1) I have heard of phytotoxicity to ethanol, but have also heard recommendations to use it with
fertilizers...

2) Methanol is a known absorption accelerator, a la Jerry's Grow.

3) While I have desiccated buds by spraying way too much, I have never killed a plant with
isopropanol.

Why not ethyl alcohol? Laquer thinner seemed to do the job, too.


I managed to kill a very large specimen of Paphiopedilum fowlei by
spraying it with ethyl alcohol. When I asked why on the old Orchid
List Digest, I was told that ethyl and methyl alcohol will penetrate
plant tissue more easily than isopropyl alcohol. Perhaps the effect
depends on the orchid leaves (soft paphs versus hard and leathery
cattleyas), but I've never had any trouble with isopropanol, so why
risk it?

As always, test a single leaf before spraying the entire plant
