Kansas State University plant pathologists and entomologists reported the first known case of corn stunt disease in Kansas, following similar cases in Oklahoma and Missouri. As of August 29, the disease has been confirmed in multiple Kansas counties, including Sedgwick, Pratt, Stafford, Edwards, and Riley.

Although the overall incidence is low, the disease is concerning due to its impact on corn plants, leading to stunted growth, multiple small ears with loose or missing kernels, and possibly red or purple discoloration of leaves. Corn stunt is spread by the corn leafhopper, which has also been recently identified in Kansas.

Kansas State University Row crop plant pathologist Rodrigo Onofre emphasized the importance of laboratory testing to diagnose the disease accurately. Producers are encouraged to submit suspected samples to the K-State Plant Disease Diagnostic Lab and contact local extension agents for assistance. A video on identifying and collecting corn leafhopper samples is available online.
