The new Mother Earth News just arrived and one article had a recipe for
a safe insecticide. I gotta try this as soon as I can find the soap,
locally if possible. I found it at the manufacturer's site. Dial.
Recipe and instructions:
Shave one-quarter bar Fels-Naptha soap (about 1 inch) into 1 quart
heated water and stir until dissolved, This is your concentrate.
Put 1 teaspoon concentrate per quart into sprayer.
This insecticidal soap is a contact poison, spray directly on the
little bastids, in the home, garden, orchard, etc. For additional
killing power, add, 1/4 Cup rubbing alcohol per quart.
Naphtha is not naphthalene. You may be old enough to remember cigarette
lighter fluid... that's one of the naphthas (a name given to several
highly volatile and flammable hydrocarbon mixtures). Naphthalene is
mothballs, two fused benzene rings. Nasty stuff.
Anyhow, I chased it down in the Household Products Database...
it lists Stoddard Solvent, aka one of the naphthas
You might want to compare with something like plain soap like Ivory
and dilute alcohol sprays, as well as a few dish detergents. California
Extension Service (I believe) in the late 80's did a series of comparisons
of efficacy and leaf damage on hort crops using Safer soap, Hiway soap,
and several other things. Winner was Ivory dish detergent, diluted.
Don't remember the reference... do remember the winner. ;-)

If you have 93 cents, add it to 5 dollars and buy insecticidal soap!
It's designed for what your intentions are about. Just a thought. OR,
like I said before go to a healthfood store and buy Dr. Bonners
I think I will.
I opened the bar and have had it sitting by my desk since yesterday and
the odor is overpowering and not pleasant.
Smells like things I rail against.
John Bachman would likely approve of the Fel smell.

I use the Fels Naptha laundry soap recipe. It has a unique clean
odor, neither objectionable nor pleasant. But, it is a harsh soap for
use on the skin. Can't guess what plants might not tolerate it. I

Mostly in preparation for the attack... have not really had any major
problems yet, just a little gnawing going on that I am ignoring Maybe
the soil has improved and I won't have a problem??? I can hope.
Flea beetles, cabbage loopers, and Japanese beetles (or bean beetles or
whatever they are called, the little greenish stripey bastids that gnaw
hell out of the beans and cuke foliage), which always show up! The
cabbage worms I usually deal with by hand, but it is a never ending job
and those damn moths are flighty, often working at night.
THough, I am more than surprised, I have had no cabbage worms on the
brussels sprouts. They do attack them right? THey played hell with
the broccoli last year and we didn't plant any this year.
No cabbage either.
The flea beetles are bad on the eggplants only.
Crap, outta time. Must wake Sleeping Beauty.
Charlie, look what Ivory soap did for Marilyn Chambers. Think what it
could do for your 'maters. Sounds like a good investment to me . . .
Charlie, why are the ladies lookin' at me like that?
Going back to sleep now.
Coloribus gustibus non disputatum (mostly)
??????? I don't know! I just reread it and it is not clear.
The addition of alcohol is suggested at the end of the instructions, so
it sounds like you add it too the spray solution. Two ounces seems a
little ineffective if mixed in with the concentrate if you only use 1
tsp concentrate per quart. I'm guessing the alcohol would evaporate
out of the concentrate after too long.
I think I'll try the alcohol in the spray mix.
Good question, thanks!
