Default Fungal? Orange Yellow leaves

I gave a foliar feeding of Kellogg Fish/kelp concentrate Monday or Tuesday and thought I was getting a slight burn even though I did it at night. out of 15-18 plants 12 have healthy thick stems and the others have either thin stems or thin foliage. A friend told me this is fungal. I have Serenade and just sprayed with copper.

I'm scared bc todays rain into night seems to be spreading something to some of the healthy plants.

Please help.

These pictures are from today. The last one is just to show a healthier plant with just a few yellow leaves, and an overall view of the garden.

Thanks in Advance
-Charlie

That black branch is suspicious of something like late blight, cut it off and keep an eye on it.
The yellowing is hard to say, it looks like the leaf first died than it was attacked by a fungus (classic problem), but I'm not sure why.

Yellow lower leaves are not unusual, remove them and consider using baking soda or bleach spray.

That is probably just some gray mold. Either spray with a copper spray or the bleach spray and it shouldn't be a problem if it is just starting. Is that a black tomato variety?
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.

I have that on a lot of plants and usually do every year - it is just a lot worse this year and hope it gets better!! I pick the leaves off, use bleach, baking soda, and fungicide but am worried and hope it stops!! I have picked off roughly 3 bushels of leaves from 100 plants. I always thought it was early blight

Thanks. I will post better pictures soon. Right now I have a wasp swarm trying to nest outside my door a few feet from garden.

I’m finding it hard to take proper photos that depict 3 dimension and the full story. I was vigilant with fungicides - Copper then serenade in May-June rains. But I shifted to pests with thuricide and spinosad. Then after a Foliar Feeding I started to see more funny leaf issues. Even last nights storms made things worse I think.

Yup, mine are still turning yellow on some plants. Don't know if a wet spring, old wood mulch, or what that makes it worse this year. I think the wasps lay their eggs on the tomato worms and kills them? But a nest near the house gotta deal with that I guess.
Attached are photo's from all sides of house and the different plant sizes that have been affected by whatever.
Remember I just picked dead stuff off so what you see is what I missed You have to look close on the Micro Dwarf and the Olive Hill .....

Sorry about the sideways - can't figure how to correct it.

Here are more, I wonder if the Cucumber has the same thing?

I think I’m gonna hit them with aspirin water tonight

This place rocks! Thanks for sharing your photos. I use a Mac app to make them smaller and automatically flips them.

http://www.plantea.com/plant-aspirin.htm

This one says 325mg per gallon

http://www.tomatoville.com/showthread.php?p=445101

https://www.pennlive.com/gardening/2...nt_diseas.html

My research shows 200-500 mg per gallon and any more than 2x 325mg is dangerous. And make sure it’s uncoated.


Why don’t you remove those lower yellow leaves on the cucumber? Seems like a lot of foliage already

Ami has a rant here about disease prevention. I think daconil.

Picture #4 is the soil/mix is too wet. That does narrow the problems down some. What exactly it is - I don't know, but it needs a lot less water. My opinion, don't water it until it needs it. Get rid of the leaves that look bad. The bleach spray wouldn't hurt.
