A farmer speaks
out
The move toward natural farming is motivated by one very powerful fact:
it works and pesticides don't.
by Paul Buxman, reprinted from Farmer to Farmer, with permission
raditionally, when we have had an outbreak of pests,
we thought the most simple solution was to kill them. But this has not really
worked. If it did, we would not be out there year after year killing them
again and again. With pest control, we have often dealt with the obvious
problem - the bug itself - without looking for the more obscure cause: a
farming system out of balance. This is only natural.
If a fire breaks out in a hay barn, you are not going
to sit there asking yourself, "I wonder why that fire broke out?"
You are going to extinguish the flames before they spread. There will be
time to think of causes later. With the flames out, the immediacy of the
problem subsides and we are drawn to other concerns, satisfied that things
are safe once again. You would think, however, that after the thirtieth
or fortieth time a fire breaks out in the same barn we would decide something
must be wrong somewhere and try to discover the cause. Farmers are at that
point now. We are tired of putting out the "pest fires" in our
fields at great expense. We want to get at the cause of these outbreaks
and see if we can't end this continuous fighting of pests.
Pest enhancement
Modern pest control measures do not control pests at
all. In fact, they actually help to bring about conditions which favor pest
infestation. They might better be described as "Pest Augmentation"
or "Pest Evolution Enhancement." Killing pests with poison is
a poor way to achieve control. It is only a way to postpone dealing with
the actual cause for the infestation. For more than 40 years experience
has proven that it does not work. The more a farmer sprays poison, the more
he will have to spray. Farms with a disrupted ecology become addicted to
pesticides because all natural forms of pest control have been lost.
Why have farmers continued this costly practice of trying
to achieve pest control by spraying pesticides, even when information about
biological control has been around for years? The reasons are actually quite
simple.
Some forty years ago, farmers decided that an eight
percent crop loss due to pest damage was too much. They reached for the
newly-invented bug killers. One application killed the pests but threw their
farm ecologies out of whack. They were forced to reach for other poisons
to kill bugs which had been controlled biologically just a few years earlier.
One spray led to another. Spray rates, timing, and special mixes became
more and more critical. One missed spray or misapplication could spell disaster.
With so much at stake, the farmer no longer felt knowledgable enough to
make pest control decisions. Enter the pest control advisor, provided "free"
by the pesticide supplier. Integrated Pest Management, IPM, which had essentially
been occurring naturally on our farms, gave way to a new and very different
IPM: Integrated Pesticide Management.
A complete generation has now grown up with the notion
that the farmer's essential tasks are spraying, disking and irrigating.
To suddenly alter or eliminate any of these tasks can literally create an
identity crisis for the farmer.
An act of faith
Part of the problem of converting to natural farming
methods is the seeming requirement of "faith" on the part of the
farmer. Trusting in something we can't see may be fine for church, but will
it work in our field? A 500-gallon spray rig full of poison appears to be
the superior weapon against pests when compared to hard-to-see predators
that may or may not be out there. Even if they are there, how many pests
will they kill? Maybe they won't kill enough to do any good. And if the
only way to establish predators is to stop using poison, and it takes a
year or so to get them established, what happens to the crops in the mean
time? Besides, the poisons have basically been doing their job... haven't
they?
Actually, pesticides haven't been doing all that well.
With all the different pesticides created since 1940, you would think that
the percentage of pest damaged fruit would have been reduced over the years.
But instead, the USDA estimates that American farmers are now losing approximately
twelve to fifteen percent of their crops to pests each year. That is almost
double what we were experiencing before we had all these chemicals. We seem
to be going backwards.
New materials, old methods
The transition period which people worry about is also
not nearly as dangerous as people may think. Many "gentler and kinder"
materials are becoming available today. Soaps, pheromones, certain botanicals,
and even some of the old "standby" pesticides, when used at reduced
rates, can provide crop protection with a minimum of predator disruption.
What happens when you switch to less disruptive materials? You will find
that you need less and less pesticide to achieve control. The less you spray,
the less you need to spray.
Monitoring pest and predator counts will be necessary
through the transition period. A farmer may want to enlist the help of an
IPM specialist, such as a member of the Association of Applied Insect Ecologists
(AAIE) or other qualified personnel. It will be their main function to help
you establish balanced ecological systems which run themselves, requiring
as little chemical input as possible. This doesn't exactly mean, however,
that you can totally relax. Farmers should observe their fields daily. The
farmer's observations plus the weekly visits by the IPM advisor will yield
the most informed decision making.
When our farms become more natural, many good things
begin to happen. We save money, protect air and water quality, revitalize
our soils and improve fruit quality. It's not so hard. Spray as little as
possible, encourage habitat for beneficial insects, raise cover crops, and
spread manure, compost or other organic wastes once in a while. While it
may not always be easy, it may be simpler than you think.

farmers with "how to" information, relevant research, reports
on important issues, and by creating a forum for farmers to ask questions,
get answers, and report on their own problems and results. Published 6 times/year,
