Really need to see a photo if possible. Descriptive terms like "curled" and "soft" mean very different things to different people. Plus it would help to know if this is in a container or the ground and what specific insecticide and fungicide you sprayed and why. Both pests and disease can cause curling and so can sprays so what symptoms did the plant have that made you feel the need to spray?

Lastly - your location please so we can get an idea of what "heat" means to you. Folks up north think 85 degrees is heat while we further south laugh at that temp. ;-)

Thank you for replying. It took me a little bit to get those pictures up. I’m right outside Kansas City, MO.

The tomato’s are planted in a raised bed. I sprayed Orthos Bug-b-gone for landscaping and gardens. For a fungicide I am using bionides copper spray. Both are diluted in water.

That is spray damage of some kind in the photo. If no herbicide drift - and you are absolutely sure of that - then most likely culprit is the Bifenthrin in the Bug-B-Gone. But keep in mind that herbicides can drift for almost a mile and that mulches from unknown sources can also contain herbicides.

If not herbicides then either it was mixed incorrectly and over-concentrated or perhaps over-applied in the direct sun and heat of the day? Or, depending on application timing of the different sprays, if the ingredients in the two interacted you can get that same result.

That is one of the primary reasons why using chemical pesticide sprays prophylactically or mixing 2 different chemicals is often so strongly discouraged.

About all you can do is rinse the plants off well with fresh water, monitor the new growth, and hope the plants can recover from the damage. They usually will.

It could also be from mulch, if you are using hay or straw that has been treated with a herbicide.

Ya know, I did spray just before the sun was the strongest. Also, I’ll space out spraying chemicals instead of doing them on the same day I’ll wait a few days in between.

Herbicide damage. Tomatoes are VERY sensitive.

What did you spray?

My neighbors and I haven’t sprayed herbicide for a long time. As I posted earlier, all that was sprayed just prior was a fungicide and an insecticide.

As stated, herbicide can drift from places beyond your immediate neighbors. And it can be in mulch and compost.

Dig dirt and Gorbelly....thank you for your input. My responses have given the impression that I didn’t put any importance on the herbicide. My apologies for that...I will pay more attention to that right now and in the future.

What do you all do to help your tomato’s stand up to that better?

You can't do anything but prevent exposure. Test all mulch and compost before applying to your plants. Plants can sometimes outgrow a very mild case of herbicide injury, but once a plant has been significantly affected, that plant is done, period. It won't produce anything worthwhile. That's why awareness of herbicide is an important thing to spread. My neighbors sprayed herbicide carelessly once and damaged ornamental and edible plants all over the neighborhood. They didn't know.

To test mulch and compost for herbicide, plant peas in it and compare to a control pot containing verified non-contaminated potting mix. Peas sprout quickly and are sensitive to this class of herbicides, and the foliage will grow out distorted if the mulch or compost is contaminated.
