 Some growers say they're delaying planting to avoid the heat, but still expect poor harvest for this growing season. This is RFD Illinois. With the RFD Ag Market summary for this Wednesday morning, I'm Jim Taylor. Corn, beans, and Chicago wheat all finishing Tuesday lower. July corn closing at $4.25 and a half, down $8. September corn down $7.75, $4.31 and $3.25. New crop December $4.43, down $8.75.
