Agent Green is a genetically engineered fungus used to sabotage the growth of illegal drug crops. US State Department officials have revived a controversial scheme to use biological weapons to forcibly eradicate coca and opium poppy crops in Colombia. The eradication technique calls for testing types of the fungus Fusarium oxysporum (dubbed "Agent Green" by the Sunshine Project) and using airplanes to blanket coca and poppy-growing areas of the country with the biological agents. A previous attempt to use Agent Green was shelved amidst protests in 2000-01 and following a determination by then-President Bill Clinton that it could run afoul of the Biological Weapons Convention. If the renewed US pressure continues, it is very likely to generate protest by civil society organizations, indigenous peoples, and Colombia's neighbors, all of whom oppose the fungus.
