For those who dont know the facts:
One of the world’s newest and safest pesticides,
spinosad, was fermented in a laboratory—from a rare soil bacterium discovered by a vacationing scientist in the soil of an abandoned Caribbean rum distillery in 1988. This combination of the natural and the high-tech won the Environmental Protection Agency’s Green Chemistry Award in 1999.
Spinosad is so safe for humans that “protective clothing” for applicators means long-sleeved shirts, pants, and shoes with socks.
Now, additional testing has found
spinosad not only protects hundreds of field crops, but can also tackle such huge world insect problems as 1) protecting millions of tons of stored grain from voracious borers, moths and beetles; 2) stopping huge clouds of grasshoppers and locusts from creating Third World famines; 3) helping corn growers stop rootworms on millions of acres.
Organic farmers reject most of modern science, including biotechnology and fertilizer made with natural nitrogen taken from the air. However, organic farmers agree with high-tech farmers and the EPA on the benefits of
spinosad.
Key
spinosad formulations have already been organically certified, and the product was used to save California’s big organic farming industry from an invasion of Mexican fruit flies with a region-wide spray program in 2003. Without
spinosad, California would have had to fight off the fruit flies with a synthetic pesticide, and many of the state’s growers would have lost their organic designations.
Spinosad is already registered for 250 crop uses in more than 70 countries. California is using
spinosad on nearly a million acres of crops per year, mostly on lettuce, oranges, celery, broccoli, and spinach—at fractions of an ounce per acre.
Spinosad has a unique mode of action: overexciting the nervous systems of insects that ingest them. It doesn’t kill spiders, ladybugs, insect-predatory mites or other beneficial insects—except honeybees. It’s safe for fish and marine species. It doesn’t produce any cross-resistance with any other chemical class. It’s fully compatible with integrated pest management.
Much of the world’s massive grain stocks have been protected until now with organo-phosphate pesticides, which are not nearly as safe for grain inspectors and handlers.
Grasshoppers and locusts are among the Third World’s most severe crop risks. Populations of the insects periodically explode into massive local invasions, leaving famine in their wake.
Spinosad has proven virtually as deadly to grasshoppers as malathion, though it takes a week instead of a day to kill them.
Spinosad could be the preferred control on rangeland, and also help prevent the swarming insects from developing resistance to malathion.
More than a million Africans, mostly children and pregnant women, die of mosquito-borne malaria each year. Humanity had not found a new weapon against mosquito larvae in 30 years—until
spinosad was tested. It works as wells as the best current pesticides, is environmentally safe, and its novel mode of action means it can be rotated with current mosquito larvacides to prevent resistance.
Spinosad may also prove to be a potent weapon for farmers on millions of acres infested with rootworms, particularly because of its favorable environmental profile. Pesticide-wary Europe is trying for accelerated
spinosad corn approval, to save millions of acres of cornfields from a spreading rootworm invasion.
Organic farmers are thrilled to have a more effective pesticide than sulfur, copper sulfate, and natural Bt sprays that quickly wear off.
Dow-Agrosciences, which developed
spinosad, says it has been constantly surprised at the breadth and effectiveness of the compound. It plans to test even more
spinosad uses—especially where it can be used as a bait, to make use of its exceptional performance when bugs swallow it. Dow-Agrosciences and other crop protection companies are also looking actively for more
spinosad-type bacteria.
For the sake of the humans fed by high-tech farming—and the wildlife protected by its high yields—let’s hope they are successful.
