Field identification of corn gray spot disease

Gray spot disease occurs mainly in the leaves, leaf sheaths, and temporal lobes of mature corn. The pathogenic bacteria first infect the lower part and cause disease. When the climate conditions are appropriate, it can be extended to the entire leaf and cause the leaves to die. In the early stage of the disease, the water-stained haze gradually expands to a light brown stripe or an irregular gray-to-brown stripe. It extends parallel to the veins and forms a long rectangle, which is more obvious in the light; the lesion is gray in the middle and has brown edges. Line, a white or gray mold layer is produced on the back of the leaf blade at the later stage of the lesion.
