1. You said, "it is an insoluble acid" when you should have said "it is poorly soluble." That is why I said "No."
2. The only rubbing alcohol that I have seen is 70% ethanol but 91% isopropanol is commonly sold at drug stores and you can buy 95% ethanol at liquor stores.
3. It is an empirical fact that many plants can be sprayed with up to 50% methanol in water without damage. Methanol sprays have been reported to be beneficial to C3 plants. Bananas are C3.

That is why I prefer to use methanol as a solvent for plant sprays.

If by "steam" you meant "stem," then, no, because the stem of even tall bananas are as short as possible with no spaces between petiole nodes. Besides, I would have to dissect the banana plant to examine its stem. The object was to lengthen petioles or what others call "pseudostem."
