I noticed this morning that four of my eight tomato plants have these spots on some of their leaves. Any help would be greatly appreciated

Not sure if this is exactly what you have, but this is what I found after a quick search. Looks like you'll be ok.

One of the common tomato maladies is Septoria leaf spot. It is a fungal disease that affects the leaves, but not the fruit. The first leaves that are affected are typically toward the bottom of the plant. The leaves develop small, dark spots that rapidly enlarge to 0.25 inches and have a tan or gray center.

Tomatoes are prone to a lot of bacterial and fungal diseases, especially when it's hot, humid and they are closely planted.

When you water your plants, only water the bottom by the soil and not the entire plant to help keep as much moisture off the foliage as possible which can lead to fungal issues.

If those are just on the bottom then mine get that every year. Slowly creeps way up plant and by early August they are toast. No deal as I get plenty of maters anyway.

So this season I pulled out the oral b electric toothbrush and run the brush while on around the blossoms. I can't believe I've never done this before. Most of the blossoms have fruit.

There is merit to this to assist in pollinating the flowers into producing fruit.

I have a problem with squash vine borers every time I plant and try to grow squash. One year I decided to use row cover to protect the plants from the pests that lay the eggs that turn into vine borers and had to hand pollinate the flowers to produce squash since bees couldn't get to the plants to do the job.

Septoria leaf spot.


That’s what it looks like. Rotate Liquid copper and Daconil. Should help prevent spreading.

Yeah, this. I don't use the Liquid Copper but do spray Daconil every 7-10 days. Every once in awhile if it's rained within a few days of spraying Daconil I got some organic 3 in 1 fungicide crap I'll spray on it.

Leaf spot hit my plants within a week of planting. So far I'm only having to pull off maybe 1-2 leaves every week and a half to 2 weeks on the plants. Daconil works great, but I've been spraying it since early April, not sure how long it will keep working, maybe I should take the advice quoted and get some Liquid copper.

I’m dealing with this right now and am using the cheap electric toothbrush method for tomatoes and peppers, and hand picking male flowers to pollinate the squash and cucumbers. The biggest difference I’ve noticed is in the tomatoes, nearly every single blossom is setting fruit if I do my part. It’s a pretty simple thing but I definitely overlooked it in the past.

Looks like "early blight " op. Treat with the fungicides listed above. I'm having the same issue. Pull off the bottom leaves that get very yellow and throw away.
I have lots of maters but my second crop will be weak. This crap spread to my blooms as well. I should have treated my beds prior to planting, and I planted too many plants to close together. My neighbor who sells tomatoes commercially recommended I burn the beds when growing season is done to kill off any fungus that stays.

So what specifally are you doing? Toothbrush on the flowers directly? Just curious and want to try

Just hit the common stem of all the blossoms for a few seconds. Each blossom contains pollen and a stigma so all you’re trying to do is knock the pollen around a bit within the flower. Helps when dry, and I do it when I get home from work. You can do the same thing by shaking the plant, or just thumping the common stem, but the toothbrush is fail-proof. It mimics the vibration of a bee.

Squash-type plants have flowers of either sex so pollinating them is a little more involved.
