SOUTHERN CORN LEAF BLIGHT

Description: Lesions of southern corn leaf blight are small (1/4?1" long x 1/4" wide) and tan in color. Lesions may be oval or have parallel sides. On some hybrids the lesions may be surrounded by yellow halos, but other hybrids may have reddish?brown borders.

Location: SCLB can be found throughout Ohio, but is more prevalent in the southern half of the state.

Time of attack: Wet humid weather favors SCLB, especially during periods of heavy dew and fog. Symptoms may occur as early as silking, but are more prevalent during later stages of development.

Management:
· Resistant hybrids
· Crop rotation
· Till residues
