Crop Observations from Southern Illinois

Be on the Lookout for Wheat Diseases

Posted by Robert Bellm -

Depending upon where you are located in the southern third of the state, wheat development ranges from Feekes Growth Stage 9 (flag leaf fully emerged), to approaching Feekes Growth Stage 10.5 (heading complete, but not flowering). This is a critical time period for wheat development, and fields should be carefully scouted to monitor for fungal leaf and head diseases. On May 3, Dr. Carl Bradley wrote and excellent Bulletin article on scouting and management of wheat foliar diseases.

Be careful not to confuse disease symptoms caused by viruses with disease symptoms caused by fungal pathogens. While there are numerous fungicides that that help effectively manage fungal diseases, these fungicides provide absolutely no control of virus diseases.
