Lisa is right to bring to our attention the toxicity of
agricultural chemicals and pointing out that naturally occurring “organic”
substances can be toxic. These substances are not used because they are
safe to living creatures – quite the contrary. Of course, given the choice
between effective alternatives, we should choose the one that is safer.
There are people in the world that garden because their lives
depend on it. There are those that garden because their livelihoods depend on
it. Gardeners must evaluate risks of crop damage and loss along with other
factors in determining production techniques.
In an attempt to increase water retention, improve soil
fertility, and control weeds I have utilized wood chip mulches. By doing so, the
risk of plant loss from slugs has increased. So far, I have been successful in
repelling slugs in my garden.
I no longer use pyrethrum/rotenone for an aphid spray because
it was not especially effective. For me, it did not prove to have that “rapid
knock down” characteristic. I no longer use it as a slug repellent. Soap is
effective and I found far greater success using it for aphids.
My neighbor's livelihood is dependent on 15 acres of
strawberries that he must protect from damage and loss. He uses, among
other synthetic pesticides,
metaldehyde/carbaryl snail baits known to be lethal when ingested by mollusks,
wildlife, livestock, pets, and humans. Far more so than I do, my neighbor, and
conventional farmers like him, contribute enormously to the American
"foodstream." And, everyone lives downstream from someone else. As
neighbors, consumers, and gardeners, we must continue the search for safer
alternative agricultural methods and welcome dialog with those using
conventional agricultural practices.
Lisa is right to point out the dangers of pyrethrum/rotenone
and I should have directed your attention to what is likely to be a safer
alternative – soap. I just hope that it still proves effective
and that others continue to search for alternative slug control.
This year, I have frequently noted 2 pair of Canadian geese
in the alfalfa field across the fence. I believe they are part of the family of
14 geese that lived across the river from the garden last year and seem to
be quite "tame." If they venture into the strawberries after the snail
bait has been applied, they may well be killed. They might eat my slugs but I
believe that I must find some way to keep them out of the peas and most
everything else. Please be patient with my search for solutions. I'm trying
a scarecrow. Any suggestions?
