Critics Wary Of Plant Poison In Border War

    U.S. struggles to keep Mexican drug cartel violence from spilling across border.

(AP)  The U.S. Border Patrol plans to poison plants along a 1.1-mile stretch of the Rio Grande riverbank to eliminate the dense foliage used by suspected illegal immigrants and criminals to hide.

The $2.1 million pilot project is due to begin this week. If successful, it could be expanded along up to 130 miles of river in the patrol's Laredo Sector, as well as other parts of the U.S.-Mexico border.

Critics say the action is similar to the Vietnam War-era Agent Orange chemical program and worry that it could be harmful over the long term. Opponents are also concerned that the spraying will occur near the cities of Laredo and Nuevo Laredo, Mexico.

"We don't believe that is even moral," said Jay Johnson-Castro Sr., executive director of the Rio Grande International Study Center, located at Laredo Community College, adjacent to the planned test area. "It is unprecedented that they'd do it in a populated area."

The Border Patrol and U.S. Environmental Protection Agency officials say the chemical is safe for animals. The program is designed to keep border patrol agents safe and help make their jobs easier.

"We are trying to improve our mobility and visibility up and down the river," said Border Patrol agent Roque Sarinana.

But the program still has many detractors.

Members of the Laredo City Council have raised concerns about the spraying program and called on Mexico President Felipe Calderon to intervene. And Mexican officials are worried that the herbicide - called Imazapyr - could threaten the Nuevo Laredo water supply.

Imazapyr was registered in the United States in 1984. The EPA concluded in tests that "there is a reasonable certainty that no harm will result to the general population, and to infants and children from aggregate exposure to imazapyr residues."

A U.S. government outline of the project indicates the Border Patrol is going to test three methods to rid the 1.1-mile bank of river of carrizo cane, which has thick stalks that form tight, isolated trails that can be dark and all but invisible from higher up on the bank.

One method calls for the cane to be cut by hand and the stumps painted with the herbicide. Another involves using mechanical equipment to dig the cane out by the roots, possibly without the need for the herbicide.

The third and most controversial removal method calls for helicopters to spray Imazapyr directly on the cane, until all plant life in the area is poisoned.

The Border Patrol said that after using the herbicide, it plans to make the river's edges green again by planting native plants.

The cane is a non-native plant introduced by Spanish explorers centuries ago. Johnson-Castro said he has no issue with removing the cane, just the method of getting it done.

Laredo Mayor Raul Salinas said he believes federal officials when they say testing shows the chemical is not dangerous. But he also realizes opponents have concerns to evaluate.

"It is a complicated situation because we have to think about protecting our border," said Salinas, a retired FBI agent. "But let's do it in a sensible, reasonable way to make sure humans won't be harmed, nor the vegetation, nor the animals, nor the environment."

    2 words: quinolinic acid (photolytic breakdown product of imazapry)

    "Better yet, we should just feed the illegals caught rat poison. Then, they might stop coming?"

    I really hope you were just joking. That is just so wrong! We need reasonable methods to protect our borders, but these are mostly just decent, poor, downtrodden human beings who are desperate for a better life.

    Thereby, increasing the welfare and crime rate more than any single bill ever passed, (with the possible exception of drug and alcohol prohibition)

    This could be done without sprays.

    Not one mention of soil erosion. Not that we let much water down to the border anyway.
    Posted by nomealaska at 11:45 AM : Mar 24, 2009 Our government is going to poison the river to defend the failure war on drugs,,,,,,the people fighting on either side are corrupt. fighting something that they could never stop,,,,,something that should not be illegal in the first place,,,,wake up J. Edgar Hoover has been gone for a long time now,,,if his communist witch hunts did not expose him for what he was,,,his hatred for marijuana was the same type of witch hunt. Marijuana is in no way as evil as the man ran the FBI for decades. Simple decriminalization would solve the cartel problems that are faced,,,not poison and not enforcement...it is time to legalize and create jobs and revenues for the people of America.

    Hey I've got an idea! Let's hire one of those psuedo military contractors to do this.

    The (in keeping with the Bush model) folks from Lakennut will then take our inflated payments of US tax money and hire the illegals that are crossing to cut down the cane...for 2 dollars a day.

    Plus, thanks to Bush, in a few years we Americans can use the same crossing to sneak into Mexico - where the jobs are!

    Thanks for the mess GEORGE!!!

    I think our government has gone completely crazy now.America is turning into a police state.What is bad is the fact that they have to use chemicals to destroy natural vegetation next to a river.Some one needs to remind them that they must follow the same laws as the people do,,,,,in other words,,,the Texas chemical applicators handbook says you cannot spray ANY CONTROLLED PESTICIDES to any land that has runoff into a river or stream...IT IS AGAINST FEDERAL LAW.......It is making me sick watching the people in Washington do as they please after passing laws prohibiting the people from doing those actions.......If they keep robbing us and poisoning us they are going to find themselves in a revolution soon.

    I feel like throwing up. We're preparing to decimate a river just to keep Mexicans from coming here? How about we just accept the fact that people move from poor countries to rich ones, and work forward from there?

    We tried this non-sense before in Vietnam. We called it agent orange then and it back fired. Didn't help find any enemy and killed many of our own due to the toxic effects. I don't see that there is a place for this.

    It looks like the Office of Homeland Security was also looking into intorducing certain insects that lay their eggs in carrizo cane and kill the plant. However, introducing yet another non-native species to wipe out the first may come with its own problems. I found very little online info on the plant itself. I wonder if it might be edible to any animals. Goats and sheep have been used in the past to clear plant life from hillsides and difficult terrain. In this case...? I am afraid the EPA statement about "reasonable certainty" that the spraying won't cause harm to humans sounds less than persuasive.

    Can't they just hire Mexicans to remove the plants. I heard that they do pretty good yard work!

    So now Mexico is evidently one of our enemies. Haven't we done enough damage to our reputation in the world. Defoliate the banks of the Rio Grande? Are you kidding? Someone please stop us from militarizing the border with Mexico, it is just so wrong. Being from Texas I will not go near the border anymore, not because of the Mexicans but because of the all the checkpoints and police presence. It is really creepy.

    Why don't they just rent some weed whackers?

    This idiocy will not only poison plants but it will poison people, the water and any wildlife that drinks out of the river. Hello?! Morons?! Lets not let this be a kneejerk reaction. Think of the ramifications prior to killing.

    Sounds like spray the area, only poor people live there anyway. I'd be mad if I lived there, especially with all the deformities in Vietnam most likely caused by Agent Orange. My brother-in-law worked in the supply area over there. I wonder if that's what caused his son to have extremely high blood pressure, lose both his kidneys and die from his 3rd heart attack.
