How strong of a solution did you use? The standard recipe of 1 T of soap to one gallon of water has never burned anything I have used it on. However it also comes with the warnings to never spray in the heat of the day or full sun and to "lightly mist the bugs, never drench the leaves".

Other than rinsing them well with fresh water I don't know that there is anything you can do but wait and see if they send out new growth.

I did something similar to mine and 2 days later one very nice looking yellow squash plant died of bacteria wilt, completely on the ground as if I hadn't watered it in a week, but still a green color.

The leaves are slowly deteriorating ,but new ones are popping up everywhere. Maybe yours will pop back in shape.

It was said "I did something similar to mine and 2 days later one very nice looking yellow squash plant died of bacteria wilt,..."

Coincidence, not cause & effect.

No, but the leaves were tinged and there is new growth, didn't mean to scare anyone with bacteria wilt. Maybe it wouldn't have happened to a healthier plant, after the soap attack I must have weakened the plant.

Was not the cause of it for sure!

If it was bacterial wilt then new leaves would not be growing. If infected with BW the plant will not survive. Why do you think it was BW and not the application of soap? Cucurbits are very susceptible to soaps and insecticides.

The others survived, but one died outright with no warning. The others had some damage along the edges of leaves, but grew new ones, the one that died of bacteria wilt, died. The plant was on the ground, wilted, flat on the ground in every leaf, and nothing was sprouting, it died.

The rest just have tinged leaves.
