Fungal? Orange Yellow leaves

[Guavatone]

Thanks.. Wow! Everyone’s saying bleach. Tspn/gallon? Bleach scares me... it really works?

I thought too much water was slightly yellow? Are you sure it’s #4?

They seem happy with last nights Foliar aspirin.

Yep, picture #4 shows bumps on the stem. They are called 'root initials'. If the stem was to touch soil/mix, those bumps would grow roots. It's an easy way to see overwatering.

Great tip. Thanks salt. I thought you were going by the shriveled up leaves. I guess I need to let the containers get dry to the verge of wilting.

Do hairs on the stems also mean too much water?

If it is it is almost certainly gray mold. Late Blight usually starts much higher up the plant at least it always has when I have been hit by it. If I had that few yellow leaves each year I would be very happy. Just remove them along with any other damaged or diseased leaves when you first spot them and apply a fungicide to lessen the severity of new diseases coming along.

Thanks Bill. It’s not black. I think it may be moskvich or cosmonaut volkov

I have a plant 3-4 feet away having similar wilt. And still getting yellow/orange on middle branches on 1-2 and haven’t watered since Thursday rain

Early blight and/or septoria - happens every year in humid, warm areas. Best to just remove blemished foliage, space plants appropriately. If you keep up with it, it doesn't kill plants. But the spores are on the backside of the foliage and can spread.

Thanks NC! I think i’m Going to follow Bill’s advice on Clorox and try it on one plant.

[nctomatoman]

I find that the very best thing to do is just remove any lower foliage with blemishes. If you can keep ahead of it, there is no need to spray - but that is just my approach (I've never really sprayed anything on my plants ever, but I have the time to attend to them)

Thank you Craig. For whatever it might be worth, I agree with you. I did buy and read your Epic Tomatoes book.

I guess this is you Craig/NC?

I’m such a noob, but i’m trying to learn

He's a mentor.

Some plants are spaced 1 foot, some 2 feet. I just saw the video from the link I posted and it seems I have some similarities to Craig’s set up. I’m growing on a cement patio in square foot milk crates with landscape fabric lining the containers. 2 crates stacked on top of each other. The top crate has no fabric on the bottom so that the roots can make their way through to the bottom crate.

Now that I can see the leaves clearly it looks like Early Blight to me. I agree about removing the leaves but would also apply Daconil. It seems to work the best of any of the fungicides I have tried on Early Blight. If it is Septoria I would use a copper spray.

I had a fairly bad outbreak of Early Blight and lost some fruit to sun scald because I had to remove so many leaves. It sometimes seems extreme but it sure helps in the long run.

That nasty picture above was just one plant. The rest are yellow and orange, but some in the middle of the plant not bottom. I wonder if it makes sense to toss out the 2 worst out of 12 plants?

Yes it seems extreme with plants with not many healthy leaves. But I guess the risk of spreading is worse...

Do the spores stay in the soil after the plants’ roots are removed?

I sprayed Serenade bc that’s what I have and pulled 2 weak plants

Thanks Bill

One more question. It may be coincidence, but right before the fungal outbreak I had diatomaceous earth on the mid to lower leaves, that sat on the plant for 2-4 days until it rained. This was to target flea beetles that were chomping holes through my plants leaves.

Could diatomaceous earth cause some of these problems by smothering the leaves?
