The U.S. Environmental Protection Agency and the New Zealand Environmental Risk Administration have decided to eliminate the use of cotton phosphorus | Cotton phosphorus (azinphos-methyl) is a neurotoxin with good insecticidal effect. It is used for pest control of crops such as strawberries, summer fruits and potatoes. It is a broad-spectrum organophosphorus insecticide. But the U.S. Environmental Protection Agency believes that it carries an unacceptable risk to farm workers and also kills fish when it spreads into the water. The U.S. Environmental Protection Agency decided that no one should use cotton-retaining phosphorus after the summer of 2012. Cherry growers were one of the last farmers to use cotton phosphorus. For 50 years, growers have been relying on cotton phosphorus to protect fruits from worms and deworming. Cotton-protecting phosphorus comes from the nerve gas of World War I. When they spray cotton phosphorus, every little worm in the orchard will surely die. A small number of growers have been trying to find alternatives to cotton phosphorus. The New Zealand Environmental Risk Authority (ERMA) has been evaluating the use of cotton-containing phosphorus as part of a broader review of compounds and has decided to phase it out of the market within five years. The agency will also strengthen controls during this period to reduce threats to people and the environment. These include a ban on domestic use or aerial spraying and a limit on the number of uses in a year. ERMA stated that the elimination period was set at 5 years because this is the time required to develop alternative products. |
