Glum Blotch Symptoms on Wheat

Glum Blotch (fungus - Septoria nordorum): Glume blotch occurs on the nodes, spikes, and glumes causing blackened areas. Stems are weakened and may bend or break just above the nodes. Seed may be shriveled, reducing yields and quality of grain. Seed treatment, rotation, deep burial of crop residue, foliar fungicides, and resistant varieties will reduce disease losses.
