In 2015, after nearly 20 years of study, U.S. Environmental Protection Agency scientists recommended chlorpyrifos be banned for all uses due to its confirmed links of prenatal exposures with impaired cognition, autism, ADHD, developmental delays, memory deficits and other serious neurodevelopmental issues. However, one of the EPA’s first decisions under the Trump administration was to reverse this recommendation.
Golf course and agriculture representatives say they want to keep chlorpyrifos as an option “in their toolbox.” But entomologists say plenty of far safer pesticide alternatives exist, and even golf course and agriculture literature recommend alternatives.
Any notion that we need this nerve agent pesticide to fight invasive species and bluegrass weevils is a ruse at best and a frightening idea at worst. Do we really want to look for new ways to use this pesticide? Former American Academy of Pediatrics President Dr. Fernando Stein said that chlorpyrifos is “unambiguously dangerous and should be banned from use.”
There’s a reason why DDT, PCBs, lead in paint and other harmful chemicals have been banned in our country – and as history has shown, actions taken to protect public health often come too late. There is simply no justification for this dangerous pesticide to be used in Maryland or elsewhere.
