Many vegetables, fruits and nuts are not sprayed with pesticides so it doesn’t pay to buy organic for those items.
Conventionally grown vegetables with the lowest residual pesticide load are:
Cantaloupe (grown in America)
Grapes (grown in America)
Garlic (grown in America)
Papayas (non-GMO. Most Hawaiian papaya is GMO)
