I have used a home remedy bug spray that had dish soap,ammonia,and tobacco juice in it with no ill effects,but I would test it on a leaf first to be sure. I would think it depends on the concentration.Maybe someone else will chime in here.

Someone sent this to me a few years ago, I think it's time
for another round. Kay

A sluggish elegy for you

Oh, curse you wicked gastropod
in silent stealth do you maraud
And search for something to devour
A tender leaf, perhaps a flower

In sly,, nocturnal diabolique
Your herbal carnage, havoc wreaked
Upon the innocents so floral
Just what are you, mollusk immoral?

Methodical, your telltale plunder
Another victim ripped asunder
Vile messengers of this perdition
And all of this with no dentition

Your legions spawned from moist recess
in numbers I can only guess
You multiply in dark design
Emerging now and then to dine

In dank, subterranean grexes
Invertibrates with double sexes
Do procreate, oh my, egad!
Can you be both mom and dad?

Your viscous trails are mere derision
I'm coming soon to some decision
I don't think we can coexist
Unless you promise to desist

If you don't curb your rising tide
I just might use methaldehyde
So if you're wise, you'll play your cards
And migrate to my neighbor's yards!

Ammonia is used in fertilizers so it should not hurt the plant so long as you don't over do it.

It can burn the plant if too strong, usually browns the leaf tips....ever put fresh from the farm animal manure that was not composted enough on your garden?- same thing. Its the ammonia in the manure that burns the plants. That's why you dilute it water.

Oh yeah, never thought of that. Yes i do put fresh cow manure on them, yes i dilute it. I make a soup out of it. Thanks a bunch Berry.
Thanks for the poem, loved it.
