Source: Sunday Times (UK) Contact: Sun, 28 Jun 1998 FUNGUS NIPS DRUG IN BUD The fungus that could be used against the opium growers looks a little like the mould found on old bread. It develops on the poppies as a greenish and black fuzzy powder. Once introduced to a crop, the fungus can spread through the aerial transmission of its own spores, of which millions can be produced by one plant. But the rate of contamination can be increased by spraying from the air. Once a plant is infected, it begins to show symptoms within three days; by 10 days there are visible lesions on the stem and leaves. Within weeks it may die. The bud of the opium poppy contains the sap that is the raw material for heroin. The seed-pod is slit open while on the plant, allowing the sap to ooze out. Usually it is left to dry in the sun and the brown, latex-textured residue is removed later with a scraper. Morphine is isolated from the opium by a series of boilings and filterings, using commonly available chemicals, leaving a product that resembles brown sugar. It is then compacted into blocks and transported to more sophisticated laboratories to produce heroin. It takes 12-14 hours to produce heroin from morphine, and 5kg-10kg of heroin crystals require 50kg-100kg of opium. If the poppy-killer fungus is used, it would not be the first time that a natural agent was deployed as a biological weapon. American scientists have developed a type of algae to kill mosquitoes by shutting off their digestive systems; in Britain, a bacteria derived from soya is used as a pesticide by organic farmers; and in Colombia, farmers are experimenting with a fungus that kills off the borer beetles that threaten their coffee crop. - --- Checked-by: Mike Gogulski
