Diplodia stalk and ear rots are caused by the fungus Stenocarpella maydis and commonly occur around mid to late ear fill. Stalk and ear rots can reduce the quality of the grain and compromise stalk integrity, leading to lodging, premature plant death, and potential yield losses. In-season management options are limited but proactive management strategies, such as product selection, reducing inoculum in the field for the following crop, and minimizing stress, can reduce the disease incidence next season.
