On Tuesday night, the state will spray an aerial pesticide over tens of thousands of acres of southeastern Massachusetts, as officials try to kill mosquitoes carrying eastern equine encephalitis.
The virus killed two people in 2005 and has been detected earlier than usual this year, prompting the aerial spraying for the first time since 1990.
Since that time, there's been a rise in organic farming in Massachusetts, leading to new concerns about potential environmental consequences.
