Bliss / San Francisco Chronicle / August 14, 2002
The
boysenberry harvest on my small organic farm in Sonoma County
just ended, and the blackberry harvest will begin soon. So I
relax
for a moment and look out over the peaceful plant kingdom here
in the
Redwood Empire.
Yet,
the possibility of the government authorizing the forced
spraying of pesticides on my private property without my permission
disturbs me. The powerful wine industry, which so dreads the
glassy-winged sharpshooter, has persuaded state and federal
authorities to provide millions of tax dollars to spray urban
and
rural areas where the tiny harmless-to-people insect might arrive.
Such chemical spraying on my land would break my heart and destroy
my
organic food farming.
I've
spent more than a decade (other organic farmers have spent
longer) carefully nurturing my soil to grow healthy, chemical-free
food. Now, the California Department of Food and Agriculture
threatens to destroy all those years of work within minutes,
sacrificing my farm to the wine industry.
I
use farming practices such as diversified crops, including cover
crops, and plants that attract beneficial insects, which protect
my
crops from pests. I spread compost and mulch and release chickens
into my field to scratch and cultivate, eat bugs and leave behind
their manure as fertilizer. I observe nature carefully and farm
with
its design in mind.
So
the thought of returning home someday to find that pesticide
sprayers have trespassed on my land and sprayed without my permission
frightens me. My neighbors include children, elders and people
with
compromised immune systems and chemical sensitivities, such
as
asthma. We would be hurt by such deadly chemicals that have
been
proven to damage not only insects but also people.
The
chemical solution is how agribusiness and the California
Department of Food and Agriculture think. A monocrop such as
wine
grapes invites insects to a banquet. The CDFA thinks that they
can
solve the problem that agribusiness created by a extensive spraying
campaign, which eventually benefits the chemical companies.
The bugs
adapt and resist.
The
sharpshooter is not the basic problem. It is merely the symptom
of a deeper problem. Natural predators that have historically
eaten
such pests have either had their habitats destroyed or been
killed by
pesticides. The sharpshooter will not be the last new pest to
migrate
our way as the climate changes and Earth heats up.
The
short-term gain of eliminating some of today's pests by chemicals
causes a long-term loss by further disrupting nature's balance
--
polluting the soil, air and water and killing many beneficial
insects, such as pollinating bees, ladybugs, spiders and dragonflies.
The birds and rodents that prey on insects and the fungal diseases
that keep pest numbers down are also vulnerable to pesticides.
The
costs of spraying pesticides are much more than the aerial
sprayer and the chemicals. Most of the costs are hidden and
include
the worsened health of animals, plants and humans. A few thousand
dollars of pesticides can produce many thousands of dollars
of
medical care, as well as considerable suffering and loss of
work. If
agribusiness continues with its chemical addiction, pest problems
are
likely to worsen.
I
have another idea -- a quarantine. Let's defend our region's
plants
and people by heading the sharpshooter off at the pass. Quarantines
have successfully kept other pests out. The powerful nursery
industry
does not favor such a solution, but it would be effective and
without
cost to human health.
Let's
kick the chemical addiction now, before it worsens. Instead
of
arming ourselves with chemicals, Sonoma County organic farmers
and
gardeners, environmentalists, health advocates, parents and
others
have organized the No Spray Action Network. Last year, it worked
closely with the local agriculture commissioner and grape-growers
to
come up with alternatives to forced pesticide spraying. Organic
options, such as kaolin clay, are now being used by some
grape-growers. Picking the bugs off the plants and vacuuming
them
away can also be effective, as well as less expensive. Similar
efforts to NSAN's by citizen groups have cropped up in Napa,
Santa
Cruz and Mendocino counties.
Perhaps
these insects are a wake-up call to examine how synthetic
chemicals unbalance nature. We should apply a medical motto
to
farming and demand that farmers and the CDFA "Farm Without
Harm."

Pest control
How
the state of California deals with glassy-winged sharpshooters:
--
-- 'Infestation' defined: The detection of five or more adult
sharpshooters within any five-day period and within a 300-yard
radius, or if a viable egg mass or nymph is found other than
in
association with a shipment of plant material to a commercial
nursery. An "infested area" is within one mile of
an infestation,
unless a greater geographic area is determined appropriate.
--
Treatment in a rural area: If an infestation is detected in
any
agricultural setting within the County, including but not limited
to
vineyards, orchards, or production or retail nurseries, the
pest
shall be treated at the cost of the property owner or leaseholder,
in
a manner approved by and under the supervision of the county
agricultural commissioner.
--
Treatment in an urban area: If an infestation is detected in
urban
or residential areas of the County, the infestation will be
delimited
and eradicated where feasible. If eradication is not feasible,
the
perimeter of the infestation will be monitored and the infestation
will be contained within the smallest possible area, as determined
necessary by the County Agricultural Commissioner.
--
Extermination methods: In general, according to the Sonoma County
agricultural commissioner's office, the eradication of the
sharpshooters involves establishing an extermination protocol
with
property owners. Although chemical pesticides are always an
option,
other methods include removal of host plants and vacuuming up
egg
masses, nymphs and adults.
But
if the treatment is not conducted to the satisfaction the county
agricultural Commissioner, extermination can be undertaken as
provided in the Food and Agricultural Code of California.
