Corn rootworm hatch is predicted to either commence or continue in fields from near the Illinois River mainly south of Havana, Illinois to west of Jacksonville, Illinois and east into east central and east southeast Illinois as well as west central and central Indiana. Additional corn rootworm hatches are predicted to commence this week in portions of southwest and south central Kansas with the risk spreading northeast into portions of central and northeast Kansas by the end of the week and into next weekend. Growers in these areas are urged to monitor their fields for signs of larvae and take appropriate action if it is needed.
