Disease Information

Symptoms of Fusarium head blight in wheat

Fusarium head blight is caused by the fungus Fusarium graminearum. The fungus attacks the grain directly and can result in serious yield losses. Losses may also be compounded by mycotoxins that are produced by the fungus in diseased grain. Symptoms of disease include tan or brown colored lesions that may include single spikelets or large sections of the wheat head. No single disease management option can completely eliminate the risk Fusarium head blight; therefore, the disease is best managed with an integrated approach. This integrated approach begins with selecting the best available genetic resistance but may also require the timely application of a fungicide to suppress the disease when weather favors disease development. Contact your local extension office for more information about management options in your area.
