Aphids on Lily leaves

I asked the people at Water Garden Gems in San Antonio about a means for
controlling Aphids on Lily leaves. Here is their response:

Good afternoon,
Aphid's can be controlled by using Safer Soap and spraying the pads. Be
careful not to do it in the middle of the day, try to do it in the evenings
so that the sun does not shine on the pads. Safer Soap is a safe product to
use in and around the pond and can be purchased in most nurseries or Wal
Mart in the gardening section.
Thank You
Connie

I did find it at Wal-Mart. It is called "Safer 3-in-1" and comes in a 24 oz
spray bottle. The cost was $5.

Insecticidal soap such as Safer's works. So does a garden hose, just spray
them off, let the koi eat them.

is it safe for fish????? soap?????? I dont think so. Ingrid

That was my thought too. I'm not entirely sure what it is about soap that
harms the fish. It's less problematic with low-foaming soap, and this
probably is low-suds, but I don't think any soap is _safe_.

I think it removes the slime coat on the gills... which are essential for oxygen
uptake. Ingrid

Sorry Ingrid, but that response is fear mongering, with out any apparent
basis in fact.

The active ingredient in Safer Brand Insecticidal soap is 49% Potassium
salts of fatty acids.
Which has an LC50 of 18-30ppm on fish.

In a 1300 gal pond, 18ppm is about 0.234 gal or 0.88 liter. Since the soap
is at 49% concentration it converts' to half gal or 1.8L of product.

A few spritzes of the stuff is about one ounce? Or about 0.6ppm. At that
concentration it's not even worth bothering about.

LC means lethal concentration. So harm without killing them will occur at lower
doses.
If you evenly spread that "spritz" out into the 1300 gallons the toxicity is low.
Dont know about your koi, but when they see me they come straight to where ever I am
and you start spritzing the leaves there is going to be a much higher concentration
locally where it is being spritzed and the fish will swim thru the area of higher
concentration.
this is also the problem with putting DRY potassium permanganate directly into the
pond. where you put it into the pond is going to have a very high concentration
especially because it sinks and doesnt dissolve instantly. the fish swims thru the
areas of high concentration and fries their gills. even using a stock solution is
tricky requiring mixing into the water with one hand while pouring with the other ...
the flapping hand hopefully chases the fish away.

nope, not for my fish. Ingrid

And the often-discussed problem with using LC & LD levels in approving any
kind of chemical is that it assumes the only issue we're concerned with is
fatalities. There is likely no data available at all on long-term effects
of sub-lethal concentrations of the soap (though there are probably figures
for LC25, etc - and it would be worth knowing whether the lethal effects
drop off quickly or slowly from the 18ppm value).

If your fish recover completely from any damage due to a low concentration
of the soap (if there's no sign of gasping, they probably will - but those
would be your koi you're experimenting on!), then only the LC values really
matter, but if there's permanent damage, every time you use the soap things
will get worse. I can't help thinking there's a good reason for saying, on
the label, not to use it around aquatic animals.

fwiw, "...highly toxic to aquatic invertebrates. The LC50 was determined to
be 0.57 ppm in a 48-hour acute toxicity study with Daphnia magna". A neat
coincidence that you picked that number (I wouldn't have thought "a few
spritzes" was really as much as an ounce)

_My_ fish have always got most of their food from browsing for aquatic
inverts.

*Note: There are TWO Koi-Lo's on this NG*

I would still remove the plant to another place to spray it. You never
know! I would not want any kind of insecticidal soaps in my ponds. Some
people recommend hosing the aphids into the water for the fish to eat. That
didn't work for me as not one koi, goldfish or rosy-red would eat them.
