For the next six weeks, the Environmental Protection Agency may promulgate the most sweeping anti-insecticide regulations in U.S. industry. If it does, billions of dollars worth of crops may be lost annually, children may die from cockroach related asthma and Lyme disease carrying ticks may profilerate. At issue is a class of insecticides known as organophosphates. They kill bugs by interfering with their central nervous systems. For some crops there are absolutely no approved alternatives: for others the alternatives are either less effective or more expensive.
