The officials, led by Environment Minister Eduardo Verano, said in interviews Wednesday that the Colombian government has made no such decision regarding tests of the chemical herbicide tebuthiuron, sold commercially in the United States under the brand name Spike. The New York Times reported in a front-page story Saturday that the government, bowing to U.S. pressure, had agreed to test tebuthiuron to kill coca crops. The article contained no quotes, citations or other data to support the assertion that testing had been approved. The story was reprinted last weekend in several American newspapers, including The Dallas Morning News, the Chicago Tribune and the international edition of The Miami Herald. Andrew Rosenthal, foreign editor of The New York Times, declined to comment on the story or the government's response. Mr. Verano said that the government still was reviewing preliminary studies of the herbicide and that research teams were "deeply divided" over whether to allow its application on Colombian soil, even under test conditions. He added that no tests on coca crops have been approved and that the government still must review and accept a testing design before such steps are taken. Mr. Verano added that, as the chief government representative on the matter, he holds the final say on whether to conduct tests with tebuthiuron. The National Police chief, Gen. Rosso Jose Serrano, and the director of anti-narcotics enforcement, Col. Leonardo Gallego, have spoken in favor of testing tebuthiuron, arguing that it can be applied to crops more effectively and with less danger to crop-dusting pilots than the chemical herbicide currently being used. U.S. and Colombian scientists currently are trying to find ways that tebuthiuron can be tested, and ultimately put into full-time use, while allaying fears of international environmental groups that it could denude large patches of tropical land where it would be applied. "They are proceeding with the design of the experimental stage, and that is where we are now," Mr. Verano said. "Tebuthiuron will not touch Colombian soil, it will not be used on any Colombian land, until a design protocol is submitted and approved. This has not happened." He noted that tebuthiuron's manufacturer, U.S.-based Dow AgroSciences, had issued a statement in April warning, "Tebuthiuron is not labeled for use on any crops in Colombia, and it is our desire that the product not be used for coca eradication as well." Mr. Verano said: "This chemical could be very dangerous to the environment. We will not agree to test it until we are absolutely certain that the tests can be conducted safely. That is why we have not yet approved even the design for a test." A multidisciplinary national anti-narcotics council also has received design plans for such a test and has agreed to the concept of testing tebuthiuron, but the panel has not moved beyond the review stage, said Bernardo Reina, adviser to the council's director. "We have approved the concept of a test only. The design still must be approved," he said. "There has been no government approval for testing to begin." Copyright 1998 The Dallas Morning News - ---
