I made the mistake of reading online advice. I sprayed my very healthy plants (Squash, Eggplant, Grapes, etc...) with nearly pure peppermint oil to protect them from aphids, etc. Six hours later I looked and noticed greater than 60% of all of the leaves looked wilted and burned.

Is there anything I can do to nurse the plants back to health? The stems look ok, just the flowers and leaves look damaged.

Some commercial sprays have peppermint oil, but only like 6 to 8 percent. I read a homemade spray, that i belive was like, 1Tbl oil and dawn dishsoap to a gallon of water and keep agitated.
Plants will recover if its not to hot.
Pictures, where you live, temps. and your zone would help.
In mean time wash your plants off, if you haven't allready.
Anything i say, could be misrepresented, or wrong.

Oil based products in the hot sun can do some damage to leaves.
