DRUG CONTROL OR BIOWARFARE?

The US is strong-arming Colombia into unleashing the latest weapon in the
war on drugs: a powerful new herbicide. But along with killing coca plants,
the toxic fungus may pose serious dangers to the environment and human
health -- threats so compelling that Florida has suspended plans to test
the fungus for its own anti-drug efforts.

The big American suddenly stood up, leaned over the table and said to the
Colombian in a low voice, "You'd better be careful not to talk to the press!"

Dr. David C. Sands, scientist and entrepreneur, was meeting with advisors
to the Colombian Ministry of the Environment last March to push a new
drug-war weapon marketed by his company: a special toxic fungus which would
kill coca plants. The Colombian scientist who raised Sands' hackles had
pointed out that the fungus could also attack humans with weakened immune
systems -- a condition common among the often undernourished and generally
unhealthy poor coca farmers and workers in the tropical rain forests of
Colombia, where Sands wants to carry out a massive spraying program. "He
didn't care," said the Colombian, who asked not to be named.

Sands is not the only party pushing this new biological weapon. The US
Congress is demanding that Colombia apply the controversial fungus in order
to receive $1.6 billion in emergency bailout funds for Colombia's
antidrug/counterinsurgency strategy called Plan Colombia. Last March, Rep.
Benjamin Gilman, R-N.Y., tacked on an amendment to the pending aid bill
requiring President Clinton to certify that the Colombian government "has
agreed to and is implementing a strategy to eliminate Colombia's total coca
and opium poppy production" using, among other means "tested,
environmentally safe mycoherbicides." Myco fungus; herbicide plant killer.

Steve Peterson, an official with the State Department's International
Narcotics and Law Enforcement division, says they want to see
mycoherbicides used because they would be "more cost effective and more
environmentally friendly" than chemical herbicides.

The trouble is that abundant evidence indicates that the only mycoherbicide
being considered for this purpose, Fusarium oxysporum, may in fact, in
massive application, pose serious dangers to the environment and human
health. Florida has put an indefinite hold on its plans to test the fungus
for its own antidrug efforts after environmentalists and a state official
warned that it could mutate, spread rapidly, and kill off other plants
including food crops. And for over a decade, coca growers in Peru have
accused the US of secretly applying the fungus there to attack coca plants
- -- in the process also harming food crops and farm animals. Moreover, the
fungus can, under certain circumstances, cause lethal infections in humans
with weakened immune systems. None of this, however, has dimmed US
government enthusiasm for the project -- nor that of Sands' corporation,
which stands to profit if the fungus is adopted for widespread use.

Years of US-funded aerial spraying have so far failed to even slow
Colombia's thriving industries of coca plants, which produce the raw
material for cocaine, and opium poppies, which are used to make heroin. The
country's cocaine and heroin production has more than doubled since 1995.

The New York Times reported in early May that US-funded spraying of the
herbicide glyphosate (marketed as Roundup by Monsanto Company) may have
exposed scores of Colombian villagers to harmful toxins and damaged nondrug
crops. But the proposed Fusarium program, experts say, could unleash far
worse consequences.

The UN Cover

The Congressional hardball mandating fungus use follows a less coercive
approach to push Colombia into playing guinea pig for the first real
on-the-ground testing of the toxic Fusarium oxysporum strain called EN-4.
The first approach was through a United Nations Drug Control
Program-proposed project to establish a research station to conduct field
trials for eventual large-scale application of the fungus. Although the UN
representative in Colombia, Klaus Nyholm, said the draft agreement is "not
what the Colombians want," it certainly reflects what the US State
Department wants and has sold to Congress. The proposed agreement turns
over results of at least 12 years of research by the US Department of
Agriculture's Agricultural Research Service (ARS) to refine the use of
fungi against narcotic "weeds." The agreement openly takes political cover
under the UN umbrella. A May 1999 Action Request by Secretary of State
Madeleine Albright pushes the UNDCP to get other countries to ante up "in
order to avoid a perception that this is solely a (US government) initiative."

Which, of course, it is. "It was an American interest," said Nyholm. "It
wasn't my idea.

While the concept of using herbicides against weeds and camouflaging
foliage (such as Agent Orange in Vietnam) is not novel, using them against
crops is. Ironically, the great majority of research on Fusarium focuses on
combating it as a major food-crop killer. The soil-borne mold infects crops
by secreting toxins into their roots, which then putrefy and dissolve the
plant's cells, often eventually killing them, or worse, poisoning humans or
animals who feed on contaminated plants or plant products. The fungus can
survive in soil for years.

The idea of using a fungal herbicide to kill drug plants began in the 1970s
after a fungus, later identified as EN-4, began to kill off the coca at a
soft drink research plantation in Kauai, Hawaii. In 1986, the ARS began a
full-blown research project, classified for a time, to find a biological
agent to kill coca. By 1991, the government had invested at least $14
million in it. Congress has now given the State Department $23 million
originally slated for mycoherbicide development in the US, which State
plans to pass on to the UN.

By getting the UN to take on the fungus project, the US not only gets
political cover, but makes it harder to get information about the program.
Unlike the US government, the UN has no Freedom of Information Act
guaranteeing outsiders access to official documents.

The US Congress' arm-twisting to make Colombia use the fungus even before
it has been tested for environmental and human safety raises the
fundamental issue of informed consent by the Colombian people. The program
could easily be construed as having a nonpeaceful purpose, thus
contravening the international Biological Weapons Convention and morphing
it from "biocontrol" into "biowarfare." While both the US and UN stridently
object to the latter term, the secrecy surrounding the project -- the lack
of independent monitoring of the US fungus development, the lack of media
exposure to the project, and the classified nature of the development
program in its early years -- leave serious questions unanswered.

Colombia Targeted

When we visited Colombia in late March to research this article, the UN
proposal had already landed in the Ministry of Environment, which must
approve its use. At a meeting with ranking officials, however, it became
clear that the Ministry had precious little to go on in making their
decision. The vice minister of the environment and her aides gathered
around the conference table were asking us, the journalists, to supply them
with information. Neither the US government nor the UN agency pushing the
plan had given the Ministry the detailed available documentation on the
genesis and development of Fusarium oxysporum that they would need to help
decide if it was safe to apply. Ministry staffers were reduced to trying to
cull information from the Internet. What they had found there was evidence
that Fusarium oxysporum could mutate to gobble other plants and could be
dangerous to animal and human health.

Ministry advisers also told us that Peruvian organizations had not
responded to queries on the fungus epidemic that had affected coca fields
there. Since 1991, Peruvian coca growers have charged that they have seen
helicopters fly over their coca fields emitting a brown or white cloud
which caused their coca and food crops to die and sickened their farm
animals. Many of the farmers believe these helicopters are part of an
American antidrug campaign, a charge the US denies. Research in 1993 by a
US-funded Peruvian scientist showed that many of the food crops were
infected by the same fungus species that had killed the coca.

There are many troubling aspects to the UN proposal. It maintains that EN-4
already exists in Colombia, which is convenient since introducing a foreign
pathogen to the country would present a problem under international law; UN
representative Nyholm, however, says there is no EN-4 in Colombia. The
proposal admits that fungus development, large-scale production, storage,
and application techniques for Fusarium already exist; now, it says, all
that's needed are "large-scale" field trials to compare different
formulations and application rates, and assess the environmental impact.
Yet it doesn't specify how they would measure the safety of these trials.
Nowhere in the draft is any noninvolved stakeholder monitor established to
oversee research and development in Colombia. And while the vice minister
says they have yet to approve the fungus, the draft proposal and State
Department "Action Request" both make clear that someone in the Colombian
government has already demonstrated a willingness to forge ahead, with or
without the Environment Ministry's approval.

This is no small matter in Colombia, home to the world's second most
diverse biosystem -- one that is uniquely vulnerable to the potential
threat posed by the massive spraying of a toxic, mutative fungus in vast
swaths of jungle.

Will It Really Attack Only Coca?

Department of Agriculture research documents on the fungus explicitly avow
that it is environmentally safe and would attack only coca. But Colombian
researchers and scientists are far from convinced -- especially given
Fusarium's notorious tendency to mutate.

Colombia is no stranger to Fusarium, a genus that includes several strains
besides EN-4. "There's a group of scientists who've been working [to
combat] Fusarium here for a long time," said Vice Minister Martinez. In
fact a major epidemic of one Fusarium strain hit the flower growers in the
plains of Bogotá a few years ago, and as a result, growers could no longer
plant in the contaminated earth -- they were forced to switch to soilless
hydroponics systems.

US scientists also maintain that the EN-4 strain will only attack plants
within the genus Erythroxylum, of which coca is one. But there are over 200
other plant species within that genus, many of which are found in Colombia,
which EN-4 could then kill besides its intended target. Plants of the
Erythroxylum genus are also used by indigenous populations for medicinal
and religious-cultural practices would also be at risk.

Moreover, a 1995 International Institute of Biological Control report on
the ARS fungus program admitted that non-Erythroxylum North American plants
under stress could be infected by EN-4. Surprisingly, this seems to be the
only research testing EN-4's ability to attack other plants. Luis Parra, an
herbicide expert recommended to us by the American Embassy who oversees the
glyphosate spraying of coca and opium in Colombia, says he has "a lot of
doubts" about Fusarium. "I don't believe in the specificity of these
organisms," he said. "It is very different to apply an herbicide (such as
glyphosate) that has a known and predictable and undeniable risk, than to
apply a microbe (such as a mycoherbicide) where the risks are still unknown."

Risks Extend To Human Health

While the US continues to murmur its "environmentally safe" mantra, Eduardo
Posada, head of the Colombian Center for International Physics, believes
that Fusarium can be devastating to people with lowered resistance due to
immunological diseases or malnutrition -- common conditions among the
farmers who often live near the coca fields that would be sprayed with the
fungus.

"The mortality rate for people infected by Fusarium is 76 percent," wrote
Posada in a letter to the minister of environment. He lists the scientific
literature indicating that Fusarium toxins are "highly toxic" to animals
and humans, and that the use of ants to spread the fungus (research
actually done by ARS scientists), could cause the ecosystem to be affected
much faster than imagined.

None of that, however, appears to trouble David Sands.

Pecuniary Interests? Presenting Dr. Sands

Vice Minister Claudia Martinez was ordered by the Colombian ambassador in
Washington to receive Dr. David C. Sands, a professor at Montana State
University in Bozeman and the vice president of Ag/Bio Con (agricultural
biological control), a company that markets the fungus. He is listed as a
major researcher of the fungus in the UN proposal, and it was he who first
isolated EN-4 for ARS in Hawaii. Yet now he seems to be more appropriately
classified as a free-lance businessman, hawking his company's version of a
fully developed fungus field-ready for "precision delivery from high
altitude" application by large C-130 cargo planes -- as a picture in his
literature shows.

Sands has no shortage of influential contacts. Ag/Bio Con has retained a
prominent DC consulting firm to lobby on bills related to mycoherbicide
development. The company's officials include a retired Air Force General
with a background in research; Sands has received a Navy research award and
has traveled with ranking US government personnel to a similar fungus
project in Kazakhstan and Russia. Through his Congressional connections, he
arranged a face-to-face meeting with President Andrés Pastrana in
Washington last January.

Sands did not return repeated phone calls for comment on this article.

Sands received nationwide attention for Ag/Bio Con in spring and summer of
last year, when he -- along with Colonel Jim McDonough, a former top aide
to US drug czar General McCaffrey who had taken a new job as Florida's top
drug official -- tried a similar sales job to use another strain of
Fusarium to control Florida's burgeoning marijuana industry. David Struhs,
the head of Florida's Department of Environmental Protection, reacted with
a strongly cautionary letter saying: "Fusarium species are capable of
evolving rapidly ... Mutagenicity is by far the most disturbing factor in
attempting to use a Fusarium species as a bioherbicide. It is difficult, if
not impossible, to control the spread of Fusarium species. The mutated
fungi can cause disease in a large number of crops, including tomatoes,
peppers, flowers, corn and vines, and are normally considered a threat to
farmers as a pest, rather than as a pesticide. Fusarium species are more
active in warm soils and can stay resident in the soil for years. Their
longevity and enhanced activity under Florida conditions are of concern, as
this could lead to an increased risk of mutagenicity."

Having been rebuffed by the state of Florida -- failing even to convince
the state authorities to initiate a simple experiment in a quarantined test
site -- Sands apparently set his sights on Colombia.

Two scientists who attended Sands' Colombia presentation said he first
presented himself only as a scientist, not mentioning Ag/Bio Con. When
asked about aerial application, they said he got flustered seeing they
already had his sales literature. His goal seemed to be to find four
hectares anywhere to use for a field trial.

The US Full-Court Press

That goal may be within reach. With the State Department pushing the UN and
the US Congress threatening fund cutoffs, the pressure is on and the stakes
high.

Two biologists who made a case on Colombian TV against the UN proposal say
colleagues have told them to cool the rhetoric. One, who asked that his
name not be used, says he received telephone threats after his statements
and is now watching his mouth. "Various times I've answered the phone and
they've said ... they know where they can find me, where I teach, at what
times I go out and I think that the country has enough heroes," he told us.

In response to the pressures, the Ministry of Environment has come up with
a preliminary counterproposal, calling for back-to-basic research on
"native micro-organisms with biocontrol potential" in the coca zones. The
proposal does not rule out the unpredictable and dangerous Fusarium, as
some scientists have demanded. But it does call for a long, meticulous
study emphasizing safety over the expediency urged by the State Department
and members of Congress.

After all, why should the people of Colombia expose themselves to a risk
the people of Florida refused to run? "If we're going to ask, for example,
the Colombians to do something," said Andy Bernard, spokesman for the
Florida Office of Drug Control, "we ought to have the guts to do it here as
well."
