Fusarium Head Blight or “Scab”
Fusarium Head Blight Identification and Management
Symptoms of Fusarium head blight include tan or light brown lesions encompassing one or more spikelets. Some diseased spikelets may have a dark brown discoloration at the base and an orange fungal mass along the lower portion of the glume. Grain from plants infected by Fusarium head blight is often shriveled and has a white chalky appearance. Some kernels may have a pink discoloration.
Management:
Avoid the most susceptible varieties (2014 results, 2015 results) and planting into corn residue, use ScabSmart Risk Map Tool to time Foliar Fungicides. Optimize your ground or aerial application equipment.
